Catchment Properties

The Puerto Princesa Subterranean River National Park serves as a crucial catchment area for two of Palawan’s most important rivers. The Cabayugan River begins on the slopes of Mount Bloomfield, meandering through picturesque paddy fields where it naturally irrigates the farmland. Eventually, the river disappears beneath Mount St. Paul, resurfacing as the world-famous underground river, a key feature that highlights the park’s unique geological and ecological significance.

The Babuyan River, on the other hand, stretches approximately 53 kilometers, making it the longest river on the island. Both rivers are essential not only for the natural environment but also for the surrounding communities, supplying water for domestic use and agriculture, while supporting the park’s rich biodiversity and maintaining ecological balance.
