YES! Highly recommend

I had an amazing time! Our guide shared a lot of information about the mangrove. I saw a plethora of different fish and coral. The trip was not physically intensive. In fact. It was very peaceful. You will not believe just how clear the water is ... amazing!
Good overall tour.

Very good tour overall. Kayaked to a small island, looked for sea life along way. On island saw lots of hermit crabs and went to the blowhole to take pictures. Finished with a 30min snorkel, saw tropical fish, barracuda, and a octopus and eel. Guide was helpful and informative. Tour mentions a snack, but it was just water and chocolate.

Definitely cool tour

It was awesome. Only thing I would recommend. Is for the guide to make sure everyone is ok kayaking during the tour. If it wasn't for one of our group members staying behind. We would of been left out there. Until someone realized we weren't behind them.
Fun fun fin!

Our Tour Guide Kevin was wonderful and had great knowledge about the mangroves and the island. We saw a lot of neat sea critters while kayaking to Cas Cay. When we arrived we went on an easy walk through hermit crab utopia where we raced the hermit crabs before walking on to the blow hole which was fun to see and followed by snorkeling. Highly recommend!

Awesome experience

Great shoulder/arm workout:-). Our guide was very friendly and knowledgeable. The lagoon was beautiful. Hike on Cas Cay was beautiful as well and great to learn about the ecosystem. I'm not a big snorkeler, but others very much enjoyed. Plenty of water was provided. Awesome experience. If you like an active experience.... This is a must do.

Our guide Cooper was amazing! He was extremely knowledgeable and wonderful with the kids in our group. He also gave some great recommendations for food and places on St John.
