The PPSRNP lies approximately 360 miles south of Manila. It is located in the midwest coast of Palawan, some 76 km northwest of Puerto Princesa City. The present boundary covers the entire catchment of the Underground River. The adjoining Barangay Marufinas also has important values, particularly for forest conservation. This is thus important in protecting World Heritage values of the Site. Its geographic coordinates are 10′ 10 north, 118′ 55 south.
