Caneel Bay is just one of several possibilities for this trip and not always a definite stop ( time and weather dependent).

We had an incredible time on our private sail and snorkel tour in St. Thomas. The crew was friendly, knowledgeable, and made the entire experience relaxing and fun from start to finish. The snorkeling spots were beautiful with crystal clear water and amazing marine life. The boat was clean, comfortable, and never felt crowded like some of the other boating experiences around the island. It was one of the highlights of our vacation and we would absolutely do it again!

This experience was extraordinary! The guides were amazing, sailing was really enjoyable and the location to snorkel gave us wonderful opportunities to see the turtles, rays, and fish!

After a scheduling shuffle, we ended up doing this as our first activity of our trip. We had never been on a sailboat before, so we were looking forward to that as much as the snorkeling. Rob & Deb were the perfect captain/hosts, and everything was just so relaxing. We snorkeled at Christmas Cove. We never saw the elusive octopus. Maybe next time. It was a perfect day to make incredible memories! Thanks! - Mark & Tricia

It was out first time on a sail boat and it was fun. I wasn't sure of the tilting of the ship but our hosts were so casual about it that I felt at ease. The hosts were warm, conversations good, and the spot they picked had a large variety of sea life. We enjoyed the snorkeling, the current was relaxing and calm. Weather was perfect.

Your experience begins with a scenic sailing adventure of about an hour, offering incredible views of the surrounding islands. From there, you’ll stop to snorkel at a secluded island, where you can spot sea turtles and a wide variety of colorful fish. After snorkeling, sit back, relax, and enjoy the peaceful sail back.

This was so fun! My husband wasn’t feeling well at one point but Rob and Deb took amazing care of him. Made sure he had water at all times, also made sure everyone on the boat had what they needed. The hospitality was unmatched! Deb constantly filled our cups up with whatever drink we wanted, she offered us snacks after snorkeling too! Rob gave us some good dinner recs and told us some good info about the island. We would definitely recommend this to anyone!
