Natural wonders - Puerto Princesa Underground River

Natural wonders - Puerto Princesa Underground River

The Puerto Princesa Subterranean River National Park (PPSRNP) is one of the most important protected areas of the Philippines. It features a spectacular limestone or karst landscape withone of the most complex cave systems. It contains an 8.2 km long underground river that flow directly to the sea. The lower half of the river is brackish and is affected by the ocean’s tide. An underground river directly flowing into the sea, and the associated tidal influence, makes it a significant natural phenomenon. The discovery of at least 11 minerals, crystal and egg shape rock formations, and a 20 million year old Miocene age serenia fossil in the cave further add to its scientific value. The Puerto Princesa Underground River is declared as one of the New 7 Wonders of Nature.
