Site description Lac Bay on the southeastern side of the island is a shallow bay protected from the open ocean by a fringing reef at its mouth. The only significant mangrove habitat (about 100 ha) on the island is located here. A small resort and two windsurfing centres are located on the south side of the bay and there is a small harbor for small fishing vessels (that fish outside of the bay) with a set of buildings and a bar/restaurant on the north side of the mouth of the bay. Scattered farms and homes ring the edge in the northwest corner of the IBA. The bay has become popular for a variety of recreational watersports (jet-skis and kite-surfing are banned) and for guided naturalist kayak trips among the mangroves.
