Tobago Cays: Horseshoe Reef, Sea Turtles and the Iconic Lagoon of the Grenadines

The Tobago Cays are the defining yacht charter destination of St. Vincent and the Grenadines, a spectacular collection of five uninhabited islands surrounded by coral reefs, white-sand beaches and some of the clearest turquoise water in the Caribbean. Located immediately east of Mayreau, the cays form the heart of the Tobago Cays Marine Park and offer one of the most extraordinary natural anchorages anywhere in the Grenadines.

Four of the islands, Petit Rameau, Petit Bateau, Baradal and Jamesby, sit behind the enormous Horseshoe Reef, which curves around the eastern side of the lagoon and protects anchored yachts from much of the Atlantic swell. Petit Tabac lies farther east outside the main reef system, while World's End Reef and Egg Reef extend into the surrounding ocean. From the deck of a yacht, the result is an almost surreal landscape of shallow aquamarine lagoons, coral gardens and tiny green islands surrounded by open sea.

Marine life is central to the experience. Green turtles graze through the seagrass around Baradal, tropical fish gather along Horseshoe Reef, and rays can be encountered around the outer reefs. Snorkeling, scuba diving, paddleboarding and swimming are therefore as important here as simply relaxing aboard the yacht. The Tobago Cays are also deeply associated with sailing itself, offering the kind of remote, boat-accessed environment that has made the Grenadines one of the world's classic yacht charter destinations.

Approaching the Tobago Cays requires considerably more care than entering a conventional harbor. Extensive coral reefs, shallow water and isolated coral heads surround the islands, so good daylight, current charts and careful visual navigation are essential. Horseshoe Reef provides remarkable protection once inside the main lagoon, but captains must use the established approaches rather than attempting shortcuts across reef areas.

The Marine Park also imposes specific navigation and conservation rules. Vessels must not exceed five knots, and yachts must avoid coral and seagrass when anchoring. Moorings should be used where provided, while any permitted anchoring must be on suitable sandy seabed. Fishing, removing marine life and discharging wastewater are prohibited throughout the protected area.

Petit Tabac requires particular attention. Although it was previously used as an anchoring destination, current cruising information updated in April 2026 confirms that all yacht anchoring around Petit Tabac is now prohibited because of coral damage. The island should therefore be visited by tender or water taxi according to current park arrangements rather than by independently anchoring a yacht beside it.

The main lagoon behind Horseshoe Reef contains the principal yacht mooring and anchoring areas. Approximately 30 managed moorings are available according to current 2026 cruising information, positioned partly to reduce anchor damage around sensitive turtle and coral habitats. Moorings are managed by Tobago Cays Marine Park rangers, and both marine park entry charges and overnight mooring fees apply.

Anchoring remains permitted in designated sandy areas of the main lagoon, but yachts must stay clear of coral and seagrass beds. Seagrass is particularly important around the Cays because juvenile green turtles use these areas for feeding. Anchoring currently attracts the same overnight park charge as using a mooring, so there is little financial reason to choose anchoring over a properly positioned park mooring when one is available.

Another possible anchoring position lies in the cut between Petit Rameau and Petit Bateau, where cruising guidance reports good holding but also a strong current. Bow and stern anchors may be required there depending on conditions. Regardless of location, crews should inspect any mooring before relying on it and follow instructions from Marine Park rangers.

The Tobago Cays Marine Park was established in 1998 and protects the five principal uninhabited islands together with coral reefs, seagrass beds, lagoons and surrounding marine habitat. Baradal's southwestern waters contain a designated turtle-watching reserve where green turtles can frequently be observed feeding in the wild.

Petit Tabac provides the Cays with another famous connection. The tiny palm-covered island was used as a filming location for Pirates of the Caribbean: The Curse of the Black Pearl, appearing as the deserted island where Jack Sparrow and Elizabeth Swann are stranded. Today, however, the real stars of the Tobago Cays remain the reefs, turtles and extraordinary marine landscape surrounding the islands.
