Sea Walker - Đi bộ đáy biển
Sea Walker – Underwater Walking puts you on the seabed of Hòn Mây Rút Ngoài, a small island in Phú Quốc's An Thới archipelago, inside Namaste's coral park. Instead of snorkelling, you wear a transparent, astronaut-style helmet that supplies air from the surface, then simply walk across the sandy floor at a calm depth of around five metres and look straight out at gardens of living coral and the fish that swarm through them.
It is one of the few places in Vietnam where the underwater world is presented as a managed, cultivated 'garden' rather than a wild reef, so the experience is gentle, guided and open to almost everyone — you do not need to swim, dive or be a confident snorkeller, which makes it a standout activity for families and first-time ocean explorers.
