An interesting attraction is the nature reserve of Little Water Cay, locally known as 'Iguana Island'. This small island, or cay, is home to the few remaining Rock Iguanas that used to cover most of the islands in the Turks and Caicos.
Little Water Cay is only 499 yards (456 metres) from Providenciales. It's a short trip via a tour boat or kayak from the Leeward Marina area on Providenciales to the nearby island. Big Blue Unlimited rents kayaks, but be aware of currents in the channel between Providenciales and Little Water Cay. However, due to the presence of boats and other people in the area, there are usually people to assist you if you have problems. Local companies offer package eco-tours which combine a visit to Iguana Island.
The main and only attractions are the Turks and Caicos Rock Iguana (Cyclura carinata), which are basically big lizards. They're everywhere on the island due to extensive conservation efforts. If you're travelling by kayak, be sure to stop by the little islets nearby to see the more wild, smaller iguanas which inhabit these miniscule islands.
Little Water Cay has two sets of loop boardwalks installed, one on the north side and one on the south side of the island. Those kayaking will reaching the southern boardwalk, whereas those arriving by boat depends on the operator and size of the boat. Both boardwalks offer about the same experience, although the northern part of the island is a bit more marshland.
This is something that families, eco-tourist, and just the average person will find interesting. Total trip (if visiting the island only) is about 2-3 hours round trip.
Unfortunately, these animals are classified as endangered. These lizards used to live on all the islands in the Turks and Caicos, but the introduction by humans of cats and dogs quickly led to their rapid decline and extinction on the other islands.
When visiting, DO NOT feed the iguanas and stay on the boardwalks.
