Northern Ireland (often popularly referred to simply as Ulster) is located on the island of Ireland and is one of the four constituent nations of the United Kingdom. Despite its former reputation as being violent and dangerous the political situation has stabilized quite a bit. Although a few extremist paramilitary organizations are still active, the province is much safer to visit than formerly. Northern Ireland has a vast array of attractions which are of interest to tourists, from stunning landscapes and scenery to vibrant cities and interesting remnants of the country's past.
Northern Ireland was created in 1922 when its parliament opted out of the newly-created Irish Free State. It comprises six of the nine counties of Ulster (one of the four ancient Irish provinces), with the remaining three (Monaghan, Cavan and Donegal) staying in what is now the modern day Republic of Ireland. For this reason Ulster is a popular colloquial alternative name for Northern Ireland, even if it is not in the strictest sense geographically accurate.
Northern Ireland is home to numerous cities and towns. Below is a list of nine of the most notable. Other urban areas are listed on their specific county article.
The weather in Northern Ireland is notoriously unpredictable, and it is not uncommon to experience a full range of meteorological conditions in a single hour. As with the rest of the island of Ireland and Great Britain, the province is particularly susceptible to rain. Similarly to England, the weather is a common topic of conversation.
The population of Northern Ireland is largely made up of two groups. Although there had always been population movements between the west of Scotland and the north-east of Ireland, during the 16th and 17th centuries there was an organised settlement of people from Scotland known as the Ulster Plantation. Most came to work on new plantations which had been established in the area. The indigenous Irish population was predominantly Roman Catholic (at a time when this was the only Western Christian religion), whilst Scottish settlers after the Reformation were predominantly Protestant.
The religious difference turned into a political split: most Protestants are Unionists or (more extreme) Loyalists, supporting continued union with Great Britain, while most Catholics are Nationalists or (more extreme) Republicans. Nationalists and Republicans both want a united Ireland, but Nationalists (politically affiliated with SDLP political party) use peaceful political means; whereas the Republican movement (politically affiliated with Sinn Fein political party) sought violence as a means to a united Ireland up until 2004. Although segregation always existed, the situation reached boiling point in 1969 when the campaign for Civil Rights turned violent when protesters were attacked by Loyalist supporters. That was the start of the period known euphamistically as "The Troubles." In 1972, British Forces fired live rounds rather than plastic bullets at unarmed peaceful civilian protesters. 14 were laid to rest, on a day that has become known worldwide as "Bloody Sunday". The British Government gave reparations to the families of the victims. This was a major turning point in the support for the Republican movement as the civilian population felt they had nowhere left to turn. This also effectively re-polarised segregation along religious lines. Previously inactive paramilitary groups became re-established in the province, which sat precariously on the brink of civil war for many years.
In 1998, after years of sporadic negotiations between the United Kingdom, the Republic of Ireland and the paramilitary groups and local political parties, The Agreement was signed, signalling the end of violence in the province. This is often referred to as the Belfast Agreement or the Good Friday Agreement after the place or day on which it was signed. Although there was an almost immediate drop in the level of terrorist acts and rioting, it took several years for stability to settle on the region and for agreement to be reached concerning the devolved government.
Most people visiting have heard of the varying allegiances of Northern Ireland's people. However, to a traveller the people of Northern Ireland are friendly and warm towards visitors. You get the feeling that the people know the allegiances of each other, but to a traveller it can be hard to ascertain (at least until after the second pint of Guinness).
Citizens can self-identify as Irish or British solely or Northern Irish. Similar divides exist in referring to places, for example, to Nationalists, Londonderry is Derry, while to Unionists it is Londonderry.
The official languages for Northern Ireland are English, Irish and Ulster Scots. While used in various government and public organisations, Irish and Ulster Scots are rarely seen written and even less spoken. Nearly all education in the country is in English; therefore, there is no need to learn Irish, partly due to the fact that most non-Catholic schools do not teach it. Many Northern Irish people have little knowledge of Irish or Ulster Scots.
Although Northern Ireland is a small country, accents and dialects differ considerably throughout the country and even foreigners fluent in English may find it hard to understand people with certain accents. However most Northern Irish people will slow down and speak more clearly if they think you are having a hard time understanding them.
