The underground river in the Puerto Princesa Subterranean River National Park is the longest navigable underground river in the world and certainly one of the most beautiful—8.2 kilometers of meandering waterways that comes out into the South China Sea. The cave entrance to the underground river could be on the cover of any guidebook—a clear lagoon with jagged rocks above on which trees grow to the edge.
The park was listed as a UNESCO World Heritage Site in 1999 and chosen by over 100 million people as one of the New7Wonders of Nature along with Halong Bay in Vietnam and the Iguaçu Falls in Argentina.
