It includes major formations of stalactites and stalagmites, and several large chambers. The lower portion of the river is subject to tidal influences. The underground river is reputed to be the world's longest.
The area also represents a significant habitat for biodiversity conservation. The site contains a full mountain-to-the-sea ecosystem and has some of the most important forests in Asia.
