At your first stop, Turtle Beach (“one of the world’s best beaches” according to National Geographic), you’ll get a snorkeling lesson with all the tips and tricks from your expert crew, plus time to relax, sunbathe, swim or enjoy the wildlife. Next, you’ll visit the underwater snorkel trail for a guided tour with your crew, followed by free time to explore: about an hour of snorkeling. This half day trip is great if you want to see Buck Island and fit in another adventure on St. Croix the same day.

Cancel 48 hours or more before your trip for a 100% refund, or within 48 hours for a 50% refund. Day-of cancellations and no-shows aren’t refunded. Our office closes at 5 pm, so a cancellation after hours the day before counts as day-of.
