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.
While not required, tipping your guide is a great way to show appreciation. A tip of around ₱100–₱300, depending on group size and tour length, is customary.
