Puerto-Princesa Subterranean River National Park
This park features a spectacular limestone karst
landscape with an underground river. One of the river's distinguishing
features is that it emerges directly into the sea, and its lower portion
is subject to tidal influences. The area also represents a significant
habitat for biodiversity conservation. The site contains a full
'mountain-to-sea' ecosystem and has some of the most important forests
in Asia.
