Andrea I.

First of all, our tour guides Jvante and Donovan were awesome! They were very friendly, knowledgeable, and patient with us as beginners. While I have some anxiety about snorkeling as I am not a great swimmer, the water was calm and not too deep. Wearing my life jacket, I felt no anxiety and enjoyed seeing so much marine life. ★★★★★

Andrea B.

This was a fantastic experience! It is always tricky to find a great outdoor adventure with three young boys, but this was amazing! My younger boys played and explored while the older ones snorkeled. Highly recommend ★★★★★

Debbie W.

Our guides, Elvin and Slim, were so knowledgeable about mangroves, sea life, and the history of Cas Cay. They kept an eye out for unusual sea creatures, ensuring everyone got a chance to experience them. ★★★★★

Emily I.

The kayaking wasn’t too physically demanding, and the hike was even easier. Even though it rained, we still saw sharks and barracudas while snorkeling. We never felt unsafe on our 3-hour trip. ★★★★★

Andrea I.

This was our best experience in St. Thomas! The calm mangrove waters made paddling easy, and snorkeling was a great first-time experience for our 12-year-old son. ★★★★★

Davion B.

Had an amazing time! The views were great, the staff was friendly, and it was worth every penny. ★★★★★

Grant S.

The highlight of the tour was snorkeling and getting to hold starfish, conches, and urchins while seeing barracudas and even a reef shark. Truly a once-in-a-lifetime experience! ★★★★★

Frequently Asked Questions

  • What will we see on the tour?

    On our St. Thomas Mangrove Lagoon tours, you will kayak among the many small islands of the unique Inner Mangrove Lagoon. You may see a variety of birds such as brown pelicans, blue herons, night herons, egrets, yellow warblers and hummingbirds. While snorkeling you may see spotted eagle rays, turtles, pufferfish, octopus, lobster, stingrays, parrotfish and much more!

  • Are there any threatening sea creatures in the waters of your tours?

    Consider yourself lucky if you are fortunate enough to see a baby shark or barracuda. For the most part they are more afraid of you than you are of them.

  • I can’t swim. Can I still do your tour?

    Yes! All guests wear life jackets, so you’re guaranteed to float. Relax, kick gently, and you’ll see lots of sea life during the snorkel portion of your tour.

  • I’m not an experienced snorkeler, can I still go?

    Yes! We offer full snorkeling instruction. We also require that every person on the tour wear a life jacket during the kayaking and snorkeling portions of the tour.

  • I’ve never been kayaking before, can I still go?

    Yes! We offer full kayaking instruction before the tour begins. It’s perfect for children, adults, and seniors. Beginners are welcomed!

  • Can my toddlers go on your tours?

    Absolutely! As long as they weigh a minimum of 30 pounds, we can provide them with life jackets. If your child weighs less than that, you will have to bring a suitably sized life jacket for your child to wear.

  • What is your cancellation policy?

    Your payment is 100% refundable until 24 hours before the date and time your tour is due to depart. If you cancel your booking with less than 24 hours notice or fail to show up for your tour, then the full cost of the tour will not be refunded.
