The Tobago Cays Marine Park (TCMP), located in St. Vincent and the Grenadines, houses a series of globally significant habitats including coral reefs, sea turtle nesting sites and feeding areas, and small systems of mangroves. The marine portion of the park surrounds five uninhabited cays, the populated island of Mayreau, and three islets. The four-kilometer long Horseshoe Reef, the longest of the four main reef systems in the TCMP, encloses four of the cays (Petit Bateau, Petit Rameau, Baradal, and Jamesby) with the fifth cay (Petit Tabac) lying just outside the reef to the east.The Tobago Cays are known as the “Jewel in the Crown” of the Southern Grenadines and are of significant economic, cultural, social, and environmental value to St. Vincent and the Grenadines.
