Enchanted River (Hinatuan)
A popular spring-fed swimming spot in Mindanao whose pool hides an underwater cave entrance at about 30 m. Tidal flow and a halocline change cave conditions sharply; no dive access procedure is published.
The spring pool at the head of the Enchanted River is a busy public attraction managed by the Hinatuan municipality as an eco-tourism area. The cave entrance lies about 30 m down in the pool.
Filipino Cave Divers reports describe seawater entering on high tides, a halocline around 33 m, and a cave that cannot be entered near its peak outflow. The same reports note a partial ceiling collapse found in 2013 and concern that heavy visitor numbers may harm a fragile ecosystem.
De omgeving
Spring pool over an underwater cave; brackish to salt water can intrude with the tide, with a halocline recorded at 33 m.
Omstandigheden
Conditions depend on the tide: FCD divers recorded inward current, seawater and very poor visibility above the halocline at high tide, and still, very clear water at another tide state.
