Puerto Princesa Subterranean River National Park
Listed as a UNESCO World Heritage Site in 1999 and protected by the Ramsar Convention since 2012, the Puerto Princesa Subterranean River National Park has become Sabang’s most famous destination that draws scores of tourists each day. At 8km in length, the river is one of the world’s longest underground waterways with various ecosystems from the mountain-to-the-sea, including limestone karst landscapes, mangrove forests, tropical rainforests, freshwater swamps, and even a complex cave system. Day trippers can explore the park by unmotorised paddle boat tours that take you upstream into the cave about 1.5km where you can marvel at dramatic stalactite and stalagmite formations. During the cave visit, keep your mouth shut as there are many bats and swiftlets fluttering above.
