Though the Puerto Princesa Subterranean River National Park (PPSRNP) has a lot to offer visitors, most people make the trip from Puerto Princesa only to see the underground river, which is heavily celebrated as one of the new seven wonders of the natural world. Also part of UNESCO history, the river is now a huge source of pride to the Philippines.
The subterranean river system is 8.2km long and has several large chambers, up to 120m wide and 60m high. It flows underground almost the entire length, and empties into the ocean, so the lower part of the river is brackish (a mix of fresh and salt water) and subject to tidal influence, which makes it a natural phenomenon. When the sun is shining, the brackish water is known to turn an eye-popping bright blue-green (more green than blue).
The river isn’t the only attraction of the PPSRNP though, as the beach by the mouth of the cave features an impressive karst landscape, and the old-growth forest that fills the park is full of exotic flora and fauna. I nearly jumped out of my skin when I saw a handful of large monitor lizards crawling around, forked tongues darting about!
Since the river was given the honor of being one of the new seven wonders of nature, there was a huge jump in the amount of daily visitors, so much that a cap has been put into law for preservation reasons, which allows only 900 tourists a day into the subterranean river… but that seems to be largely flexible depending on the clout and amount of pesos you hold.
