For those seeking an accessible and thrilling experience beneath the waves, underwater scooter adventures offer a unique opportunity. These self-propelled scooters allow even non-swimmers to glide effortlessly through the ocean, observing tropical fish, coral reefs, and sea turtles up close.
What Is an Underwater Scooter Adventure?

An underwater scooter, also known as a Breathing Observation Bubble (BOB), is a self-propelled electric vehicle equipped with a helmet-like breathing apparatus. Riders sit comfortably while their heads remain dry inside the bubble, breathing normally as they explore the underwater world. No prior snorkeling or diving experience is required, making it ideal for beginners and families.
