We are "seniors" and tried snorkeling for the first time with Kai and Amanda. We had a great time. Kai and Amanda were knowledgable, capable, and caring. We visited two bays, saw beautiful fish, saw whales spouting and diving, saw caves and lava tubes, saw Captain Cook's statue, and had fresh fruits and drinks along the way. Seniors note: we used noodles to keep us afloat and make it less tiring. We recommend this trip.
