Very Enjoyable and Memorable. A good value. - 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! - 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!
