A Wonder of Nature | Puerto Princesa Underground River

“The Puerto Princesa Subterranean River National Park (PPSRNP) is one of the most important biodiversity conservation areas in the Philippines. It features a spectacular limestone or karst landscape that contains an 8.2 km long underground river. A distinguishing feature of the river is that it flows directly into the sea, and the lower half portion of the river is brackish and subject to tidal influence. The area also represents significant habitat for biodiversity conservation. It contains a full mountain to the sea ecosystem and protects forests, which are among the most significant in Asia.

Being able to experience one of the new 7 Wonders of Nature wasn’t just a mind-blowing expereince but an adventure worth remembering.

Also known as the Subterranean River, Puerto Princesa’s underground river is measured to be 8.2 km and the longest navigable underground river in the world, which includes stalactites (limestone formations from the cave ceiling going down) and stalagmites (formations on the ground going up) formations, and several limestones.

Each trip will take approximately 40 minutes. Once inside, you will see natural rock formations resembling animals, people, and will hear nothing but water droplets and bat noises.

Other natural wonders in the top 7 include Jeju Island, Komodo Island, Amazon Rainforest, Halong Bay, AIguazu Falls, and the Table Mountain.