In schools English is taught as both a literature subject and a language subject. In most Catholic schools and some grammar schools it is normal for students to be taught Irish (although not widely used) and therefore certain schools have bilingual signs etc. French, Spanish and German (sometimes Latin) are taught in most schools or at least a few of these languages will be taught mainly at secondary school level. Unfortunately for native English speakers there is often no desire for them to learn other languages therefore a lot of Northern Irish people won't be able to speak to you in your native language but will try and make their English more understandable for a foreigner.
Immigration and visa requirements
Northern Ireland is a constituent part of the United Kingdom, meaning it has exactly the same entry requirements as England, Scotland and Wales. Citizens of the UK and Crown Dependencies can travel to Northern Ireland without a passport and have the automatic right to reside and work.
For more information of UK Immigration and visa requirements, see the UK's Home Office website .
Northern Ireland has three commercial airports, with the Belfast being the main gateway. A third airport in operates in Derry.
George Best Belfast City Airport  (airport code BHD): just 2 miles from Belfast city center, with magnificent views of the city of Belfast or Belfast Lough offered to passengers on approach and departure. The airport principally serves routes to domestic UK and Ireland, however bmi offers interline connections to its flights and those of the Star Alliance through Heathrow. These flights are code-shared with British Airways, therefore offering interline connections to its flights and those of the One World Alliance. Airlines using the airport include:
The terminal is served every twenty to thirty minutes from 06.00 - 22.00 by the 600 Airport bus  (£1.30 single, £2.20 return). Depending on traffic, the journey to Belfast's Laganside and Europa Buscentres should take no more than fifteen minutes. Ask at the airport information desk for a free shuttle ride to the near-by Sydenham railway station for trains towards Bangor, Belfast and Portadown. Considering the airport's proximity to the city, taxis cost less than £10 to most parts of the city and are an economical choice for small groups.
The Airporter is an hourly shuttle from Belfast's two airports to Londonderry/Derry. The journey to Belfast City Airport takes roughly a two hours.
Belfast International Airport  (airport code BFS) Locally known as Aldergrove (after the Royal Air Force base that has been there up until recently since before the commercial airport was constructed), the International Airport is further away from Belfast than the City Airport (but is close to the town of Antrim) and offers significantly more international destinations.
The terminal is served up to thirty minutes from 05.35 - 23.20 by the 300 Airport bus  (£6 single, £9 return) to Belfast Laganside and Europa Buscentres. Depending on traffic, the journey to Belfast's Laganside and Europa Buscentres takes about forty-five minutes. Taxis should cost no more than £25-£30 to Belfast City Centre.
You can also do it a much cheaper way By Taking the 109A (hourly service Monday to Saturday) ULSTERBUS service to Antrim from the stand outside airport ,(Bus/Train Station which costs £2.60 one wayby bus ) then once you get off the bus in Antrim Go up the steps into the ajoining Train station and buy a Ticket to Belfast Great Victoria street station the train stops in Mossley west /Belfast Central/ Botanic /City Hospital then Great Victoria street which is combined with europa Bus centre Great Victoria street is on the same name street in Belfast and is much more "Central" than Central station and is around the corner from city hall which is 10 mins away by foot. Check www.translink.co.uk for timetables for both Bus and rail Journeys by typing in 109A into search or click on Timetables for Ulsterbus and NI railways you will need the Londonderry-Coleraine -Ballymena-Antrim-Belfast Time table trains are usually every other Hour to Belfast so you might have to wait awhile at the station you can Also use the train station at Antrim to travel to Derry/Londonderry and Portrush as well as Ballymena /Cullybackey Coleraine and Castlerock /Bellarena if intending to Travel towards Derry?londonderry /Portrush be sure to board the Train travelling towards Derry /Londonderry this is always indicated on the Digital display on the front of the trains you will need the Belfast-Londonderry timetable for travelling to Derry/Londonderry.
The Airporter is an hourly shuttle from Belfast's two airports to Londonderry/Derry. The journey to Belfast International takes ninety minutes.
