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.
The local language is Cuyonon, but Filipino (Tagalog) is widely spoken. Most people also understand and speak basic English, especially in tourism-related services.
