As an experienced snorkeler, I prefer regular snorkeling, as you have more control, but I would highly recommend this for non-swimmers. The submarine scooter goes anbout 10 ft down annd goes very slowly while tethered to the boat. Even for experienced snorkelers, you still get time to just snorkel. The crew were fantastic! There were lots of fish and several green sea turtles getting groomed by the fish. I had a great time!

Amazing ! If you love the water and want to see beautiful ocean life, then this is the tour for you! So happy we decided to this they were very helpful took amazing pictures and videos of the experience and made us feel so safe ! 100% need to do again
Staff was incredibly friendly and patient with explaining how everything works. The actual experience itself was amazing!
This was our second time doing this. We brought 4 teenage boys and they had an absolute blast!!
The crew was very good with our 4 year old who was just watching.
Absolutely brilliant don’t let age stop you I’m 60 and did it easily the divers with me were so friendly and helpful felt totally safe and cared for.
The divers were very patient and caring. The ship owner was also a great conversationalist and motivator. The whole crew were amazing.
Sub scooter adventure was such a blast! I can't even swim and the crew made me feel totally safe the whole time, super patient and reassuring. Boone especially went above and beyond, so kind and attentive to little things without making a big deal out of anything. Made me feel comfortable enough to actually enjoy myself instead of stressing. Highly recommend if you're nervous in water like me!
Don’t wait to go last just do it! It was amazing! Only complaint is that we paid for pics on the boat and still don’t have them :( we didn’t take our own pics & could’ve
This is a 6 star experience! I have a dozen scuba dives, and this was more fun than any of them. The dive masters are very attentive, the crew knowledgeable and friendly. No skills required except a smile on your face and a sense of adventure.
The crew and captains were professional and fun the experience was unique and memorable would recommend.
The tour was great and everyone there was so friendly & helpful
As a non swimmer, they made me feel comfortable & enjoy my time under water
Awesome,they have a diver with you at all times ,it was very cool bucket list item. Would definitely recommend this to family and friends
We had an incredible time on the submarine scooter tour! It was such a unique experience and definitely one of the highlights of our trip. The underwater views were nice and we were able to feed the fish from our scooters. The instructors made us feel safe and comfortable every step of the way. One of the best parts was finding out that some of the instructors were from the Midwest, just like us (Indiana/ Chicago). We had a great time chatting and sharing some hometown pride. Go Bears (Da Indiana Bears)....lol 🐻 The entire staff was friendly, knowledgeable, and made the experience so much fun. We highly recommend this tour to anyone visiting Hawaii. You won't be disappointed! One tip I'd absolutely recommend is taking Dramamine (or another motion sickness medication).
Great activity to do if you are ok getting deep in the ocean. We were 1 mile away from the shore and 10ft below the water sometimes.
I saw turtles swimming by me, fishes eating out of my hands, and a lot of other marine animals. I Loved it. It made my last day in Hawaii so much fun!
I highly recommend it.
No swimming experience needed, but you do have to duck you head underwater. It is loud, but SO worth it! Saw hundreds of fish and lots of sea turtles.
Staff was very friendly and knew what they were doing, one of the best excursions on the island being able to see the fish swim right up to you and eat out of your hands was great plus a sea turtle swam right past me
Very friendly staff, easy to work with during a rough storm with us. Very safe and I felt secure with the staff down under water with us. Highly recommend to do this great fun experience.
These guys were top notch! Docks, boat and equipment were clean. Staff was knowledgeable, friendly, encouraging, patient, respectful, and fun! They answered every question and gave clear instructions. We felt safe throughout the entire experience. They made sure we saw as much as utterly possible. Then there’s the video and the pictures! They captured every aspect we would have if we were filming ourselves!
It was very well organized. I felt very safe and enjoyed every minute of it. Staff was very pleasant. I would definitely recommend this.
If you don’t know how to swim, no worries! They are awesome in making you feel safe and are with you the entire time. A MUST experience you should try with your family. Fish eating out of your hand. So cool
The underwater scooters were cool and the photos reasonably priced. Had about 20/25 minutes in the water which was long enough, saw fish and turtles. Had to put head under water to get into the scooter which was the hardest part. Only downside was the boat was quite rocky so if you get seasick can make it difficult but if you don’t it’s a fun experience.
Experience was awesome , and crew was friendly experienced and made sure followed all safety procedures to make it beautiful experience. My kids loved it.
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.
It was so fun! The guys were so patient with us. My niece was scared and they helped her to enjoy the extra
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.
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!
It was fun. Very windy so the water was choppy. We saw fish and a couple sea turtles. It was a very cool experience.
