UNDERGROUND
RIVER
Introduction
Puerto Princesa’s pride is easily the Puerto Princesa Subterranean River (or Underground River), a UNESCO World Heritage Site and one of the New 7 Wonders of Nature.
The 8.2-kilometer river, said to be the longest navigable underground river in the world, winds its way underneath a mountain range, through the St. Paul Underground River Cave, and then goes out into the South China Sea. The journey through the cave system alone is 24 kilometers long.

These mountains have been formed from a dark grey limestone, which has formed in the Late Oligocene - Early Miocene - some 16 - 20 million years ago. The highest summit is the 1,027 m tall Mount Saint Paul.
