Puerto Princesa is usually less affected by typhoons than other parts of the Philippines, but heavy rain may still occur. Always check weather updates and tour advisories during the June to October season.
Subterranean River Palawan
In the interest of environmental conservation, authorities restrict the number of daily visitors to the Puerto Princesa Underground River. This measure reduces disturbances to wildlife and preserves this national park for future generations. A permit is required for the Puerto Princesa Subterranean River Tour, with a processing time of about three days. Local travel agencies in Palawan can handle the permit processing in advance to secure a spot.
