5.00Did not know this experience existed! It was so much fun! I am not a swimmer or snorkeler, but I wanted to go underwater to see the fishes and this experience gave me the confidence to do so! The pictures and video are worth it!

5.00I was a little apprehensive. But, this was a wonderful experience. They focus on safety and you having an incredible time. You are well cared for. And so many fish and turtles. The fish eat out of your hand. One of them actually wanted to eat my finger! Lots of turtles and even a stingray. The whole crew were extremely nice and well trained. Yes by all means do this!!!

5.00This was awesome! Such a friendly crew all the way around. My boys and husband enjoyed the scuba scooters. I tried it but I got nervous and the worker that was with me, was so sweet and tried to calm my nerves. Very appreciative of him for that. The boys saw several turtles and lots of fish. When they were done with the scooters, we got to snorkel.

5.00I highly recommend the Sub Scooters and SeaBobs experience with Island Water Sports Hawaii! The crew was incredibly friendly, professional, and took great care of us throughout the excursion. This was our first adventure in Hawaii, and it exceeded our expectations. The experience was unique, fun, and unforgettable. If you're looking for an amazing ocean activity while visiting Hawaii, be sure to check it out! You don't even have to know how to swim. My teenage son and I had a great time.
Would do it again.
