Breathing Observation Bubbles (BOB) Underwater Adventure
This is one of the newest ocean activities available on Oahu. Explore the island’s underwater world with a submersible scooter, also known as a Breathing Observation Bubble (BOB). These self-propelled, eco-friendly underwater scooters are easy to operate and no scuba diving experience is necessary.
The scooter allows you to sit on a seat with your head inside a clear acrylic bubble, which is filled with air from the storage tank. You can cruise around just below the water’s surface and see a variety of tropical marine life up close. A master diver will accompany you on your BOB Underwater Adventure.
This is surely one of the most unique activities that books up quickly, so make your reservation early. Below are two great Oahu underwater scooter tours to choose from:
