An east-coast bay where the reef starts at the shoreline and runs across the whole bay, so it is dived from the beach as well as from boats. The edge of the reef sits between 8 and 15 m, and the bay also holds small caverns, several artificial reef structures and the Katamaran Wreck at 18 m. Turtles and stingrays are regular over the coral.

The dive
The reef here starts at the waterline, which changes how the dive is planned: instead of a descent to find the structure, you swim out over coral that is already under you and let the bottom fall away. The edge of the reef, where the coral gives out, sits between 8 and 15 m, and that band is where most of the dive is spent. Because the reef reaches across the whole bay there is no single route, and the shallow ground on the way back in makes a safety stop almost automatic.
The bay carries more than coral. There are small caverns in the rock, several artificial reef constructions, and the Katamaran Wreck sitting at 18 m, which is the deepest point most groups take in. On the reef itself there is a large field of soft coral alongside a good spread of hard corals and anemones, with sea turtles and stingrays both seen regularly, so a slow first half over the coral and a look at the structures on the way back covers the site well.
