A complete “mountain to sea” ecosystem, this karst landscape in the Philippines has the sole underground river in the world that flows out directly to the sea. This unique topography subjects the lower part of the underground river to tidal influences – a remarkable natural phenomenon that has no equal elsewhere across the globe.
The Puerto Princesa Subterranean River National Park is part of the bigger UNESCO-led Palawan Biosphere Reserve that was established in 1990. The park was also declared as a UNESCO World Heritage Site in 1999, and, in 2012, it was also proclaimed as one of the Seven New Wonders of Nature though a global popular poll.
These, my friends, are the real bragging rights of this natural gem in Palawan, the Philippines.
