Customer Reviews

Had the pleasure of doing the excursion with Alonso. He was very informative and an excellent guide. We started off kayaking, made our way to Cas Cay, hiked the island, and then went snorkeling where we saw a wide variety of fish. Learned a lot about the plants, wildlife, and the area. Highly recommend Virgin Islands Eco Tours.

Rented Kayaks for a half day. Beautiful mangroves and and staff gave us great info yo find great spot on Cass Cay to have a picnic with the Hermit Crabs. Kelly was super helpful and very accommodating definitely great way to spend your island time, and the kayaking isn’t difficult

Perfect for those who like to kayak because it can be harder work depending on the wind. This is definitely meant for those who like history and learning about the ecosystem, too. The guides were very knowledgeable and even gave a lot of good recommendations around the island. We had Kade who made it the best and Brooke was awesome too. Wear clothes you don’t mind getting soaked and BRING WATER SHOES!!
