The experience overall was great. Riding on the boat was one of my favorite things and that wasn’t even the main part. Variety of fish to see and cool lava caves. We even saw a sea turtle. If you are on time you’re late is my best advice. Check in early and make sure you have time before departure.

It was fun being on the fast boat. Plenty of time to snorkel. The snorkeling was incredible. And a little interesting history of some the lava tubes that led into the ocean on the return trip
