Awesome experience. We got up early and went on the 7 am tour and I would highly recommend doing so. There were very few boats out so we saw a LOT of turtles and it was not crowded with a lot of people. The captain and crew were very sweet and knowledgeable! One of the guides dove down to the bottom and collected some urchins, showed us how to gently hold them, and explained the biological history of how urchins evolved from starfish. Super cool.
