Transnistria (locally called by its Russian name: Pridnestrovie; and occasionally, in English: Trans-Dniester)  is a de facto state in Eastern Europe that has declared independence from Moldova, although it is only recognized by other breakaway states such as Abkhazia & South Ossetia. It roughly corresponds to the territory between the Dniester River and Ukraine.
Transnistria (official name Pridnestrovian Moldavian Republic; in Russian Pridnestrovskaia Moldavskaia Respublika, PMR) is a part of Moldova that declared its independence in 1990, entailing a civil war that lasted until 1992. Transnistria has not been recognised by any country but maintains its functional autonomy with military and other support from Russia.
Transnistria is divided into 5 administrative regions and two free cities.
Official languages in Transnistria are Russian, Moldovan (which is fundamentally identical to Romanian), and Ukrainian. Moldovan in Transnistria is spelled using the Cyrillic alphabet, although some people insist on spelling it with the Latin alphabet, which is a matter of dispute.The most common language used in shops, bars and taxis is Russian which practically everyone understands, Moldovan and Ukrainian are understood and spoken too but to a lesser extent.
Entering Transnistria is fairly straightforward by bus, train or car from both west (Moldova, usually Chişinău) and east (Ukraine, usually Odessa). Upon entering Transnistria, you will fill out a landing card. It is printed in Russian and English. Upon clearing immigration, this card, not your passport, is stamped - half stays at the crossing you entered; half stays with you until you leave Transnistria.
From the Bendery crossing to Chisinau, a taxi costs 100 to 150 Moldovan Lei. A marshrutka costs around 25 lei. Marshrutkas between Odessa and the Kuchurgan border (on the main road to Tiraspol) are fairly frequent and cheap.
When crossing the border between Moldova and Transnistria, you will be checked only by Transnistrian officials. There are also peacekeeping Russian and Ukrainian soldiers who may stop and search vehicles.
Entering Transnistria from Ukraine will not get you a Moldovan entry stamp. If you then leave Moldova through a crossing controlled by Moldovan authorities, you may have problems with the Moldovan immigration authorities, which may try to claim that you entered Moldova illegally. Exiting Moldova through Transnistria to Ukraine (whether having a Moldovan entry stamp or not) causes no problems - even a subsequent visit to Moldova through one of border crossings controlled by the Moldovan authorities doesn't raise problems with the border guards.
The Transnistrian officials may try to extort bribes from travellers at the borders, particularly on the main Odessa - Chişinău road. Be firm, unafraid and polite in insisting that you do not have to pay to enter or leave their country (unless driving your own vehicle, which incurs a $5 fee upon entry). This may be daunting - nowhere else can you be interrogated by the KGB wearing hammers and sickles - but bribes are not officially condoned and they will back down. Don't let the guards see your money, it will make them want some for themselves. If you feel beaten and feel that paying a bribe is the best way out, keep it low: $2 should be enough.
The best way to fight this corruption is to know about what's going to happen to you and be prepared for the games that the guards may play before travelling to Transnistria. Write a short paragraph stating that you know their tricks and how they work and that it's not necessary to have a Moldovan exit visa. Translate this into Russian while also providing a few of the complaint phone numbers listed below to show them you mean business. Also make sure to have a few copies of this document because they will most likely confiscate the first version you give them.
Complaints are possible , where you can go to the English version and click on hotline. You can also send a complaint to firstname.lastname@example.org (Transnistrian Customs). Future travellers will be grateful for your complaint! There is also a complaint hotline: +373 533 94578 or 92568. Try to memorize the number of the officer before he asks you for a bribe. Even the nicest officer can be corrupt! If you complain you should also state the time, the date and the name of the border crossing. You should also give your phone number. There is an English speaking officer responsible for complaints. You can reach him under +(373 778) 50986 or email@example.com.
It is no longer necessary to register with the police for stays under 24 hours: this is now done at the border. If you are staying longer, be sure the hotel or person you are staying with registers you or register yourself with the Ministry of Interior.
Entering Moldova through Transnistria from Ukraine
The official Moldovan stance on the missing entry stamp can vary.
Upon leaving Moldova, the immigration officials may insist that you should have registered with the Ministry of Information, Technologies and Communication (49 M Kogalniceanu str, Chişinău; now moved to 42 Pushkin str. office 116., Chişinău) within 3 days (72 hours) of arriving to get a Moldovan entry stamp. However, not all guards are aware that the Ministry of Information has stated that a Moldovan entry stamp is not needed and that your Ukrainian exit stamp is sufficient. It is worth your while being firm in pointing this out to them. Arguing this point with the officials can be daunting but they will back down after harassing you and making a few phone calls to verify the official stance.
Transnistria does not have its own international passenger airport (it has a military or freight airport), so the best way is to fly to Chisinau in Moldova and travel from there. It is also possible to access from Odessa in Ukraine via bus.
The only major railway stations are Tiraspol and Bendery. There are trains between Odessa, Transnistria and Chişinău as of July 2012. As of July 2012, there is train connection between Chişinău and Moscow, stopping at Tiraspol and Kiev (Leaves Chisinau 22:30, stop at Tiraspol around 01:30 and arrive in Kiev 12:30). Check Poezda CIS Railway Timetable for up-to-date, English language timetables.
Cars can enter but expect delays of up to an hour at border crossings in busy times. Note that foreign nationals driving their own vehicles are prime targets for border guards trying to extract bribes. According to the official hotline of Transnistrian customs there is an official road tax ($5). Ask for a receipt!
Note that not all border crossing points are allowed/able/willing to process foreign cars in customs. They may tell you to cross the border at a bigger crossing point.
