Diamond Cay (Jost Van Dyke) — Diamond Cay, declared a national park in 1991, is located off Long Bay, Jost Van Dyke. Like most other islands that have been declared National Parks, Diamond Cay is a bird sanctuary. The 1.25 acre nesting site is home to several species of bird, including tern, boobies, and pelicans. The island is part of a proposed protected area, which includes the privately owned islands of Sandy Cay, Sandy Spit, a portion of Little Jost Van Dyke, and the surrounding marine area. The endangered leatherback turtle nests on Sandy Cay. Two species of lizard live on Sandy Spit. The volcanic nature of the island is more pronounced on the windward side, with bare, rocky cliffs, while the leeward side is lined with sandy beaches. The area has several day anchorages close to vibrant reefs, for snorkeling, and a hiking trail on Sandy Cay. Boaters should be cautious and conscientious about anchoring in sand only to avoid damaging the reefs.
