The declaration of the Puerto Princesa Underground River as one of the Official NEW 7 WONDERS OF NATURE has resulted to the sharp increase in influx of visitors to the Park. To conserve it in its natural state, a carrying capacity of Nine Hundred (900) Visitors a day is currently in effect and a NO PERMIT, NO ENTRY POLICY is strictly enforced. Management highly advises that a Visitor Entry Permit (VEP) be secured in advance before proceeding to the Park.
