Ugong Rock Adventure and Puerto Princesa Underground River
Visit Ugong Rock, a 75-foot limestone formation known as Ugong Rock Cave. Make your way to the top by navigating its winding passageways, then reach the view deck, which serves as the drop-off point for the zipline. For more thrill, take the zipline going down.
Explore Puerto Princesa's primary tour destination, the World's Navigable Underground River, one of the Wonders of Nature. With its spectacular rock formations of stalagmites and stalactites, the Puerto Princesa Subterranean River National Park has become a UNESCO World Heritage Site and has also been awarded Ramsar site status.
