Why Our Insiders Chose This Tour

What You Can Expect

Oahu Submarine Scooter Adventure

Get Up Close to Green Sea Turtles

Make your way to Honolulu's Keahole Street to meet your group and friendly, experienced tour guide. 

Climb aboard a 50-foot (12-meter) catamaran and cruise up the coast of Oahu past great views of Koko Crater, Maunalua Bay, Diamond Head and the Koolau mountain range. 

When you reach the dive location, listen to a safety briefing and instructions on how to operate your underwater scooter. This self-propelled, electric scooter is an environmentally-friendly way to explore Oahu's extensive underwater world. Submerge on your scooter and follow your guide through schools of tropical fish, past living coral reefs and green sea turtles. 

After your turn on the scooter, don fins, a mask and snorkel to explore the water more fully or just relax on the boat's deck. Indulge in some snacks and drinks on board and listen to your guide talk about the history of the area, including pointing out filming locations from several popular television shows and movies. 

At the conclusion of your 2-hour tour, the catamaran will return to your departure point.

Put this one on your bucket list for Oahu! I can swim and snorkel but wouldnt be up to scuba diving so when I found this on Viator for Oahu it ticked all the boxes. Most amazing experience, only short ride out to the scooters and the excellent staff guided us on safety and how to work scooters. You are told how to enter the bubble, a short dunk under water and they position the bubble over your head, you resurface and are inside the bubble, you are breathing air and sitting on a scooter. Each person gets approx 15 mins on scooters with the crew with you at all times pulling you down 30 feet to sandy bottom where you see green turtles and beautiful coloured fish. They come right up to you as there is a basket of bread in your hand to entice them. Photos and a short video are taken of your experience. It costs extra but absolutely worth it as I relive this most amazing experience regularly. When not on the scooters you can snorkel around the boat and this was just as amazing as a turtle decided to swim through the snorkellers! All snorkeling gear is provided and you must use fins as the currents around the boat are pretty strong. Crew wonderful, boat clean, with plenty of fresh snacks and soft drinks. The restrooms in the office are just alright but just do it.

It was amazing!! It was beyond professionally organized and so much fun! Let me start off by saying that I can’t swim - and it didn’t hinder me from doing this. They have one professional diver per person. It was the most awesome thing I’ve done on any vacation. I highly recommend it!! Do it!
