Traveled with my wife and kids, 16 and 13. They all loved this activity! You dont need to know how to swim, and the guys were all very patient and extremely talented. My wife was very nervous and scared, but they were patient and helped her get into the scooter. They had alot of divers in the water to help and make sure everyone is safe. You only around in the water. It may seem short, but its actually the perfect amount of time.
If you tend to get seasick, make sure to drink some draminine before. Next time I'm in Honolulu, I'll definitely do this again.

This 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.

I felt safe enjoyed myself went down 10 feet had a great group that we went with. The guys were very professional. Amazing how they get swimming in that water. I’m handicap and they helped me when I got in and out of water. Left my walker in the office building.
Kirk_S, Jun 2026
We loved it. The fish, the turtles, the swimming, jumping off the side of the boat into the ocean, and then the subs. AWESOME

Great experience all around. Guides were kind, helpful, and lots of fun. I am not a strong swimmer and was somewhat nervous, but they were thorough in their instructions and put me very much at ease. I would recommend this experience hands down.
Samantha_T, Jun 2026
What a fun experience! My daughter (14) and I had a wonderful time on this excursion. The staff is very well trained and friendly! We saw several sea turtles from the catamaran. My personal scooter guide helped me find one while I was in the scooter as well! It was an amazing experience watching all the sea life while scooting around the ocean! We also enjoyed snorkeling prior to our turn in the scooter. 10/10 would recommend!
Clara_W, Jun 2026
It was a wonderful experience. I can’t swim and the captain and his staff were super helpful, and did everything to keep us safe and make us feel safe! It’s a once in a lifetime experience that I highly recommend!
Lisa_G, Jun 2026

Such an amazing trip. It was my sons #1 activity we did over a two week vacation, and we had a lot planned. Staff was amazing, experience was amazing. Dont double think it, book immediately!
Jason_Y, Jun 2026
I gifted this activity to my wife, my mother-in-law, and two of their friends. I was embarrassed to learn they were only on the submarine scooters for 20 minutes, especially since I had told them it was a 2-hour experience based on the listing. I later realized the actual scooter ride is only 20 minutes, and the remaining time is spent snorkeling. The itinerary is misleading and needs to clearly reflect this time breakdown.
Response from Host, Jun 2026
Thank you for your feedback. We're sorry to hear that the experience did not meet your expectations.
We would like to clarify that the 20-minute underwater scooter ride is clearly stated in the tour description on Viator. The description explains that guests enjoy a 20-minute underwater adventure followed by time to swim, snorkel, relax on the boat's shaded deck, and enjoy complimentary snacks and beverages while learning about the island's natural and cultural history from the crew.
The total experience lasts approximately two hours, with the underwater scooter portion representing one part of the overall tour. We understand how important it is for guests to know exactly what to expect, which is why the activity breakdown is included in the listing prior to booking.
We appreciate your comments and will continue to look for ways to ensure the tour details are as clear as possible for future guests.

The submarine scooter ride was a novel experience, but it lasted about 30 minutes instead of 2 hours. You don't have full control, only the ability to turn around. It is controlled by the safety instructors.

The team really allows you to enjoy the best experience ever. They direct and literally stear you to where the wildlife is located.
Karen_B, May 2026
A must do experience if you never done it. The staff were excellent, friendly and helpful. One on one assistance was very comforting. As a non swimmer, they made it easy and enjoyable. While waiting your turn for the submarine scooter, you can snorkel. A wonderful experience. We would do it again!
Chelsea_W, May 2026
I absolutely love this experience. Even if you can't swim, you can still go on this excursion because it is so easy and fun. The instructors really help you out, especially if you don't know how to swim. I would absolutely do this! Once in a lifetime experience.
Amy_P, May 2026
The crew for the scuba scooter were great! This was by far my favorite experience in Hawaii!! The guys were so patient and accommodating. I’m not a great swimmer and I had a broken elbow but they helped me have the most amazing adventure. The photos and video they took were worth every penny too. They helped me navigate the scooter. Helped us see fish and turtles. We weren’t rushed at all. Five stars and more!!
Daniel_R, May 2026
Due to size of the group, it took longer than expected, but it was still a valuable excursion to book. I would do it again if the opportunity were to arise in the future.
Michelle_D, May 2026
We are so happy we took this opportunity to have such a unique experience. The captain and crew are amazing and patient. The photos taken during the dive are crystal clear and capture the moments. Hopefully everyone enjoys similar vibes, Mahalo.

Absolutely amazing experience! The staff were amazing and we were blown away by the view and how close we could get to the sea life! We would do it again in a heartbeat!
Jason_Y, May 2026
Great experience and well worth it. Great staff and saw sea turtles, dolphins, and even petted the fishes
Gabriel_Z, May 2026
The guides are awesome! My wife was so afraid of the ocean and going in they were patient, funny and were attentive to her above water and below.
Linda_B, May 2026
Excellent service by the entire crew. There were several of us who were abit nervous about diving down in the water. Everyone had an experienced diver throughout the entire activity to ensure our safety and guide us down to see 👀 the sealife below. You could go snorkeling while you waited for your parties turn to go down. The crew members were all professional, kind and friendly people. Highly recommend. Special thanks to Finn, Boom and Uncle for making this an awesome experience.
