No visit to St. Croix is complete without experiencing the beauty of Buck Island Reef National Monument, the Caribbean’s first underwater national park. Caribbean Sea Adventures offers daily half-day and full-day Buck Island excursions, giving you the chance to explore its clear turquoise waters, beautiful beaches and remarkable coral reef ecosystem.

Snorkel along Buck Island’s famous underwater trail and discover colorful coral, tropical fish and other marine life, or spend time relaxing on the beach of this pristine, uninhabited island. National Geographic has recognized Buck Island as one of the world’s best beaches, and it’s easy to see why once you’re there.

Choose from a variety of boats and experiences to make your Buck Island trip your own. Comfortable snorkeling boats provide easy access to the water, while sailing catamarans offer a more relaxed way to reach the island. For a private experience, charter a boat for your group and customize your day with snorkeling, swimming, beach time and sightseeing.

Caribbean Sea Adventures has six vessels to choose from, including the luxurious Celebration, a 41-foot tour boat with comfortable seating, a full bathroom, freshwater shower, boarding stairs and bar. Smooth Recovery, with twin 300 HP outboards, is available exclusively for private groups of up to six guests. Wave Dancer and Inconceivable offer spacious catamaran sailing, while Betty Ann and Mile Mark are designed for easy access to the water and snorkeling.

With US Coast Guard-licensed captains and a team with 167 years of combined experience at Buck Island, Caribbean Sea Adventures knows how to make the most of your time on the water.

Whether you’re visiting for the day or looking for a private island adventure, a Buck Island trip is one of the best ways to experience St. Croix.
