Let's go on this trip again

Aqua Marine Dive Center gave us the best snorkel experience so far! Their friendly demeanor, knowledge of fish, and sense of adventure was outstanding. It was a great day, and we got some amazing photos of the fish. We recommend this adventure!

Great first time diving experience

Awesome crew with great instructors. I was a first dime scuba diver and felt safe and comfortable the whole time. The instructors are patient, knowledgeable and very helpful.

Excellent Refresher Course

Excellent dive experience with Aqua Marine dive center. Couple of years absent from diving and Tommy gave an excellent refresher course and got me back underwater and swimming with the fishes with confidence again. Great team from the office Mich to the boat captain Steve.

Best day of our entire trip! We saw so many fish and the coral was beautiful. Jess, Tommy, and Steve were all so nice and gave us great info about the area. Jess was the snorkel guide and she pointed out and named all the fish as we went along. My kids and I loved it so much we booked with them again the next day!

Great Dive Operation

This is a great dive operation. Crew and owners are terrific people that want you to have a good safe experience. Boat is very nice and the equipment top notch. Dive bottom time was generous.
