More About This Card

The Puerto Princesa Underground River, located in the picturesque province of Palawan, Philippines, has garnered international recognition for its ecological and geological significance. In 1999, it was designated as a World Heritage Site by UNESCO, acknowledging its outstanding natural beauty and its importance to biodiversity conservation. This impressive subterranean river flows directly into the sea, merging freshwater with saltwater and creating a unique natural phenomenon. Its complex ecosystem hosts a variety of wildlife, including several species endemic to the area.

Encased within the St. Paul Mountain Range, the river winds underground for more than 8 kilometers, though only a portion of it is accessible to tourists. The cave system itself is rumored to extend up to 24 kilometers deep into the mountains, with its limestone karst landscape featuring large chambers and significant formations of stalactites and stalagmites. Tours of the cave are conducted on small paddle boats, allowing visitors to experience the eerie and breathtaking beauty of its cavernous spaces, where darkness is illuminated by the flashlights of guides, revealing rock formations that have been shaped over millions of years.

The designation of the site as one of the New Seven Wonders of Nature in 2012 further increased the river’s profile as a crucial natural treasure. This recognition brought with it a heightened interest from both international tourists and global conservationists. The Philippine government has instated various measures to preserve the delicate balance of the river’s ecosystem, focusing on protecting the area from the adverse impacts of tourism and maintaining its natural integrity.

The Puerto Princesa Underground River stands as a testament to the awe-inspiring beauty of nature and the ongoing efforts needed to preserve such irreplaceable sites. For those fortunate enough to navigate its dark, mysterious waters, the experience is nothing short of magical, providing a poignant reminder of the natural wonders our world holds and the responsibility we share in safeguarding them for future generations.
