Best Activities for Large Groups in Oahu
Submarine Scooters and Snorkeling Tours
Experience snorkeling like never before when you book this phenomenal group activity in Oahu. Your adventure begins as you board our 50-foot power catamaran and head for the clear waters of Maunalua Bay. As you ride out to your snorkeling spot, your group will enjoy excellent commentary from our captains and crew as they tell you all about the fish you’ll encounter while snorkeling, provide fun facts about the island, and point out unique landmarks.
Once you arrive at your diving location, the real fun begins! With our eco-friendly sub-scooters, you’ll experience the freedom of gliding underwater just like a majestic Hawaiian Green Sea Turtle.
Unlike traditional snorkeling, our sub-scooters allow you to breathe freely while being fully submerged. To get set up on the sub-scooter, you’ll hop in the water, where our crew will help you get safely seated and positioned. The scooter’s helmet works by creating a seal that traps air inside, similar to what happens if you lower an upside-down cup into to tub of water – air remains inside the cup.
Once you’re positioned on the scooter, you’ll be lowered 7-8 feet under the surface, always remaining tethered to the boat by a lead, and begin your self-propelled ride under the waves! Keep your eyes peeled for sea stars, octopi, blue tangs, and more!
When your 20-minute ride is done, your group will trade with the next riders. While each group is on the sub-scooter, the others can enjoy swimming or traditional snorkeling, or you can just relax on the sundeck and take in the sights.
Light refreshments and snorkeling gear are provided onboard. All you need to bring is something to swim in, a towel, reef-safe sunscreen, and sunglasses.
Requirements to Ride:
- Must be at least 10 years of age
- Must be between 4’-6’8” in height
- Must have no known medical conditions
- Weight limit of 250 pounds
- Must not be pregnant

SeaBob Super Dolphin and Snorkeling Tour

For one of the best adrenaline-filled group activities in Oahu, check out the SeaBob Super Dolphin adventure. A SeaBob is a self-propelled, eco-friendly device that lets you zip through the water at up to 12 miles per hour, letting you feel just like a super dolphin as you make banking turns and impressive jumps above the surface. Swim with the schools of tropical fish, race circles around your friends, and enjoy the high-flying thrills you can’t get from any other snorkeling adventure.
Just like the sub-scooter tour, this group activity offers the opportunity to snorkel, swim, and lounge on a beautiful catamaran while everyone takes their turn. To really commemorate the trip, consider adding a photography package and getting pictures and videos of your experience.
Refreshments and snacks are, again, provided, as well as all necessary gear.
Requirements to Ride:
- Must be at least 10 years of age
- Must have no medical conditions
- Must not be pregnant
This two-hour tour is one that will definitely be the highlight of your Hawaiian vacation.
