Great experience. Got the outfit here, off of TripAdvisors and am so glad we came to this platform! Alex, Nick, and Anders made a great trio, serving 25 of us on an pm trip to snorkel with the turtles...which we did! Great "PainKillers" serves on the way back, too!

Incredible experience! The staff is so welcoming. The turtles were easy to find! We saw more than 6 while we were in the water. The reef is small, but lots of different fish. Highly recommend! Free Pain Killers (alcoholic beverage) for the ride back was a nice bonus

Wow! Had the best day ever with my fiance and friends for a 30th birthday. Tim, Portia, and captain Serena were go efficient getting everyone on board and the rules out of the way so that the whole trip ran seamlessly! The weather was amazing and the crew was so fun, conversational, and knowledgeable! We saw 5 sea turtles, the coral reef with TONS of different fish, and even a spotted eagle ray!!! drinks and snacks followed on the way home and it was a blast. there’s a beach you can visit after the boat day if you’re not too tired from such an awesome time! 10/10 would do again.

My wife and I went on this excursion and had a great time. I will say that the 1p time slot that we went on seemed better (in hindsight) because the folks from the cruise ships had all been on the morning excursion. This meant that there were only about 11 folks on our boat. Tim, Isaac, and Serena (the crew members) were so nice and lightheaded that it made the trip even more memorable. The sea turtles were a treat and Tim, the snorkeling guide, was awesome.

Had an amazing experience over Thanksgiving week. We got the opportunity to go on a snorkeling adventure with castaway girl catamaran. The crew was amazing, and the adventure was everything we had expected. Their team went above and beyond to make our experience amazing. We will definitely go back and hope we get the same crew again. Y’all were amazing thank you.

Amazing tour with approx. one hour of snorkeling with an amazing crew. My family really enjoyed the boat and the views. When we went snorkeling, the crew made sure that we were safe and knew everything before we got into the water. The tour was around 20 minutes and then, you can go explore on your own within the perimeter. Recommend it 100% to everyone!
