It was a smooth easy boat ride to three different snorkeling locations. One of the locations we saw sea turtles as well as thousands of fish and other sea life. We stopped a few caves and saw lava tubes, and also a dolphin sighting.

Our whale watching tour was totally successful! We saw several whales in the distance, coming in and out of the water. The captain and mate were so kind and intent on giving us a great adventure. They were successful!