There is a relatively frequent (about every 30 min, 07:00-18:00, less frequently as early as 05:00 and as late as 22:00) bus service connecting Chişinău and Tiraspol. Ask for return times when you arrive. Marshrutkas (minibuses) also run this route. Direct Odessa - Tiraspol buses are not so frequent. However, buses from Tiraspol to the border at Kuchurgan (Кучурган) and from Kuchurgan to Odessa are frequent.
Check AVPMR  for official timetables of local and international buses.
There are hardly any train connections within the country, so the bus -- if available -- will be your only choice. Marshrutkas (minibusses) zip between cities much faster (and often more frequently) than buses. They cost a little more, but travel much faster and can be hailed anywhere along their route. If you flag down a marshrutka, it's customary to pay on leaving.
Taxis in Tiraspol are very common and are quite cheap. Be wary of scams however--make sure to negotiate a price before you get in the taxi. If you miss the last bus to Kishinev at 18.35, you can take a taxi from Tiraspol to Kishinev, which should not cost more than 30$.
The three official languages of Transdniestria are Russian, Moldovan and Ukrainian, although everybody speaks Russian, and Russian is the language of government.
Some people speak English, German, or even French. After the official languages, English and German are the most common. Young people especially may speak English.
Furthermore, even people who speak some English (or another foreign language) can be quite shy about it, and may deny that they speak it even if they have been educated in it. Keep in mind, there is essentially zero tourism in Transnistria. If you are a native speaker of a foreign language, there's a good chance that you're the first native speaker the person you are talking to has ever spoken with.
Tiraspol does not exactly boast a shopping mile; shops are few and have a limited choice. The official currency is the Transnistrian ruble (which can be used and exchanged only in Transnistria), but most shops and sales stands will accept Moldovan lei and Ukrainian hryvna.
Exchange offices are common and will happily give you Transnistrian rubles in return for just about any tradeable currency. Official exchange rates can be found at the website of the Trans-Dniestr Republican Bank . Don't change more money than you need as trying to turn Transnistrian rubles into other currency may turn out to be difficult - even if exchange booths advertise rates of selling dollars, euro, lei etc. they may not actually be willing to relinquish their stocks of 'real' money. Don't even think about trying to change Transnistian rubles outside Transnistria, no-one will touch them.
There are excellent deals in brandy made locally to a world class standard, about $3 a bottle. Cigarettes are very cheap too. There are also arts and crafts to buy as well. A good exchange point is the Kvint store in downtown Tiraspol--there is an exchange office with good rates right inside the shop. There is also an exchange booth at Tiraspol the bus/train station.
International credit/debit cards and Travel checks are not accepted anywhere in Transnistria. However, there is an international ATM on 25th October Street that dispenses US dollars and Russian Rubles.
There is a large open-air market in Tiraspol, close to the Suvorov's monument, and another in Bendery, located a few meters away from the bus and marshrutkas station. They are probably not fashionable for those looking for something closer to the western style, but interesting to see.
There are several restaurants serving local and international cuisine. There are no western fast food chains but there is an "Andy's Pizza" restaurant on 25th October Street in Tiraspol There are also cafeteria style restaurants which are very cheap usually around US$3-5 for a meal that includes a 3 course lunch along with desert and your choice of drink.
Local wine and cognac are excellent and cheap. The Kvint factory is situated in Tiraspol, and Tiraspol has a Kvint store, offering incredible deals on Kvint products. Kvint produces arguably the best Cognac in the former Soviet Union, but is extremely hard to come by in Western countries (though Moldovan supermarkets will carry it). A trip to Transnistria is not complete without a sample. There is also a soft drink that is sold in the streets called Kvas. For about 50cents you can get a big cold cut of Kvas which is a Russian version of Root Beer. Anyone considering trying it should definately go through with it, it is historic and good.
The physical dangers of Transnistria are almost non-existent. The major cities are much safer than Western European and American cities of similar size and economic makeup. Also, despite the political situation with Moldova, there is essentially no threat of being caught in a military action. There has not been fighting in Transnistria for many years. Indeed, Transnistria is a very safe place for travel. By far the biggest threat to the traveller is scamming.
Despite scare reports, Tiraspol is very welcoming, mainly because it gets so few tourists. Young people speak English and are helpful. The city is well-policed. Street crime is low.
Many Transnistrians are excited to see foreigners and will be very welcoming, if a bit shy at first. Some, however, see foreigners as being sources of easy money. Always negotiate the price of a taxi before you get in. Use pen and paper if you are not a Russian speaker. Ask about the prices of items before you order them at a bar or restaurant. It is not common to be scammed, but it is far from rare. However, even when scams are attempted, it is often for no more than a few euros.
Be wary of police officers. If you look foreign, they will stop and ask to see your passport. Often, they will request bribes, but it should not take more than a few US dollars or euros. This practice is not condoned by the Transnistrian government, but in practice is fairly common. If you speak Russian, the chance to be asked for bribes is much lower.
Some countries, including the United States, fatuously announced travel warnings for their citizens travelling to Transnistria.
Medical care is almost entirely non-existent in Transnistria, especially for non-citizens. Furthermore, even if you have travel health insurance it will often not be valid in Transnistria (but valid in Moldova). It's advisable to check in advance with your insurer.
Be careful in Transnistria's bars during the night. There are often mafia-like characters having a good time with rolls of dollars and you should not inquire too closely about the source of their wealth.
Although internet is available for the locals from home, internet cafes are not widespread yet. There is one in Bendery, in Gagarin Street (close to the city market) and another one in Tiraspol, near Andy's Pizza on 25th October Street. Restaurants 7Пятницъ,"La Placinta" and Andy's Pizza in Tiraspol offer free WiFi (Broadband) for their guests.
