didn't know about the waiver. would be helpful if you notified beforehand. snorkeling could have been a bit better
It was such a fun activity! We learned so much about the island plants and animals in that area. Our guide was knowledgeable and friendly. We had an excellent experience snorkeling which gave me confidence to do it more on the beaches. The trip was beautiful and worth doing again. I felt well taken care of and grateful for the pictures they took along the way.
