As part of its conservation efforts, the Puerto Princesa Subterranean River limits the number of tourists each day. This measure reduces human impact on the ecosystem, ensuring future visitors can appreciate its natural beauty. A permit, which requires three days for processing, is necessary to join the Puerto Princesa Underground River Tour. Travel agencies often assist with advance bookings to guarantee access.
It’s best to drink bottled or filtered water. Tap water may not be safe for foreign travelers, especially those with sensitive stomachs.
