Caribbean Sea Adventures

Caribbean Sea Adventures is a boat tour company with an office on King Street in Christiansted, St. Croix. Its main trips go to Buck Island Reef National Monument: a half-day cruise that always leaves from Christiansted harbor, and a full-day sail that the company says moves its departures to Green Cay Marina starting November 1, 2026. It also runs sunset cruises and private charters, many of which leave from Green Cay Marina, and it books parasailing and fishing charters that partner operators run under their own terms. Trips can be booked online with live availability, or by phone or email, and the office is open every day. Because departure points differ from trip to trip, confirm where your boat leaves from when you book, and ask what the trip includes and what happens if the weather cancels it.
