RhWeekley

We had such a great time on this kayak and snorkel adventure. We got great info on the mangroves, our guide gave us up-close encounters with several different sea creatures, and we got a great first snorkeling experience for our two young girls (8 & 10). Our guide, Connor, was flat-out spectacular. ★★★★★

Anonymous

Our guides Kevin, Connor, and Akeem were extremely helpful with getting everyone into their kayaks and out on the water. Their knowledge was great, and the stories they told made for a fantastic kayak and snorkel tour. ★★★★★

Andrea I.

Our family likes to nerd out with facts, and Jvante was full of great info for us to learn all about the island and its ecosystem. I was having some anxiety about snorkeling as I am not a great swimmer. I wore my life jacket the whole time I snorkeled and was able to see quite a lot and had no anxiety once we got going. ★★★★★

Grant S.

We saw lobsters, lionfish, an upside-down jellyfish, barracuda, and even a reef shark. Slim was an awesome guide, pointing out lots of marine life along the way. It was an awesome experience. ★★★★★

Davion B.

Had an amazing time! The views were great, all the staff were very friendly, and it was worth every penny. ★★★★★

Seaside

Kyrell was an awesome guide for our party of three athletic ladies in their sixties. He guided us through the mangroves and to the beach while pointing out wildlife and the background of the grove. Highly recommend this tour if you want personal attention. ★★★★★
