Sandy Cay is a small uninhabited island about 1.5 km east of Jost Van Dyke, protected as a national park. A trail loops around the island through dry scrub forest in about 20 minutes, and the beaches — particularly on the northwest — are excellent for snorkelling over healthy coral. The water is very clear and the reef supports good fish life.
Most visitors arrive by dinghy from an anchored yacht or arrange a water taxi from Great Harbour. There are no facilities on the island — no shade structures, no fresh water, no rubbish bins. Bring what you need and take everything back. The lack of development is the point.