Ulsterbus operates various scheduled services to and from the airport to the main Foyle Street bus depot in the City. Services also operate to and from Limavady. For details of Ulsterbus bus services visit www.translink.co.uk. The typical fare to the city centre is £2.70 and the journey takes approximately 20-30 minutes.
Taxis are available from the airport, with the typical fares to the city centre around £12, with the journey taking roughly 15 minutes.
Despite decades of underinvestment and service cutbacks, Northern Ireland Railways  (a division of Translink, Northern Ireland's public transport operator) manages to maintain a small but increasingly reliable passenger rail network around the province, with four 'domestic' lines radiating out from Belfast.
Service is most frequent and reliable on the Portadown - Belfast - Bangor corridor, on which new trains offer frequent and fast suburban service. The line to Londonderry/Derry is exceptionally beautiful as it passes along the north coast after Coleraine, however travellers should note that the railway line is slower (two hours or more) than the equivalent Ulsterbus Goldline express coach (one hour and forty minutes). Contact NIR for information on tourist passes for exploring Northern Ireland by bus and train: with integrated bus and train stations in most major towns, the North is easily explored without a car.
The cross-border service to Dublin (with connections to other destinations in the Republic of Ireland) is offered by the Enterprise, a modern, comfortable and relatively fast train jointly operated by Northern Ireland Railways and Iarnród Éireann (who operate trains in the Republic of Ireland). The journey to Dublin takes around two hours, and there are eight trains a day, offering two classes of service.
Roads link Northern Ireland with the Republic of Ireland. However, pay particular attention to road signs when driving in border areas. In some places the border, being based on county boundaries, runs along the middle of the road while in others it's possible to cross into the South and then back into the North again within several hundred yards. Fortunately both jurisdictions drive on the left though road signs and speed limits in the Republic are now metric (kilometres) while road signs in the North are all imperial (miles).
There are currently no fixed border checks and there is complete freedom of movement between the North and Republic without a passport. Despite this however, non-UK, Irish or EU citizens must have a proper travel documents if they intend to continue further south of the border and vice versa.
Ferries cross the Irish Sea from Great Britain to Larne or Belfast in Northern Ireland. All the operators listed below offer special promotions throughout the year, and some also offer through ticketing with rail and bus services at each end.
Seat61.com offers informed and independent advice on how to book combined train and ferry tickets from any railway station in Great Britain to Northern Ireland.
It is also possible to get ferries to Dublin and drive to Northern Ireland.
If you are able to rent a car then driving around Northern Ireland is a very pleasant experience. Most drivers follow the rules of the road (except for speeding) and are quite polite towards other drivers. In some areas it is a pleasant gesture to wave at a passing car even if you do not know the person. Many of the roads on the North Coast are quite twisty but offer some beautiful scenery and there are many places to stop along the way and take in the natural beauty.
Northern Ireland's motorway system connects Belfast to Dungannon, Ballymena and Newtownabbey. All large towns and cities are well connected by road. The speed limits are:
Motorways and Dual Carriageways - 70 miles per hour (c. 112 km/h)
Other roads (outside urban areas) - 60 miles per hour (c. 96 km/h)
Urban areas (towns and cities) - 30 miles per hour (c. 48 km/h) and occasionally 40mph if signposted.
It is worth noting that many drivers constantly speed, usually 10 to 20 miles per hour above the speed limit. It is common for someone to be driving at 60 or 70 miles per hour and be overtaken by many other cars. It is no surprise then that speed traps and cameras are often quite sparse (except for in Belfast and near the border) and many drivers take this to their advantage. There have been many advertising campaigns over the years to combat the problem of speeding and drink driving ran by the Department of Environment which often include graphical adverts of the consequences of speeding and drink driving. A notorious accident blackspot in Northern Ireland is the circuit of main roads around Coleraine, Portstewart and Portrush which host the annual NorthWest 200 motorcycle road race - and as a result aggressive motorcycle riding is commonplace and the roads are heavily patrolled at most times of the year as a result.
Most main A roads are of a very good standard with many having overtaking lanes at certain points to allow you to pass slower traffic. B roads are often small country roads that are very narrow and have little (if any) road markings. Drivers must be careful on B roads when passing other traffic and may have to slow down and pull in when meeting larger traffic.
