Despite being underwater, Shicheng has remained well preserved; the water actually protects it from wind, rain and sun erosion. Today, advanced divers can get up close to the ruins with dive operators such as Big Blue and Zi Ao Diving Club, which run regular dives between April and November. Since the ruins have yet to be fully mapped, the dive is still considered “Exploratory” and is limited to divers with deep water, night and buoyancy experience.
