Along the south coast of Tobago are three dives sites. From east to west, they are Cove Reef, Flying Reef and Stingray Alley. Coral reefs in this area are gently sloping and exposed to high currents. These are the haunts of large schools of reef fish including grunts and chub.
Iguana Bay is located north of Charlotteville and can only be accessed by boat. Although there are coral communities, there is little structure, likely because of the exposed wave environment. It is home to some colonies of the incredible rare Acropora cervicornis.
Just off Plymouth Point (adjacent to the Plymouth recreational grounds), this well-developed spur and groove reef is dominant in sea plumes and sea rods.
The reef fringes the eastern margins of Castara Bay extending from Heavenly Bay out of the bay. Castara reef is a popular for snorkelling with the rare branching Elkhorn corals close to the rocks. For divers, the reef is dominant in soft coral plumes that make perfect hiding spots for juvenile turtles.
On the eastern side of Man-O-War Bay, this reef is accessible only by boat. The rocky shoreline extends underwater to house branching and bouldering corals on submerged rocks and abundant fish life seeking refuge between the reef and the rocks.
Pirates Bay reefs consist of two small patch reefs located on either side of Pirates Bay in Man-O-War Bay, Charlotteville. This shallow coral community grows over sunken rocks. The reef is home to encrusting fire coral and hard corals, numerous long-spined sea urchins and sea rods. Many reef fish and juvenile marine turtles visit these reefs.
