The Site features a spectacular limestone or karst mountain landscape with one of the most impressive cave systems in the world. It contains an 8.2 km long underground river that flows directly to the sea. The lower half of the river is brackish and subject to the oceans tide. A subterranean river flowing directly into the sea and the associated tidal influence makes it the most unique natural phenomenon of its type to exist. The discovery of 11 minerals, scientifically and aesthetically unique speleothems, and a 20 million year old Serenia fossil justifies the declaration of the Puerto Princesa Underground River as one of the New 7 Wonders of Nature.
The Site also contains a full mountain to sea ecosystems and protects forests that are important for biodiversity conservation. It is a representative of Palawan Moist Forests, which are among the most significant in Asia, and is noted for high levels of regional and local endemism. The Site serves as habitat to numerous endangered, rare and endemic wildlife species. In the coastal area, mangroves, sea grass beds and coral reefs are found.
In recognition of its outstanding universal value, it was inscribed to the United Nations Education, Scientific and Cultural Organization’s World Heritage List on December 4, 1999. Inscription to this prestigious list confirms the outstanding universal value of the Park and its well-integrated state of conservation.
