Puerto Princesa Subterranean River National Park

According to the UNESCO World Heritage Centre, the Puerto Princesa Subterranean River National Park features a spectacular limestone karst landscape with an underground river. One of the river's distinguishing features is that it emerges directly into the sea, and its lower portion is subject to tidal influences. The area also represents a significant habitat for biodiversity conservation. The site contains a full 'mountain-to-sea' ecosystem and has some of the most important forests in Asia.

1. From the Ninoy Aquino International Airport in Manila, take any plane to Puerto Princesa Airport (Philippine Airlines, Cebu Pacific Air, Airphil Express, ZestAir).

2. Rent a van to take you at the jump-off point to the underground river. Rental ranges from 2500-3000pesos. But before proceeding to the jump-off point, register at the city tourism office. [I forgot the fee]

3. At barangay Sabang, give the permit to the office. You will then pay for a banca to the river (cost is 750pesos).

Considering the fact that you go there only for the underground river, the cost is expensive, especially for small-time backpackers. Other interesting activities include Honda Bay beach-hopping, city tour and hunting for affordable souvenir items at Tiangge! You can also eat at restaurants like Badjao and check for yourself their delectable seafoods.
