The best time to visit is during the dry season, from November to May. These months offer sunny weather and calm seas—ideal for tours and beach activities. June to October is the rainy season, which may cause tour cancellations.
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.
