Unique experience!

5.00I have seen this excursion being offered for a while now. However, this is the only place I have seen it offered. Totally worth the weight! We saw so many fish and turtles, the guides knew exactly where to go. Kind of wish the scooters had gone a little faster, but it was still very enjoyable.
Great experience!

5.00Great experience! I was nervous at first but the divers stay with you the whole time. I saw so many cool fish and turtles too!
Unforgettable. Best Excursion We Did in Oahu.

5.00This Submarine Scooter Adventure was hands down the best activity we did in Oahu, and we did six different excursions during our trip. It was the very first thing my husband and I did for my birthday, and we seriously considered doing it again before we left. We only didn’t because we ran out of time. Our boat had 14 guests and 3 incredible staff. They take guests out in small groups of six, and while waiting for your turn, everyone has the opportunity to snorkel. They provide all the gear including snorkel equipment, life jackets, and flippers. The snorkeling alone was amazing. The water was crystal clear and full of fish, and it was absolutely beautiful. When the current picked up a bit, we came back on the boat, and the staff spent time talking with us, getting to know us, and giving genuine recommendations about the area and things to do. That personal touch really stood out. When it was finally our turn, I can honestly say I was not prepared for how incredible the experience would be. There were so many fish swimming right up to us, and we saw at least three sea turtles in our immediate area. I will never forget it. You are never alone during the ride. There is a free diver with you the entire time, along with someone taking photos and videos. They do offer those for purchase afterward, and we absolutely bought them because this is truly a once-in-a-lifetime experience. They had snacks available, a large bin of chips and water, which was perfect. I sometimes get seasick and did not want heavy food anyway. As someone who does get seasick, I can confidently say I had zero symptoms and would 10 out of 10 recommend this experience. I truly cannot speak highly enough about the crew and the entire experience. I wish I had brought cash to tip, but they also accept Venmo, which was convenient. They also have a dry box on the boat to keep your belongings safe and dry. If you are on the fence, book this. It's worth every penny and easily the most memorable thing we did.

5.00First the staff here is absolutely amazing. They are very helpful. In doing this adventure, they were very clear with directions, communication methods under water, provided snacks if you wanted them, had dry storage, and even pointed out sea life to me when I wasn't looking in the right direction. I would, without hesitation, do this again, hopefully in warmer waters!

Incredible Underwater Adventure with Attentive Guides

5.00We had a fantastic time scootering around the reef! The experience was incredible—we were surrounded by schools of fish the entire time we were underwater, and we even spotted a sea turtle. Having a fish-feeding net attached to the front of the scooter made the interaction even better. The guides were excellent and very attentive. They provided thorough instructions before we boarded and gave us a final review right before we descended, which made us feel completely safe and comfortable breathing underwater. Since our tour only had five people, the experience felt very personal and individualized. The boat ride to and from the dive spot was lovely, and they provided snacks and water. Just a heads-up for future travelers: there is no bathroom on board the boat. Overall, a safe, fun, and memorable adventure with great photo options available!

5.00I was terrified as a non-swimmer, but this is great for people like me who are non-swimmers. The guides were really great and EXTREMELY helpful in making sure everyone was comfortable and got the most out of their time on the scooters.
