Things to Do at Puerto Princesa Subterranean River National Park

The Puerto Princesa Subterranean River National Park, also known as the Underground River, is a UNESCO World Heritage Site and one of the New 7 Wonders of Nature. Located in the Saint Paul Mountain Range on the western coast of Palawan, this remarkable natural wonder features an 8.2-kilometer navigable underground river that winds through a spectacular limestone karst landscape. The river flows directly into the South China Sea and is believed to be the longest navigable underground river in the world. The park encompasses 22,202 hectares of pristine old-growth forest and marine ecosystems, serving as a habitat for numerous endemic species. Visitors can explore approximately 4.3 kilometers of the underground river system aboard a paddle boat, marveling at the cathedral-like chambers adorned with impressive stalactites and stalagmites formations. The park's rich biodiversity includes over 800 plant species, 165 bird species, and various mammals, making it not only a geological marvel but also an important conservation area.

From Puerto Princesa City, take a 1.5-2 hour drive north to Sabang via the national highway. Most visitors join organized tours that include round-trip transportation, or rent a van/car. Alternatively, take a public bus or van to Sabang from the city center. The final approach to the underground river requires a 15-minute boat ride from Sabang wharf to the cave entrance. Some tour packages also offer a scenic route combining land travel one way and island hopping boat trip the other way.
