Little Water Cay is an island of approximately 116.2 acres, northeast of the Leeward area of Providenciales, Turks & Caicos Islands. It is a low-lying former island. It is a very important wildlife habitat, particularly for the endangered endemic Turks and Caicos Rock Iguana (Cyclura carinata).

Nature lovers can observe several habitats on the cay, including mangrove and buttonwood communities, hyper-saline and tidal flat areas, coastal coppice, and coastal scrub. In addition to our diverse flora visitors can spot a good range of birds typical of coastal habitats such as Osprey, Brown Pelicans, several species of shorebird and Bananaquits.

Hermit crab are commonly seen after rain. Southern stingrays are commonly seen on the south shore sand flats. Lemon sharks prefer moderately deep tropical waters such as the water surrounding Little Water Cay.

Little Water Cay is a key site for the endangered endemic Turks and Caicos Islands Rock Iguana and an excellent eco-tour site for families.