There is a comparatively high incidence of road accidents in Northern Ireland, and the province employs slightly different driving laws to the rest of the UK. One notable difference is that newly qualified drivers can be identified by 'R' plates which are displayed on the car for the first twelve months after their licence is issued. These plates are mandatory. Drivers displaying these plates are limited to 45 miles per hour (c. 72 kilometres per hour) on ALL roads, including dual carriageways and motorways. As with 'L' plates in the rest of the UK, drivers displaying 'R' plates are often the target of road rage and are not awarded a great deal of patience. Many Northern Irish people feel that R drivers are a hazard on the road when travelling at 45mph as it means other drivers are more likely to overtake in risky situations.
It is worth mentioning that Police security checkpoints are becoming very common once again. When approaching a checkpoint, dip your headlights and stop if indicated to do so. The police may want to check your licence and look in your boot (trunk). Don't worry, its all perfectly routine!
Northern Ireland is not as well served by car rental companies as is the Republic. Some Irish car rental companies offer a drop off option in Belfast while others have locations in Belfast City. Check with your car rental company if you are covered to go south of the border - it isn't always included automatically.

Translink operate the Northern Ireland public transport system.
English is spoken everywhere, although the distinctive Ulster accent can be more difficult to understand than other Irish dialects. Ulster Scots and Irish are used in some small communities. Do be aware though that the Northern Irish tend to speak quite rapidly compared to most English speakers, and have a huge arsenal of local words that are frequently dropped into conversation by speakers of all ages and groups. Expect to become acquainted with words such as 'aye' (yes), 'wee' (little), 'hallion' (person who behaves in a deliberately careless manner), 'we'un (literally 'wee one', meaning child), 'dander' (casual walk) and 'crack' (spelled in Irish Gaelic as "craic", meaning a good time/fun/a laugh, with no connotations of any controlled substances whatsoever).
Giant's Causeway- World Heritage Site and National Nature Reserve. The Giants Causeway is essentially an area of coastline and cliffs with very unusual and distinctive volcanic stone formations. The name comes from the local Legend of Fionn McCool, as it was said that the rocks were once part of a bridge (or causeway) which ended in similar rocks directly across the sea, in Scotland, but the connecting rocks were torn down by Benandonner when Fionn's wife tricked him into believing that Fionn was huge. It is an interesting site to see but come prepared for a long and intense walk. (Best to wear waterproof clothing and strong sneakers). Giant's Causeway is split up into six sections in walking order : 1. The Camel 2. The Granny 3. The Wishing Chair 4. The Chimney Tops 5. The Giant's Boot and 6. The Organ. All six parts of Giant's Causeway are different in shape and form and truly are a sight to be seen.Carrick-a-Rede Rope Bridge- The name literally means the rock in the road. Carrick-A-Rede
Ulster American Folk Park- Northern Ireland Visitor Attraction in County Tyrone open air museum explaining story of emigration from Ulster to North America in 18th and 19th centuries. There is an Old World and New World in site. Sites include the Weaver's Cottage, A Blacksmith's forge, Crop Fields, log cabins, smoke houses, and herb gardens. Museum restaurant available, open daily for snacks and full meals.
The official currency of Northern Ireland is the pound sterling. Bank of England notes are used but the four Northern Irish banks print their own versions, which tend to be used more often (Bank of Ireland, Northern Bank, Ulster Bank, and First Trust). Northern Irish notes are not valid in the rest of the UK (although many mainland shopkeepers usually accept them), but must be exchanged for Euro when departing to the Republic of Ireland.
Northern Ireland does a large amount of trade with the Republic of Ireland (where the Euro is used) and therefore many outlets in border areas and urban centres accept euro.
Virtually all shops and pubs in Derry and Newry will accept the Euro as payment. In addition, many major pubs and shopping outlets in Belfast city centre now accept euro. In particular, the pub company Botanic Inns Ltd and the shopping centre Castle Court can be cited as accepting payments for goods in euro. Many phone kiosks in Northern Ireland also accept euro, but by no means all outside Belfast itself.
