An incredibly fun boat trip with a great captain. A unique kind of boat with a glass bottom so you could see the turtles swimming beautifully. Dog-friendly!

Great tour at the end of September, although most of the turtles were already migrating, we were able to marvel at one. The swim stops were wonderful.

The scenery was amazing. We even saw a turtle. The skipper was very experienced and had great control of the boat. Top-notch.
