Caribbean Sea Adventures, St. Croix

Parasailing / Paragliding · Fishing Charter / Tour
We love the sun, sand, and sea! We offer public and private charters, sunset sails, snorkeling, scuba diving, and wedding ceremonies at beautiful Buck Island Reef National Monument. With 6 unique boats to choose from, Caribbean Sea Adventures has something for everyone. Specialising in private and small group charters so you never need to worry about personal space. We limit our public excursions to 80% of each vessel’s U.S. Coast Guard capacity ensuring that our guests never miss out on the personal attention our crew has become famous for.

Buck Island Reef National Monument is a must for every visitor whether you snorkel the underwater trail or just enjoy the beach! Proclaimed as a National Monument in 1961 by John F. Kennedy, Buck Island is considered to be "one of the finest marine gardens in the Caribbean Sea." Buck Island's main beauty lies in the surrounding coral reef ecosystem and its unique underwater trail. Here you will snorkel amongst endangered elkhorn and staghorn coral formations teeming with colorful reef fish. After snorkeling, we head to Turtle Beach on the west side of Buck Island for some rest and relaxation. Turtle beach was rated one of the world's most beautiful beaches by National Geographic!

You can sign-up for a full or half day charter on either a power or sail boat, any day of the week!
