  • Awesome St Thomas Tour with the most Amazing Guides

    We had an amazing experience on this tour with Virgin Island Eco Tours. We did the Cas Cay Kayaking, Hike and Snorkel Adventure and loved it! The guides were super knowledgeable and great at interacting with everyone in our small group. The snorkeling was definitely the highlight for us. The only downside would be the lack of corals but that seems to be everywhere now with all of the die off that has happened. We did get to see a crazy amount of beautiful and colorful fish while snorkeling. I highly recommend this tour in St Thomas and would not hesitate to book again in the future.

    My partner and I had an amazing experience!!! Tour guides are funny, knowledgeable, and great advocates for ocean life. You get so much bang for your buck - but I don't want to spoil too much. Bring water safe hiking boots! We were able to walk on the rocks with ease in them.

    Tyrell and Perez were awesome!! We got to go kayaking through mangroves, snorkeling through very clear water and the hike was amazing too. Along the way we saw starfish, rays, jellyfish, large fish, schools of fish, and sea urchins! We got to touch and hold a lot of the animals, the pictures and videos we got were great! We had a hermit crab race! The guides were amazing and went above and beyond to make the experience enjoyable. Would recommend this to anyone to enjoy!
