Off the shores of the stunning island of St. John, Henley Cay is a short boat ride but seems worlds away. Comprised of 11 isles, its crystal clear turquoise waters make it a draw for water activities such as snorkeling and kayaking. Much of the reef is located in shallow water (from 3 to 15 feet,) so visibility is often best just off the shore. Though it has a history dating back to the 18th century, it’s uninhabited today.
Its bay and cove are protected and receive fewer visitors than other snorkel spots on the island. Colorful corals, sea fans, and tropical fish are easily seen, and many consider the snorkeling at Henley Cay to be world-class. Angelfish, parrotfish, surgeonfish, and wrasse are a few of the common fish species spotted often. Tours of the cay typically leave from Caneel Bay and combine kayaking and snorkeling the reefs.
