Sark  (French: Sercq; Sercquiais: Sèr or Cerq) is one of the small Channel Islands of Guernsey. Sark is part of the Bailiwick of Guernsey, which in turn is a dependency of the British Crown. It has a population of 600 and an area of 2.1 square miles (5.44 square kilometres).
Sark is part of the Bailiwick of Guernsey, and as such is not a part of the UK, although it relies on it for defence. It participates in the Common Travel Area, but not the European Union. As such, some things will differ from the UK (bank notes, stamps, immigration requirements).
Sark has its own laws and parliament. Sark was once said to be Europe's last remaining feudal fiefdom. In some ways this was true; the Seigneur was lord of the manor, but reforms took place in 2008 and the island's parliament (called Chief Pleas) was gradually democratised. Today, the Chief Pleas is a 30-member chamber with 28 members elected in island-wide elections, in addition to one hereditary member (the Seigneur) and one member (the Seneschal) appointed for life.
There is no airport on Sark, but there is one on Guernsey . Visitors to Sark have to either use a ferry or have access to a sailing boat.
Sark can be reached by a 55 minute ferry ride from Saint Peter Port in Guernsey. There are usually two or more sailings in each direction per day, while in the height of summer this rises to as much as five sailings each way. Expect to pay around £27.80 return per adult. The services are run by Isle of Sark Shipping .
Summer ferries from St. Helier on Jersey (£40.50 day return per adult) and Granville and Carteret in France (€58.50 return per adult, boats stop in St. Helier but you don't have to get off) also operate by Manche Iles Express .
There are public yellow buoy moorings at Havre Gosselin on the west coast and at La Grève de la Ville bay on the east coast, and also anchorages in various bays around the Island. Creux Harbour has toilet facilities and has space for a few boats which are able to dry out, but Maseline Harbour has no visitors' moorings and neither does Les Laches, outside the Creux Harbour. Maseline Harbour jetty is in constant use by ferries, and so it is not possible to remain alongside it.
Cars are not permitted on Sark, but walking around isn't much of a problem as the island is only around two square miles in size.
Horses always have right of way over all other traffic on Sark; be careful as they can be surprisingly quiet, even when drawing a cart, so you may not hear it arrive. Bear in mind that the driver's control of a horse is not absolute.
Tractors are some of the few vehicles permitted on the island; as such, some employed with specially-designed trailers and are used to shuttle visitors up the hill from the quay. Harbour Hill is quite steep, so it may be worth paying the £1 fare to take the "bus" up to the village. If your baggage is labelled (including the name of your accommodation), the hotels and ferry companies organise for dedicated tractors to collect and your bags.
Bicycle hire is available on Sark. Booking in advance is highly recommended during the summer season.
Additionally, some hotels and guest houses have cycles to hire or lend to their guests.
Bear in mind that cycling is illegal on La Coupée and on Harbour Hill.
The other means of transport available are horse-drawn vans. They usually depart from the top of Harbour Hill. They cost about £20 for an hour's drive around Sark, or £15 for a single trip to Little Sark. Prices are per person. The driver will also act as tour guide, and some will speak French.
Sark's predominant official language is English, which is also the native language of most of the population.
Sark has its own dialect of the Norman language called Sercquiais, which is also known as Sarkese or Sark-French (Lé Sèrtchais in the original). The language is descended from, and is closely related to, the Jèrriais language of Jersey. In practice though, the average visitor will only encounter it in place names, as there are only around twenty native speakers.
French is also relatively widely spoken on the island, though it is nowhere near as common as English. For historical reasons, French was until very recently the law used for legal matters, and still is sometimes used in official matters, as the Bailiwick still follows some aspects of Norman law.
The official currency of Sark is the pound sterling (£); Guernsey and Jersey pounds are also accepted locally. Note there are no ATMs on the island, and only one bank, HSBC, open from 9:30 to 15:00 Monday to Friday, which can give money to non-customers. Most hotels and restaurants now have card terminals, and a couple of the grocery stores on the Avenue can do cashback up to £50.
When leaving the Bailiwick of Guernsey (i.e. if you are travelling to Jersey or France), you may purchase duty-free items, usually sold on board ship.
They are a few cafes and two pubs on the islands. The pubs are not allowed to open on Sundays, and alcohol can only be served in cafes on Sundays with purchase of a meal.
Sark now has a smoking ban in pubs, bars and restaurants; it is still legal to smoke in shops, offices, workshops, and places of worship, although many of these places voluntarily enforce smoking bans as well.

As may be expected, the crime rate on Sark is very low (the island only has one policeman). There are no particular health issues either, but it must be noted that private travel insurance should be purchased. Guernsey has no reciprocal agreements with the British NHS or any other Health Service. Any medical treatment must therefore be paid in full. There is a doctor in the west side of the island.
If you are reliant on public transport, you may only go back to Guernsey (and Jersey in the summer). If you have your own boat, you could also go to Alderney, Herm and Lower Normandy in France. You can also reach these destinations from Guernsey; however, in terms of public transport, Sark is pretty much the end of the line. Note that the nearby island of Brecqhou is off-limits as it is the private property of the Barclay twins, British billionaires who own The Spectator and The Telegraph.
