This was a great experience and well worth the cost. We were even offered and accepted the optional 30 minute nature hike when we called to check-in the previous day. That said, and although it might have been an unusually hectic day, we our group of 6 were shuffled around for over an hour and a half while the busloads of cruise ship passengers were being sorted out and set off with their guides. Since we were staying at a resort on the island I suppose they assumed we could wait - not having to get back to a ship. Even after the cruise ship passengers boarded their kayaks and set out with their guides we were still asked to wait for another group that was supposedly tied up in traffic. In the end it all turned out for the best as the late group never showed up thus affording us a private tour for our group of six. Our guide, John, was very informative and attended to all our needs. He led us out to a great snorkeling spot and identified many of the tropical fish for us. John even extended our kayak trek back to the landing after our snorkel stop. The only advice I would give to others is to book your tour on a day when there are no or few cruise ships in port.

This was the highlight of our cruise! The staff are so welcoming, helpful, and patient! My husband and I had never Kayaked before and it was fun. Snorkeling was a wonderful experience and very easy. The optional hike was easy and quite informational. We would highly recommend this adventure.

The whole tour was excellent--the locations gave us a private and natural experience and the locations for kayaking and then snorkeling were picturesque. The guides were awesome especially Jai who was so upbeat, welcoming hello my beautiful people! and so proud of his island and it's beauty. He spent extra time with the kids in the water and on the crab island where an area of the ground and even trees were covered in red-claw hermit crabs, explaining the creatures we were seeing. We really appreciated his hospitality, do this tour!

I booked this tour not wanting to go, because I have a fear of the ocean and sea creatures. But everyone in my group wanted to do it so I followed along. And I'm SO SO SO glad I did! The kayake adventure is thru the mangroves and does feel like your in the ocean at all, rather a lake or stream.
