Buck Island Cove is a sheltered natural inlet on St. Thomas, USVI, prized for calm anchorage, rich marine life, and easy access to the island's southeastern shore.
Buck Island Cove occupies a quiet corner of St. Thomas's southeastern coastline, part of a broader network of sheltered bays and inlets that define the Estate Bovoni area. The cove's protected position makes it a natural gathering point for small watercraft, and the surrounding landscape blends low scrub, mangrove fringe, and open water in a way that feels removed from the bustle of Charlotte Amalie just a few miles to the west.
The water quality here draws snorkelers who want a more intimate experience than the island's busier beaches offer. Shallow coral heads and seagrass beds support a variety of reef fish, and the calm surface makes conditions forgiving for paddlers. Joining a kayaking excursion is one of the easiest ways to reach the cove and take in the surrounding coastline at a relaxed pace.
The adjacent Mangrove Lagoon lies just a few kilometers away and forms part of the same protected coastal corridor, making it a natural extension of any visit to Buck Island Cove. Together these sites represent some of the most ecologically intact shoreline remaining on St. Thomas, and that distinction alone makes the trip worthwhile.
Visit in the early morning when the water is glassiest and boat traffic is lightest, giving you the clearest views into the shallows.
Bring a mask and snorkel to explore the fringing reef just below the surface, where parrotfish and sergeant majors are common sightings.
Arrive by kayak or paddleboard from the Estate Bovoni side for the most direct and scenic approach to the cove.
Pack sun protection and plenty of water, as shade is limited once you are out on the water away from the mangrove edges.
Pair a visit with a stop at nearby Mangrove Lagoon to extend your exploration of this protected coastal ecosystem on St. Thomas.
