Walking on the Reef: Seawalker Underwater Helmet Experience at Green Island
Seawalker is one of Green Island’s most distinctive and inclusive activities, an underwater helmet walk that allows participants to walk along the seafloor of the reef at a depth of approximately four metres, without any swimming ability, scuba certification, or prior underwater experience required. A weighted helmet sits on your shoulders and receives a continuous supply of air from above the surface, allowing you to breathe normally and speak while completely submerged. The fish come remarkably close. The reef floor is right beneath your feet.
How It Works
Participants descend a ladder from a pontoon into the water, with guides assisting at each stage. The helmet, which covers the head and shoulders and is continuously supplied with air — allows participants to breathe naturally underwater without any swimming or air management required. The weighted helmet keeps participants at the seafloor, where reef fish swim close by. Allow about 60 minutes from the safety briefing to finish, including time spent walking and simply observing the reef community at close range.
Who Can Participate
Seawalker is designed to be accessible to almost all visitors. Swimming ability is not required, participants are supported throughout. Children aged 12 and over can take part with parental consent. Participants with some medical conditions may not be eligible; a standard health questionnaire is completed before the activity. The experience is particularly popular with older guests, children, and anyone who has always wanted to experience the reef underwater but found the idea of snorkelling or diving daunting.
What to Expect
The reef at Green Island is typically alive with fish that have become accustomed to Seawalker participants and approach closely to be fed. The experience of having reef fish, wrasse, parrotfish, surgeonfish, taking food from your hand while standing on the seafloor is remarkable and unexpected in its intimacy. The clarity of the water and the immediate proximity of the coral are both striking from the Seawalker perspective.
Booking
Seawalker sessions at Green Island can be booked as part of a tour package or added on arrival at the island activity desk. Session times are scheduled throughout the day; booking in advance is recommended during peak season. Participants should advise of any medical conditions at the time of booking.
