Captain and crew are very cool. Very respectful of the sea turtles. They want you to have a good time while respecting the wildlife. The turtles will come up for air and get right in your face so you have to move around them. Would not suggest for weaker swimmers as there are currents and waves and you need to be able to move around people and turtles. Life vest required. Show up early, respect the sea and wildlife, and have fun!
