A visit to Little Water Cay offers the best chance of spotting the endangered Turks and Caicos rock iguanas that were once prolific throughout the islands. Local conservation efforts at this small islet have helped revive their population. Two boardwalks allow visitors to take an easy stroll and look for the lizards. You can visit Little Water Cay as part of an organized boat trip, or simply rent a kayak and paddle there from the Leeward Marina area on Providenciales. There is a visitor center on the island where you can pay the admission fee.
