until 2002, tourism was virtually non-existent because of the inaccessibility of the island to transport, the absence of guest accommodation and the need for a sponsor. limited air travel has, however, been made available in recent years to the public by the raf, and the georgetown obsidian hotel and a number of guest cottages have been opened. all visitors are required to obtain an entry permit before travelling. sport fishing is the main attraction for many of the visitors. the island also boasts what is sometimes called the worst golf course in the world.
