Charter a private catamaran with a local captain to reach secluded coves off St. Thomas for snorkeling in uncrowded, crystalline water.
What to expect
Your captain picks you up near the pier and sails to a handpicked reef or cove based on conditions that day. Snorkel gear, rum punch, and light island fare are typically included. You'll have full run of the deck for sunbathing between swims, and the crew tailors timing to your group's pace rather than a fixed itinerary.

Good to know
Reserve at least a few weeks ahead in high season; confirm a return time that leaves at least 90 minutes of buffer before all-aboard.
