My guide is Alonso potter. It was fun. He is patient, nice, friendly. He gives us water and snacks. We went on Friday and it is not crowded at all.

My husband and I had the best time at our tour! Our main guide, Alonso, was very knowledgeable and had such a great energy about him. He made the tour so much fun. Jezi and the guy taking the photos were also very sweet!! I would highly recommend taking this tour. A great value for everything we did in 4 hours.

10/10 experience!! If you are looking for a family friendly excursion to explore the best of St. Thomas, this is it. Our guide, Alonzo went above and beyond to make this day fun and adventurous! Our kids are 7 and 10 and had an absolute blast. (Recommend water shoes, but the hike is do-able in sandals). So much fun, would book again!

A must do on the island. Come prepared. The tour guide was very informative and did a great job. Bring your own snorkel and life jackets if you can.
