An amazing experience - What a great experience from the time we walked in the door. All of the staff were very informative and polite. They explained what was included and where we would go! The day of the snorkel trip was just as great. Very well organized and very thorough. From the sign in desk to the boat crew! Captain Rick, Justice and Mackenzie did an amazing job explaining the process, helping everyone with the essentials and just talking of fun local things to do. Free water was provided and you could purchase pop for $1. Overall, we had an amazing time. The snorkel area we went to was just breath taking. The team provided insight of what areas to focus on ! We will be back! We highly recommend this tour!!

Snorkeling adventure - The day started out on the chilly side but the staff and crew reassured us the water temp was perfect. We added on wet suits just for added warmth just in case. Justice, Liber, and the captain of our tour did an amazing job at making sure we were all safe, smiling, laughing and having an all around good time. We didn’t have to swim far from the boat at all to see the reef. Would highly recommend this tour and crew to all that are new to snorkeling! Happy holidays!!

Great experience, highly recommend - Boat staff was super friendly, I got pretty sea sick and they helped me right away. All instructions were very clear and the trip was well organized. It was forecasted to rain, staff made sure everything was safe before we set sail, and in the case of rain we were promised a refund or a reschedule.
