Lac, part of the Bonaire National Marine Park, is the biggest lagoon of the ABC Islands, 700 hectares. Since 1980 Lac has been a RAMSAR site, recognized globally as a wetlands of special significance. The ecosystem of Lac is very fragile. To ensure a proper balance zones have been instituted. Lac is home to three globally endangered species: the Green Turtle, the Queen Conch and the mangrove trees. From north to south, Lac is 3.9 km (not quite 2.5 miles) long, and from east to west 3 km (just under 2 miles). The water surface is approximately 8 square kilometers (3.09 square miles). Lac is bordered by a barrier reef across most of its entrance to the open sea, and lush mangroves just about everywhere else. It has two peninsulas: Cai and Sorobon.
