Subterranean River Philippines
With the goal of environmental conservation, the management strictly limits the number of tourists entering the Puerto Princesa Underground River each day. This regulation helps protect local wildlife and ensures this national park remains accessible for future generations. Visitors must secure a permit to join the Puerto Princesa Subterranean River Tour, and the approval process typically takes three days. Philippine travel agencies can arrange permits in advance to guarantee entry on the desired tour date.
