Puerto Princesa Underground River: New 7 Wonders of Nature

Puerto Princesa Underground River, also called as Subterranean River National Park, is one of the New 7 Wonders of Nature. It is a long navigable underground river. Entering into the cave is just like entering to a new underground world, mysterious and magical. There you will be amazed by how the time and erosion made the landscapes.

Puerto Pincesa Underground River is 8.2 kilometers long. It is located in Puerto Prinsesa, Palawan. The river flows directly to the sea so the river is subject to a tidal flow, a soft sailing while enjoying the views. It has formations of stalactites and stalagmites formed over thousands of years. It is a habitat of monkeys, lizards, squirrel, bats and more species.
