Undersea walk experience
Undersea walk in Grand Baie lets non-divers walk on the seabed wearing a clear, air-filled helmet while breathing normally. Guided by trained instructors, participants stroll at shallow depths (typically 4–6 m) among coral bommies and tropical fish for a close-up marine experience without needing scuba certification or strong swimming skills.
