The Puerto Princesa Subterranean River National Park is located in the province of Palawan, and lies about 36 miles (58km) north of Puerto Princesa. Regarded as one of the New Seven Wonders of Nature, the underground river sees a significant number of tourists who can choose from many tour operators. The well-maintained National Park is part limestone karst mountain landscape, and the famed river follows a five mile (8km) course through a large cave complex that ultimately merges with the South China Sea. Visitors will enjoy a guided boat ride through the cave complex, which includes fascinating rock formations and a lively bat population.
