Fort George Cay is home to the remnants of an 18th-century British-built fort. Now the only invaders are divers and snorkelers there to inspect the gun emplacements slowly becoming one with the sea bottom.
Little Water Cay is famous for its population of Turks and Caicos rock iguanas, which used to be common on the islands, but now thrive only here, thanks to conservation initiatives. Admission to the nature reserve on 'Iguana Island' is charged at the visitor centre. Visitors must stay on the boardwalks and refrain from touching or feeding the iguanas.
French Cay, south of Providenciales, is an old pirate hideaway now frequented by migrating birds. Just offshore the waters are teeming with stingrays. Nurse sharks gather here in summer.
Parrot Cay is home to one of the Caribbean's most luxurious and exclusive resorts, the eponymous Parrot Cay.