A popular dish is the an assortment of fried food, called the "Ulster Fry". It consists of eggs, bacon, tomatoes, sausages, potato bread and soda bread. Some versions include mushrooms or baked beans. Fry's are generally prepared as the name suggests, everything is fried in a pan. Traditionally lard was used, but recently due to health concerns, it has been replaced with oils such as canola and olive. Historically, it was popular with the working class.
Some shops on the north coast close to Ballycastle, sell a local delicacy called dulse. This is a certain type of seaweed, usually collected, washed and Sun-dried from the middle of Summer through to the middle of Autumn. Additionally, in August, the lamas fair is held in Ballycastle, and a traditional sweet, called "yellow man" is sold in huge quantities. As you can tell from the name, it's yellow in colour, it's also very sweet, and can get quite sticky. If you can, try to sample some yellow man, just make sure you have use of a toothbrush shortly after eating it... it'll rot your teeth!
The cuisine in Northern Ireland is similar to that in the United Kingdom as a whole, with dishes such as Fish and Chips a popular fast food choice. Local dishes such as various types of stew and potato-based foods are also very popular.
It should be noted that, with the advent of the peace process and (until recently) the improvements in economic conditions for many people in Northern Ireland, there has been a great increase in the number of very good restaurants, especially in the larger towns such as Belfast and Lisburn. Indeed it would be difficult for a visitor to either of those cities not to find a fine-dining establishment to suit their tastes (and wallet).
Tesco NI hold a free event, 'Taste NI Food and Drink Festival', every year. The event celebrates the best of Northern Irish produce and invites the public to to take a culinary tour of the region, browsing food and drink stalls, meeting the people behind the local brands, sampling delicious produce and watching live cookery demonstrations from Northern Ireland’s top chefs.
This year's event is to be held in Belfast's Custom House Square on the 10th and 11th September, 2011.
The legal drinking age in Northern Ireland is 18. People at and above the age of 16 will be served beer and wine with meals as long as there is a consenting adult present. In general, restaurateurs are strict about this rule, while the operators of small local pubs and bars tend to be more relaxed. Depending on their license, most bars stop serving alcohol at either 11PM or 1AM. Some clubs serve until later, and some bars have (illegal, but widely overlooked) "lock-ins" where the doors are locked at closing time, but people can stay and drink for longer. This only takes place at the discretion of the bar owner, and such events operate on an invitation-only basis.
Northern Ireland has changed greatly in the years since the peace agreement was signed in 1998, though it's troubles have not entirely ceased. There remains a high incidence of terrorist incidents in Northern Ireland, with the UK Home Office defining the current threat level as 'severe' . Tourists, however, are not the target of such terrorist incidents and therefore are highly unlikely to be affected. Visitors should be aware that there is a significant risk of disruption caused by incidents of civil unrest during the contentious 'marching season' which takes place each year over the summer months. The US State Department advises visitors to Northern Ireland to remain 'alert' during their visit and to keep themselves abreast of political developments .
This being said, it should be remembered that most visits to Northern Ireland are trouble free and visitors are unlikely to frequent the areas that are usually affected by violence. Northern Ireland has a significantly lower crime rate than the rest of the United Kingdom, with tourists being less likely to encounter criminality in Belfast than any other UK capital.
In fact, Northern Ireland has one of the lowest crime rates among industrialized countries. According to statistics from the U.N. International Crime Victimization Survey (ICVS 2004), Northern Ireland has one of the lowest crime rates in Europe (lower than the United States and the rest of the United Kingdom), and even during the Troubles, the murder rate was still lower than in most large American cities (though this does not take into account the vastly lower population figures). In fact, the results of the latest ICVS show that Japan is the only industrialized place safer than Northern Ireland. Almost all visitors experience a trouble-free stay.
The Police Service of Northern Ireland  (formerly the Royal Ulster Constabulary or RUC) is the police force in Northern Ireland. Unlike the Garda Síochána in the Republic, the PSNI are routinely armed with handguns and/or long arms. The police still use heavily-armoured Land Rover vehicles; do not be concerned by this, as it doesn't mean that trouble is about to break out. There is a visible police presence in Belfast and Derry, and the police are approachable and helpful. Almost all police stations in Northern Ireland are reinforced with fencing or high, blast-proof walls. It is important to remember that there is still a necessity for this type of protection and that it is a visible reminder of the province's past.
