Puerto Princesa Underground River Tourism

The Puerto Princesa Subterranean River National Park in Palawan, Philippines, is a UNESCO World Heritage Site renowned for its spectacular limestone karst landscape and its navigable, underground river. Situated about 50 kilometers north of the city of Puerto Princesa, this impressive natural wonder is also listed as one of the New 7 Wonders of Nature. The river flows directly into the sea, and its lower portion is subject to tidal influences, which makes it a significant natural phenomenon. This park is also notable for its biodiversity conservation, harboring many species of birds and animals, including some that are endemic to the area. With its striking cave formations, stunning geological features, and distinctive ecosystem, the Puerto Princesa Underground River is a premier eco-tourism destination. Exploring the cave system on a guided boat is a surreal experience where you can witness stalactites and stalagmites, as well as several large chambers, and plenty of bats. The park is not only a natural treasure but also an important archaeological site, with limestone cliffs dating back millions of years.
