The City of Puerto Princesa (Filipino: Lungsod ng Puerto Princesa), the capital of Palawan, is a first class city in the Philippines. According to the 2007 census, it has a population of 210,508 people in 33,306 households. It is famous for its crocodile farm, underground river and numerous dive spots. It is also the second largest city in the Philippines (after Davao City) in terms of total land area. The outlying parts of the city contain the hometown of the former House Speaker Ramon Mitra, Jr.. The Puerto Princesa Subterranean River National Park, a UNESCO World Heritage Site, features a spectacular limestone karst landscape with its underground river. A distinguishing feature of the river is that it flows directly into the sea, and the lower portion of the river is subject to tidal influences. The area also represents a significant habitat for biodiversity conservation. The site contains a full mountain to the sea ecosystem and protects forests, which are among the most significant in Asia.
