The Tobago Cays are an archipelago located in the Southern Grenadines of Saint Vincent and the Grenadines comprising five small islands and extensive coral reefs. The cays – Petit Rameau, Petit Bateau, Baradal, Petit Tabac and Jamesby – are a popular tourism destination.
The Tobago Cays are now the key element of the Tobago Cays Marine Park, run and owned by the Saint Vincent and the Grenadines government. The marine park consists of a 1,400-acre (5.7 km²) sand-bottom lagoon which encompasses the five cays, the inhabited island of Mayreau and the 4 km Horseshoe Reef. The marine park was listed as a regionally significant ecosystem under the SPAW (Specially Protected Areas and Wildlife) Protocol in December 2014. The most extensive and well-developed coral reef complexes in Saint Vincent and the Grenadines occur on shallow shelves around the windward sides of Mayreau and Union islands and the cays themselves. In addition, principal vegetation types include beach vegetation and dry forest. With the exception of a small mangrove in Petit Rameau and salt pond in Mayreau, there are no wetlands in the cays.
The TCMP is governed by a Marine Parks Board, which contains ten members, including a chairperson and vice-chairperson. The ten members are two NGO representative, on nominee of the SVG National Trust, one nominee of the Hotel and Tourism Association, one nominee of the Minister of Tourism, one nominee of the Minister for Parks, the Chief Fisheries Officer, the Director of Finance (or nominee), the Solicitor General (or nominee) and the Commander of the Coast Guard (or nominee). There are 13 staff working at the Marine Park Authority in Union Island. The authority is self-financed (from fees), it does not rely on government subventions. The Park Manager runs the operations of the TCMP, with a number of rangers, wardens, office attendants and administrative assistants. There is a total of 13 staff. The Tobago Cays Marine Park offices are located at Clifton harbour, Union Island. Coral reefs are protected by a series of regulations which specify areas to anchor and windsurf, and prohibit fishing within most of the park. There are also measures to reduce the likelihood of coral damage from boats including speed restrictions and buoys setting out sailing areas. Regulations prevent waste dumping. Diving is limited to registered local dive shops. The flora or fauna is not allowed to be touched, and the substrate is not to be disturbed. Sea grass beds are protected by a series of regulations which specify areas to anchor, and prohibit fishing within most of the park. There is a specific sea grass conservation area which is off limits to boats, although swimming and snorkelling is allowed.
Tourism is the main activity within the marine park. Around 8000 yachts visit the cays each year, which includes many charter yachts, and day trips. Snorkelling and scuba diving is a popular activity within the park, there are four local dive shops in the surrounding islands – the most popular sites for scuba diving are Mayreau Gardens, Horseshoe Reef and World’s End Reef. Cruise ships visit the park mainly in the high season from November to April. Visitors also use water taxis to visit the cays for a day trip, there are around 40 taxis in Union and 5–10 in Mayreau. There are a number of vendors in the park, selling T-shirts, handicrafts, ice, bread, fresh fish, fruits and vegetables to the visiting yachts. Vendors are restricted to the north beach of Petit Bateau. Wind surfing also occurs in the park. Hotels and restaurants in the surrounding islands are dependent on the park for drawing tourists to the area.
