All scheduled international flights into the Turks and Caicos arrive at the Providenciales International Airport (PLS). Domestic flights are offered by two local airlines to the other main islands in the country.
You'll need a valid passport and return/onward ticket to enter the Turks and Caicos Islands. Most nationalities don't need a visa (the United States, Canada and the United Kingdom do not). If you're traveling with pets, you'll need a veterinary certificate stating your animal is in good health. See Passports and Visas and Travelling with Pets for more information.
At this time, all cruise ships arriving in the Turks and Caicos only arrive at Grand Turk. Due to time constraints, it's not feasible to see Providenciales when visiting Grand Turk by cruise ship for a day.
The Turks and Caicos is a popular destination for yachts and pleasure boaters, and there are many marinas throughout the islands. Your initial stop once you arrive in the islands must be at a port-of-entry. There are several on Providenciales and one on Grand Turk and South Caicos. The harbormaster at the port of entry has the authority to grant leave to enter for one-week. If you wish to stay longer or cruise among the islands, you must get a Cruising Permit (valid for 90 days), and/or visit one of the main immigration offices on Providenciales or Grand Turk.
The waters around the Turks and Caicos have many reef and shallows hazards, so proper charts are a necessity for navigating among the Turks and Caicos Islands. The foremost publisher is Waveyline Publishing of Grand Turk, which produces detailed electronic and printed charts of the Turks and Caicos archipelago.
