This award winning tour offers a unique, multi-eco experience. Kayak among the many small islands that make up St. Thomas' Mangrove Lagoon, including the pristine Cas Cay. This wildlife sanctuary and marine reserve is world famous for its winding, shallow waterways, beautiful mangrove trees with nesting birds, and colorful marine life. Hike and explore Cas Cay! Try your luck with a hermit crab race in a forest with an unusual community of thousands of hermit crabs. An eight minute walk along a level sandy, coral and shell rubble trail leads you to a dramatic area of cliffs with breathtaking views, tidal pools and a rare geologic blowhole. Relax and enjoy the sounds of the splashing water and the beautiful rock and cliff formations. Your guide will show you many new and interesting creatures and unforgettable places.

    We had a great experience. Alonzo was knowledgeable, enthusiastic, and funny. We enjoyed our triple crown tour of kayaking, hiking, and snorkeling. The encounter of hundreds of hermit crabs was at an Indiana Jones level. Steven Spielberg could not have done better. The Death Apple story was captivating and dramatic.

    Amazing experience! Saw some amazing wildlife. Got to kayak out and see some really neat stuff on Cas Cay. Alanzo was extremely knowledgeable about the different wildlife species and the fauna. He spotted everything when we were snorkeling! He even helped my friend who was really struggling with swimming a bit during the snorkel.

  • Alonzo was a kick ass guide!!!

    We booked this excursion through Royal Caribbean during our Eastern Caribbean cruise. It was a highlight of our trip! Our guide, Alonzo, was informative, hilarious, and made our experience 10/10. It wasn’t the best weather but it didn’t even matter, he made our experience so awesome. From the kayaking to the nature walk to the snorkeling, we loved every moment. Thank you Alonzo and Virgin Island Eco Tours!
