I really lucked out on this excursion. I arrived at the pick-up location early and was concerned when I was told by a cab dispatcher that they might not show for one person. I was later joined by a couple, and we were taken to the starting location. We had only 3 of us plus Sabrina for the tour, so it was absolutely amazing. She is extremely knowledgeable and more than happy to share her knowledge. Because of the small group, we had more time to snorkel. We were given the choice of single or double kayaks, so as a solo, there were no concerns. This was the best excursion of my trip!

Was very nice kayaks and snorkeling gear were provided our guide was very personable and informative! The only negative was that it wasn’t a very nice snorkeling spot! Overall it was worth doing!

We really enjoyed this tour with Skylar and the team. Very knowledgeable guides who took us through the mangroves to the island of hermit crabs, there was so many! We walked to where the sea met the rocks, again this was a fantastic photo opportunity. We saw many fish whilst snorkelling including stingray, barracuda, conch and lobster. If you visit St Thomas, definitely take a trip out to these guys. High recommended

We had a fantastic time with the combination of kayaking, snorkeling and also a small hike to Red Point. Our guide Ronnie was amazing. He was very knowledgeable about marine life, biology and the mangroves. We really enjoyed the small group of 8 versus 30 plus on the cruise ship. The small group was like a private tour. We were able to get to Red Point and take tons of photos of the waves crashing on the red rocks and making these wonderful huge splashes before the big cruise ship tour got there. The marine life was amazing to see in the roots of the mangroves and also at the sunken boat with a lot of fish resting there. The frozen chocolates was a special treat from Ronnie that we needed for a great source of energy for the kayak going back. Overall, I would recommend this trip if you prefer the smaller group and like a sense of adventure of kayaking to an island, hiking and seeing nature, snorkeling and kayaking back.

This tour was amazing!

Getting a taxi took us 20 minutes and 25 minutes to get there, so allow enough time if leaving from a cruise ship.
Michael and Richard were great guides! Very informative and willing to answer any questions.
I wish there would have been some place to test the mask out because mine had a smallannoying leak.
The hike was well worth it, we saw a lot of sea life in the tide pools.

We had a wonderful time on this excursion, I had my husband and three adult children with me, and we all had so much fun. The staff was great, and the two guides were awesome. I would suggest this excursion to my family and friends!

We have our own kayak but kayacking in the mangrove lagoon was simply amazing! an unforgettable experience, the tour leader was also very kind and explained in detail.

Great excursion. Jason, our guide, was wonderful. My 10-year old daughter had a million questions, and he was happy to answer all of them. There was a strong current, so the kayaking was harder than I expected, as was the snorkeling. We didn't see too much snorkeling but did find one ray and some fish. The hike was beautiful, and the crabs and blow hole were a big hit. I would definitely recommend this excursion.
