Like swimming in an aquarium
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.

Best experience ever!
It was an amazing experience, cole and staff did a great job. We were able to see 🐢 and snorkel until it was our turn to go on the submarine scooter.

Surprised with customer service
I should have cancelled our excursion due to the tropical storm. I contacted the company several times only to receive a message that the storm will have passed by then. We were poorly greeted at the shop and felt like they were just doing their job. Our daughter and several passengers became sea sick and unable to enjoy or do the dive. They had a third boat and felt they could have offered to take people back. Overall, the customer service was poor and they should have been honest about the conditions and given people the opportunity to cancel.

The crew and captains...
The crew and captains were professional and fun the experience was unique and memorable would recommend.

Underwater Adventure!!!
This was honestly one of the coolest experiences I’ve had. It’s not for everyone, though, if you are at all claustrophobic…please avoid it… This is a great option for snorkeling if you have glasses like me….the staff is with you the whole time making sure your adventure is maximized…we saw hundreds(maybe thousands) of fish, and even a few sea turtles. The only negative is I wish we could do it longer

Why this scores 71
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Oahu: Submarine Scooter Adventure: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Oahu.
How much does Oahu: Submarine Scooter Adventure cost?
+
Prices start at $188 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Oahu usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Oahu: Submarine Scooter Adventure take?
+
Plan for about 2 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Oahu is not rushed.
Is Oahu: Submarine Scooter Adventure worth it?
+
It holds an Outty Ranking of 71 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.8/5 across 2,405 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable most popular in Oahu, and how flexible the cancellation terms are.
Can I cancel or reschedule Oahu: Submarine Scooter Adventure?
+
No. This experience is sold on a non-refundable basis, so only book a date you are confident about. Similar experiences in the city do offer free cancellation if flexibility matters more than price.
Is Oahu: Submarine Scooter Adventure suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 2-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Oahu: Submarine Scooter Adventure?
+
Around 842 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Oahu can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Oahu and add a light layer if any part of the 2-hour experience runs outdoors or after sunset.
Where does Oahu: Submarine Scooter Adventure start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Oahu within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Oahu?
+
On Outty we rank every Oahu experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Oahu: Full or Half Day Grand Circle Island Tour, Oahu Small-Group Circle Island Tour with Turtle Snorkeling, Pearl Harbor Remembered Tour. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Oahu?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Oahu?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
