5.00On a short visit to St Thomas I couldn’t see myself going home without kayaking, hiking and a maiden voyage in snorkeling - this pkg was perfect. Our guide Jonathon was super - would def recommend EcoTours.

5.00Awesome experience. Jesse, Brooke and Alonzo kept everyone safe and together, having a running commentary throughout about the ecosystem in St. Thomas. First we kayaked, then a small hike in the mangroves to see the hermit crabs and the geological hole where the waves crash, and capped it off with snorkeling- the guides will point out all the marine life. They have ample lockers and changing rooms for everyone. Definitely recommend for a day at St. Thomas.
Rememberable!!!

5.00The guide we had was the best. He was dedicated to what he does. Watched over everyone in the group with consideration. The facility was more minimalistic than expected, but definitely adequate for what they do. We enjoyed the kayaking, being outdoors. The snorkeling didn’t provide a great deal to see, but that isn’t the facilities fault. The guide found barracuda, and conch shells to show everyone. Group was great.
Fun trip for the family!!
