The Puerto Princesa Subterranean River National Park is one of the most important protected areas of the Philippines. It’s a complex system of limestone caves, under which flows an underground river 8.2 kilometers long, that goes directly into the sea. The lower part of the river is brackish and is affected by the tide.
The discovery of 11 minerals, crystal and egg shpaed rock formations, and a sirenia fossil from the Miocene, dated 20 million years, helped to raise the scientific value of this place.
The Puerto Princesa Underground River has been declared one of the 7 new wonders of nature.