As with most places, avoid being alone at night in urban areas. In addition, avoid wearing clothes that could identify you (correctly or not) as being from one community or the other (for example Celtic or Rangers football kits). Do not express a political viewpoint (pro-Nationalist or pro-Unionist) unless you are absolutely sure you are in company that will not become hostile towards you for doing so. Even then, you should be sure that you know what you're talking about. It would even be better if you acted that either you don't know about the conflict or don't care. Avoid political gatherings where possible. Many pubs have a largely cultural and political atmosphere (such as on the Falls Road, the mostly Nationalist main road in West Belfast, and the Newtownards Roads in predominantly Unionist East Belfast), but expressing an opinion among good company, especially if you share the same view, will usually not lead to any negative consequences. People are generally more leniant on tourists if they happen to say something controversial, and most will not expect you to know much about the situation.
Traffic through many towns and cities in Northern Ireland tends to become difficult at times for at least a few days surrounding the 12th July due to the Orange Parades and some shops may close for the day or for a few hours. The parades have been known to get a bit rowdy in certain areas but have vastly improved in recent years. Additionally, the last Saturday in August is known as "Black Saturday" which is the end of the marching season. Trouble can break out without warning, though locals or Police officers will be more than happy to advise visitors on where to avoid. The Twelfth Festival in Belfast is currently being re-branded as a tourist friendly family experience and efforts are being made to enforce no-alcohol rules aimed at reducing trouble.
Pickpockets and violent crime are rare so you can generally walk around the main streets of Belfast or any other city or town without fear during the day.
If you are dialling from one telephone in Northern Ireland to another, you do not need to add any area code. If dialling from the rest of the UK use the code (028). If dialling from elsewhere you can dial a Northern Ireland number by using the UK country code 44, followed by the Northern Ireland area code 28. If dialling from the Republic of Ireland, you can use the code (048), or you can dial internationally using the UK country code.
International phone cards are widely available in large towns and cities within Northern Ireland, and phone boxes accept payment in GBP£ and Euro. Buying a cheap pay as you go phone is also an option which can be purchased from any of the five main phone networks, O2-UK, Orange, Vodafone, T-Mobile and Three. O2 will have the best nationwide coverage and is the most popular network choice for many people. It's worth noting that any phone that is bought in Northern Ireland uses the United Kingdoms cell network and therefore when entering the Republic of Ireland you will be subjected to the usual EU roaming charges. It's quite common for phones in Northern Ireland to switch over to Irish networks when near border areas such as in the North West near Donegal etc. This is also true the other way around, as you can travel some distance into the Republic of Ireland while still maintaining a UK phone signal. The networks available in the Republic of Ireland are O2-IE, Meteor,Three and Vodafone IE so ensure not to get confused between the UK and Irish versions of O2,Three and Vodafone.
Free WiFi is available at various hotels and restaurants across the country. WiFi may also be available in various locations from unsecured networks from local businesses or pubs/clubs etc. Internet cafe's are less common in Northern Ireland but there are computers for use at the libraries which you may use after registering with the library service. Broadband speeds in Northern Ireland vary from fast to non existent. In towns and cities expect the Internet to be quite speedy but the further you get out from the towns the slower the Internet may become.
Northern Ireland is a strange place in that they'll often be nicer to tourists than their fellow citizens.
Generally speaking, people from NI are welcoming, friendly and well-humoured people, and they will often be curious to get to know you and ask you why you're visiting. However that does not mean that, on occasion, there are no taboos. It is sometimes apparent in some of the more geographically 'politicised' areas of Northern Ireland, that an insistence on a politicised conversation, especially concerning religious affiliation, may cause offence. Further on that issue, avoid bringing up issues like the IRA, UVF, UDA, INLA etc., or political parties, as it will fare similarly as the above taboo. Other than that, there are no real dangers to causing tension among the Northern Irish people. As with virtually all cultures, don't do anything you wouldn't do at home.
Also, Northern Irish people have a habit of gently refusing gifts or gestures you may offer them, do not be offended, because they really mean that they like the gesture, also you are expected to do the same, so as not to appear slightly greedy, it is a confusing system but is not likely to get you in trouble.
