Puerto Princesa is the lone city (along with twenty-three (23) municipalities) comprising the province of Palawan in the Mimaropa Region. The city is politically subdivided into sixty-six (66) barangays, and is a part of the 2nd Congressional District of Palawan.
The city serves as the provincial capital of Palawan, and while situated within the geographical boundaries of Palawan, Puerto Princesa City is administered independently of the island province.
Puerto Princesa is famous for its crocodile farms, underground rivers and dive spots. It is also the largest city in the Philippines, in terms of total land area.
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.
