5.00Liber, Carolyn and Captain Rick led a great snorkel trip! They prepared us for our snorkel adventure and the reef spoke for itself in the beauty and variety of fish! The crew and staff were very friendly and helpful. I highly recommend a wetsuit rental, which is an extra fee.
Nice experience

4.00Nice experience, nice trip and nice crew. Not too many fish at the reef but all good. Tip for the owner. Buy new wetsuits. You let your guests pay for it but most of them are old and broken (especially the ones for the kids) and don't do their job anymore.
I recommend doing this...

5.00I recommend doing this activity during warmer months. My husband and I came in February and the water was so cold it was hard to swim or breathe. But we are definitely coming back during the summer! The staff was very friendly 10/10 easy to follow instructions at the boat and when checking in. The captain and livir are the best! Overall unforgettable experience. Highly recommended!

4.00We had a good time on this tour in spite of the brisk temperature. The management was helpful , and offered us wetsuits to rent for $10, which was an excellent option.
Fun trip to the Grecian Reef, which is a great shallow water reef with lots of fish and coral.

5.00We had a really nice snorkel tour. The boat was tidy and the equipment was well maintained. We saw the crew bleaching the equipment getting it ready for future users. The crew, Liber, Justice and Captain Rick were very safety minded and fun. The water was a little choppy, but it was clear and we saw some amazing fish. We definitely recommend this tour.
