So much fun!!! - This was such a cool experience! Every single guide and helper was super nice and conversed with everyone. They let us hold jelly fish, conchs, sea urchins and pointed out a ton of fish while snorkeling. This is a must do excursion!

Hidden Island Wonders: The Cas Cay Adventure of a Lifetime - An unforgettable adventure! We had an incredible time on the Cas Cay Kayak, Hike, and Snorkel Adventure. Kayaking to a gorgeous private island was such a thrill, and exploring the island was even better we saw a poisonous manchineel tree, countless hermit crabs, and even dramatic blow holes spraying water up from the rocks. The snorkeling was spectacular, with crystal-clear water and vibrant marine life like barracudas, sea urchins, and a stingray. We got to feel the jellyfish and sea urchins. Our guides were truly amazing, knowledgeable, friendly, and made the whole experience fun and safe. Highly recommend this tour if you’re looking for a perfect mix of adventure and nature!

Amazing experience! - The overall trip was amazing! It was incredibly fun, the views were great, and definitely full of adventure. The kayaking was a little bit of a workout:) but it was worth it because everything was very pretty. The hike was great and the snorkeling was awesome. Our guide, Devlin(Swish), was hilarious, funny, friendly, helpful, and informative about any questions we had!

Kayak, snorkeling and hike excursion St Thomas/Cas-Cay on July 2, 2025 - Kayaking was fun. Not much to see snorkeling. Organizers should recommend wearing shoes for the trail walk. It would have been treacherous without shoes. photo op at end of trail walk was beautiful. Luckily our guide had his camera so he took pictures and sent them to those of us who requested it.

Not terrible, but wouldn’t do it again. - It was just ok. The hike was more like a leisurely walk. Snorkel was meh and there definitely was almost no wild life or coral. Tour guides were nice and friendly. Definitely overpriced for what it was.

We got to the excursion... - We got to the excursion late because of our cruise ship and they were accommodating for that, but because we were late, we didn’t get scuba gear or anything. Our guide kaz was very condescending to everyone and we didn’t care for him at all. He didn’t recognize that there were older people that couldn’t go as fast.

Very disappointing Experience. - I booked this tour based on the reviews and we were very disappointed. The tour was 90% kayaking. The snorkeling was very bad in murky waters. It was not organized. The employees at checkin were rude. The description says they provide snacks. Snacks included a miniature snickers or kit kat bar. We only had one day in St. Thomas and we were very disappointed by this tour and the company.
