Puerto Princesa, Palawan
Subterranean River
To promote environmental conservation, the management limits the number of tourists entering the Puerto Princesa Underground River each day. This effort helps minimize disturbances to the species living in the area and ensures that future generations can continue to appreciate the national park. Only tourists with a permit can take the Puerto Princesa Subterranean River Tour. The permit usually takes about three days to process, and travel agencies can arrange it in advance to guarantee a slot on the day of your tour.