Tours of Belfast often include a visit to the Peace Lines, the steel barriers that separate housing estates along sectarian lines. These are particularly visible in West Belfast. It is common for private or taxi tours to stop here and some tourists take the opportunity to write messages on the wall. It is important to remember that there is a real reason why these barriers have not been removed, and that they provide security for those living on either side of them. Messages questioning the need for these security measures, or those encouraging the residents to 'embrace peace' etc, are not appreciated by members of the community who live with the barriers on a day-to-day basis and such behaviour is generally regarded as arrogant and patronising.
It is commonly perceived that visitors from outside the UK and Ireland have a limited knowledge of the political situation so do not make sweeping statements unless you know what you are talking about. This applies particularly to Americans (or others) who claim Irish ancestry and may therefore feel they have more of a right to comment on the situation. Do not give pro-Nationalist opinions in an area where it may not be welcome.
The terms which refer to the two communities in Northern Ireland have changed. During the Troubles, the terms 'Republican' and 'Loyalist' were commonplace. These are seen as slightly 'extreme', probably due to the fact that they were terms used by the paramilitaries. It is more common to use the terms 'Nationalist' and 'Unionist' today; these terms are more politically neutral. 'Loyalist' and 'Republican' still refer to particular political viewpoints.
A number of politically-charged names for Northern Ireland are used by some residents, the most contentious being "The Six Counties" (used by Nationalists) and "Ulster" (used by Unionists to refer only to NI). Visitors are not expected to know, or use, these or any other politically-sensitive terms, which will only be encountered if you choose to engage in political discussions.
Should it be necessary to refer to Northern Ireland as either a geographical or political entity, the term "Northern Ireland" (at least, when used by people from outside Ireland) is accepted by the vast majority of people.
If you need to refer to Ireland as a geographical whole, a reference to "the island of Ireland" has no political connotations, and will always be understood.
Visitors might be more aware of the fact that the second city of Northern Ireland has two English-language names, "Londonderry" (official) and "Derry" (unofficial but widely used). Nationalists, and everyone in the Republic, will invariably use the name "Derry", whereas Unionists strongly prefer "Londonderry". It is wise not to question anyone's use of either name over the other, and if you are asked "Did you mean Derry" or "Did you mean Londonderry?" you should politely say yes.
It may all seem confusing, but Northern Irish people won't expect you to know or care about every detail of the situation and, as mentioned above, will openly welcome you to their country. Young people tend to be more open-minded about it all and are not less politically motivated than their parents or grandparents.
The people in Northern Ireland are generally warm and open - always ready with good conversation. Of course, being such a small, isolated country with a troubled past has also led to a decidedly noticeable lack in social diversity.
It is worth noting that the majority of people you will encounter will be white. It isn't unusual to go a few days without encountering any multiculturalism, apart from other visitors or Chinese restaurants. This will make quite a change if you are from countries such as England or the US. Racism is not generally an issue, but in small towns and villages, don't be offended if you are stared at. People are simply not used to seeing non-white people and it is never hostile. However, due to the openness and rather frank humour in Northern Ireland, small, sarcastic comments may be made about the issue, in jest, if a local encounters someone outside of his or her own nationality. It is best not to react to this, as it is most likely just a joke, and should be treated as such. In fact, in Northern Ireland, a "mixed marriage" refers to a Catholic marrying a Protestant.
Gay and lesbian travellers should be aware that some citizens of Northern Ireland are not the most accepting when it comes to homosexuality. This is not necessarily due to the people being averse to it, but rather the fact that there are virtually no examples of any Gay and Lesbian communities outside Central Belfast. It should be noted, however, that parts of the capital (for example the University Quarter) are perfectly safe and accepting of Gay and Lesbian people, with both of Belfast's universities incorporating active LGBT societies.
However, there have been issues of more severe racism in parts of the province in recent years. Belfast is the most ethnically diverse area, but even so the city is over 97% white. Typically, incidents of racism have been confined to South Belfast, which has a higher mix of non-white ethnicities due to its location near Queen's University. After decades of little or no immigration, some people just find it hard to accept outsiders moving in, and racist attacks are usually to an immigrant's property, rather than the immigrants themselves.
