Oahu Submarine Scooter Adventure: An Underwater Experience Like No Other

Imagine zipping through the waters off Oahu on your own electric underwater scooter, floating past coral reefs, schools of tropical fish, and friendly green sea turtles. For about two hours, you’ll be surrounded by some of the most beautiful marine scenery Hawaii has to offer, all while enjoying the comfort and safety of a guided tour. Starting at around $188 per person, this tour is popular enough to be booked about 28 days in advance, and it’s a fantastic way to add a splash of adventure to your Hawaiian holiday.
What makes this experience stand out? First, the chance to ride your own self-propelled scooter beneath the surface—something quite different from a typical snorkel trip. Second, the boat cruise along the coast provides stunning views of Diamond Head, Koko Crater, and the lush Koolau mountains—a scenic journey not to be missed. We also appreciate that no previous experience is needed, making it accessible for beginners and thrill-seekers alike.
However, it’s worth noting that this activity isn’t suitable for everyone—motion sickness can be an issue, especially on the rocky boat ride, and participants should be prepared. It’s best suited for those who are comfortable with water and are eager for a guided, safe adventure. If you love marine life and unique ways to explore underwater scenery, this tour might just be your favorite Oahu activity.

The Itinerary Breakdown
Your adventure begins on Keahole Street in Honolulu, where friendly guides welcome you and explain what to expect. The tour is operated by Island Water Sports Hawaii, and features a 50-foot catamaran cruise along the coast. This cruise, lasting approximately 30 minutes, offers spectacular views of iconic landmarks, including Koko Crater, Diamond Head, and the Koolau mountains, all framing this scenic journey. It’s a moment to relax and soak in the Hawaiian landscape from the water, setting the mood for your underwater outing.
Once you reach the dive site, the crew conducts a safety briefing and demonstrates how to operate the electric underwater scooter. This is where the real fun begins. The scooters are designed to be easy for novices—self-propelled, environmentally friendly, and powered by electric batteries—allowing you to glide effortlessly through the water.
Underwater Exploration: What You Can Expect
The underwater portion lasts about 20 minutes, during which you’ll follow your guide and explore coral formations, schools of tropical fish, and the chance to swim alongside green sea turtles. Many reviews highlight how close and personal this experience feels: “Fish hang out near your helmet, and you can pet them with a shake of fish food,” one reviewer noted. The helmets are spacious enough to avoid feeling claustrophobic, with side windows to look out or scratch your nose if needed.
Some travelers, like Cindy, shared that despite their initial discomfort due to claustrophobia, the crew’s support helped them get through it. Others, like William, rave about the professionalism and friendliness of the crew, making it an experience both safe and fun, even for those who don’t swim well. The presence of snacks and drinks on board adds to the relaxed vibe—it’s as much about enjoying the scenery as it is about the underwater adventure.
Additional Activities Post-Scooter
After your scooter experience, many choose to continue snorkeling with the provided gear or simply lounge on the boat deck, enjoying the warm Hawaiian sun. The crew’s commentary on the area’s history and marine life enriches the experience, making it both educational and entertaining.
The Overall Experience: What Travelers Say
Reviewers consistently praise the knowledgeable guides and the supportive atmosphere, noting that even those who are nervous or first-time snorkelers felt comfortable. Many mention how the crew’s encouragement helped them push past their fears and truly enjoy the underwater scenery.
While most rave about the abundant marine life, some mention that they wished the trip lasted longer or that they saw more variety of sea creatures. The value for money is generally considered excellent, given the comprehensive equipment, guides, snacks, and the boat cruise.
A couple of reviews highlight the importance of motion sickness preparation, as the boat ride can be rocky—something to keep in mind if you’re prone to seasickness. Participants with medical conditions or claustrophobia should also consider their comfort level with enclosed helmets underwater.
