Puerto Princesa Subterranean River National Park

Puerto Princesa Subterranean River National Park is a cave network in northwestern Palawan housing an underground river that flows through limestone formations. The navigable section spans several kilometers and takes visitors through caverns with multiple levels and natural geological features.

Archaeological evidence within the caves indicates human settlements dating back thousands of years in this region of Palawan. These discoveries suggest that people long ago used the cave system as shelter and a source of resources.

Local communities view the park as a representation of environmental stewardship, with residents working together to maintain sustainable tourism practices and protect the landscape. People here see the river system as central to their connection with nature and regional identity.

Visitors should arrange permits in advance and multiple transport options are available from the city center. Weather conditions can change rapidly, so it is wise to bring appropriate clothing and consult with local guides about the best time to visit.

The cave system features a second level with internal waterfalls and a section inhabited by large bat colonies. These lesser-explored inner structures offer visitors unexpected natural phenomena that often go unnoticed.
