We had an amazing time getting to explore and enjoy all that the beautiful island has to offer. Our guide, Swish, was the perfect mix of professional with that laid back island time vibe. He had great facts about the nature and delivered a unique and unforgettable experience. An extra star to him for the great dad jokes!

Toured the mangrove، hiked the Cay, and snorkled. Saw an awesome array of fish, plus sea urchin, a barracuda, a pin cushion starfish, jellyfish and two octopus. Jonathan was a terrific guide and a wealth of island restaurant recommendations:)
