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.
On 30 June 1992, Edward S. Hagedorn was elected Mayor of the city and completed his three term limit of three years for every term. In November 2002, Hagedorn was re-elected as mayor of the city.
As the city was recently declared a highly-urbanized city, per Section 29 of the Local Government Code of the Philippines, it is no longer under the administrative supervision of the provincial government of Palawan, and its residents are no longer eligible to vote for provincial officials.
