Brief History

Puerto-Princesa Subterranean River National Park encompasses one of the world’s most impressive cave systems, featuring spectacular limestone karst landscapes, pristine natural beauty, and intact old-growth forests and distinctive wildlife. It is located in the south-western part of the Philippine Archipelago on the mid western coast of Palawan, approximately 76 km northwest of Puerto Princesa and 360 km southwest of Manila.

The property, comprising an area of approximately 5,753ha, contains an 8.2km long underground river. The highlight of this subterranean river system is that it flows directly into the sea, with its brackish lower half subjected to tidal influence, distinguishing it as a significant natural global phenomenon. The river’s cavern presents remarkable, eye catching rock formations. The property contains a full mountain-to-sea ecosystem which provides significant habitat for biodiversity conservation and protects the most intact and noteworthy forests within the Palawan biogeographic province. Holding the distinction of being the first national park devolved and successfully managed by a local government unit, the park’s effective management system is a symbol of commitment by the Filipino people to the protection and conservation of their natural heritage.

The Puerto-Princesa Subterranean River National Park features a spectacular limestone or karst landscape. It contains an underground river that flows directly to the sea. The lower half of the river is brackish and subject to ocean tide. The associated tidal influence on the river makes this a significant natural phenomenon. The river’s cavern exhibits dramatic speleothems and several large chambers of as much as 120m wide and 60m high. Its accessibility and navigability up to 4.5km inland allows it to be experienced by the general public, who can view the magnificent rock formations on a river cruise unequalled by any other similar experience elsewhere in the world.
