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 an awesome experience of our family of four! The divers were extremely attentive and made us feel at ease. If there is any anxiety that is deciding factor on going or not, GO!! It was the best experience on the island so far!!

The snorkeling place location was nice, but there were two disappointments:
1. We thought we could drive scooters by ourselves, but turn out we were just sitting there and driven by scuba divers.
2. At the end of the trip, we paid hundred dollar for videos and photos, but never got them.
Response from Host, Jul 2026
We are sorry our tour did not meet your expectations. Please keep in mind that this tour is in open ocean which can have strong currents. If you felt you were driven by our safety divers, it is most likely due to a strong current during your tour, or that you were driving the wrong direction. Our divers are there for your safety, and will take control of your scooter if they need to. Please contact us to check your email address for your pictures.

This was one of my favorite experiences!!! The Captains and crew were professional, informative and attentive. Boone was creative with the videos and pictures. I highly recommend this adventure.
poncho_B, Jul 2026
It was so fun! The guys were so patient with us. My niece was scared and they helped her to enjoy the extra
Yves_G, Jul 2026
It's scary at first, especially if you don't know how to swim, but the divers are helpful. Take a sea sick pill if you're sensitive to motion.
Rohan_P, Jul 2026
Anyone curious to know whats down there in pacific ocean,but dont have any swimming or scuba experience,then this is your best possible option.

If you’re thinking about booking the Submarine Scuba Adventure (Scuba Scooter) with Island Water Sports Hawaii (also known as Bob’s Hawaii Adventure), do it—you won’t regret it!
I booked this excursion for my husband’s birthday, and it ended up being one of the highlights of our trip to Oahu.
I’ll admit, I was absolutely terrified. I’m claustrophobic, and the thought of being underwater had my anxiety through the roof. The entire team was beyond patient, kind, and encouraging. They never rushed me, explained everything thoroughly, and made me feel completely safe every step of the way. I had a diver with me one-on-one the entire time underwater, and that made all the difference. Thanks to their incredible support, I was able to overcome a fear I never thought I’d conquer.
The experience itself was unforgettable, and the crew made it even more special. They captured amazing photos and videos of our adventure, and the pricing was very reasonable—something we’re so grateful to have as a lasting memory.
From start to finish, the staff was professional, caring, and genuinely wanted everyone to have an amazing experience. If you’re visiting Oahu, I cannot recommend this adventure enough. Whether you’re an experienced diver or someone like me who’s nervous about the water, you’re in the best hands.
Thank you for helping me create such an unforgettable birthday for my husband—and for helping me accomplish something I never thought I could do!

AMAZING!!! Team is well organized and prepared!! Get way more than you pay for!! Seeing the fish and sea turtles so close. Bonus was pics and video available for purchase after!! Will do any opportunity we can!
Lisa_G, Jul 2026
It was fun. Very windy so the water was choppy. We saw fish and a couple sea turtles. It was a very cool experience.
Ross_C, Jul 2026
Was a great experience saw turtles and my family had a great time. Staff was great and guided us on the scooters. The photo option was great.
John_O, Jul 2026
Crew was friendly and accommodating. My daughter and I had a great time! Being able to snorkel while waiting for our turn was a nice use of time and let us enjoy the down time. Would definitely recommend!
Yinia_Y, Jul 2026
Did 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!
Rick_N, Jul 2026
I 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!!!
Terrence_S, Jul 2026
Unique and one of a kind experience. Would recommend for all. No swim experience needed. Staff was great.
Stephanie_T, Jun 2026
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.
Christine_F, Jun 2026
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
Anonymous, Jun 2026
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
Great personalized experience! Almost a personal tour. We went out when other tours were being cancelled due to weather and a great time

Ann_C, 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!
