Often called one of the world's most beautiful beaches, Trunk Bay is a crescent of snow-white sand with a small green islet on the north side of the aquamarine lagoon. Part of the Virgin Islands National Park, Trunk Bay is known for its underwater snorkeling trail. Submerged signs along the trail describe the corals, tropical fish and other marine life found within the bay. Visitors can rent snorkeling gear on the beach, and lifeguards are in attendance.
A postcard-perfect Caribbean beach, Trunk Bay features white powdery sand and is popular with locals and visitors alike. The beach is easily among the most popular across the entire U.S. Virgin Islands. The National Park Service (tiny St. John is primarily composed of National Park Service land) maintains a snorkeling trail at Trunk Bay with underwater signs designed to provide divers with information on marine species.
