If you’ve ever wondered what it might be like to glide beneath the waves without the fuss of scuba gear or the claustrophobia of a traditional submarine, the Oahu Submarine Scooter Adventure offers a unique blend of ease, excitement, and eye-opening marine encounters.
This tour promises a two-hour journey that combines a scenic boat cruise with the thrill of riding your own electric underwater scooter, making it ideal for travelers seeking a safe yet exhilarating way to explore Oahu’s vibrant marine life.
What we really appreciate about this experience is how it caters to a broad range of visitors. First, no previous swimming or diving experience is necessary—the guides are there to ensure you’re comfortable every step of the way. Second, the boat cruise itself offers stunning views of Diamond Head and Maunalua Bay, adding a scenic layer to your underwater adventure.

If you’re looking for an activity that combines adventure, comfort, and spectacular scenery, this tour is a solid choice. It’s especially perfect if you want to see turtles, tropical fish, and coral in a controlled, guided setting.

The Itinerary: What to Expect

Starting at Bob’s Hawaii Adventure on Keahole Street, the journey begins with a friendly check-in. You’ll meet your guide and fellow adventurers, then climb aboard a 50-foot catamaran. The boat ride itself is a highlight—cruise past Koko Crater, Maunalua Bay, Diamond Head, and the Koolau mountains, all offering photo-worthy scenery. The ride is described as “rocking and rolling” at times, which is part of the fun, but worth noting if you’re sensitive to motion.
Once you arrive at the designated dive site, the crew will give a comprehensive safety briefing and show you how to operate your electric underwater scooter. This device is a marvel—self-propelled, eco-friendly, and intuitive to use. Reviewers mention that the operation is straightforward, even for beginners (“clear instructions,” as one reviewer put it), and the guide will be right there beside you, helping you feel comfortable.
The underwater segment lasts around 20 minutes, during which you’ll be led through schools of tropical fish, colorful coral, and, if luck is on your side, green sea turtles. One reviewer described it as “being near a turtle eating,” which captures how close and intimate this encounter can be. To attract fish, the guides sometimes attach small bags of fish food, resulting in the fun experience of petting and feeding the tiny swimmers.
After your scooter time, you’ll have the option to snorkel further using provided gear or relax on the boat’s deck. The crew offers snacks and drinks, making for a relaxed, social atmosphere. The boat then returns to the starting point, wrapping up your aquatic adventure.

The equipment provided includes wetsuit tops, snorkel gear, and fins. The wetsuit tops are especially appreciated, as they help keep you warm and comfortable in the water. The electric scooter is designed to be user-friendly, with most reviewers mentioning how easy it was to learn and operate.
While some guests have noted that the scooters aren’t as exciting as traditional diving gear, most agree that the ability to zip around underwater and see fish at close quarters makes up for it. The helmet design allows plenty of space to look out and scratch your nose if needed, reducing feelings of claustrophobia, which some first-timers worry about.
Viewing Marine Life: What to Expect
The marine life sightings are one of the tour’s big draws. Guests frequently mention seeing green sea turtles, schools of tropical fish, and vibrant coral reefs. As one reviewer put it, “you might see an octopus or ray,” though of course, wildlife sightings depend on the day’s conditions and luck.
To maximize your chances, arrive prepared to snorkel as well. You’re given snorkel gear, so you can float around or explore more freely after your scooter ride. Many guests find swimming next to sea turtles and gently feeding fish to be one of the most memorable moments of their trip.
Guides, Group Size, and Overall Atmosphere
The crew’s professionalism and friendliness earn high praise across reviews. Many mention guides like Ogee and others as encouraging, knowledgeable, and supportive, especially for those feeling nervous. Several reviewers note how they felt genuinely cared for, which boosts confidence in this activity.
With a maximum group size of 30 travelers, the tour maintains an intimate, friendly vibe. This smaller group setting allows guides to give more personalized attention and ensures everyone feels safe and included.
Price and Value
At $188.49 per person, this experience falls into a mid-range price bracket for Hawaii adventures.
