Ujung Kulon National Park

Ujung Kulon National Park (Indonesian: Taman Nasional Ujung Kulon) is a national park at the westernmost tip of Java, located in Sumur District of Pandeglang Regency, part of Banten province in Indonesia. It once included the volcanic island group of Krakatoa in Lampung province, although current maps have suggested the Krakatoa island group as its own protected area, the Pulau Anak Krakatau Marine Nature Reserve. The area has been declared a UNESCO World Heritage Site for "containing the largest remaining area of lowland rainforests in Java", and also for possessing the most threatened species of rhino, the Javan rhino. It was designated before its formation as a national park. The park fully encompasses the Ujung Kulon peninsula, along with surrounding islands and the Gunung Honje mountain range. Ujung Kulon itself means Western End or Point West in Banten Sundanese.

Ujung Kulon National Park covers an area of 1,056.95 km2 (408.09 sq mi), of which 443.37 km2 (171.19 sq mi) is marine. Most of the park landmass lies on the mainland, specifically the Ujung Kulon Peninsula, with the highest elevation of 480 m (1,570 ft) at Mt. Payung in the southwest of the peninsula. The eastern area of the park is marked by the Honje mountain range, with several low-lying mountains and the highest peak at Mt. Honje at 620 m (2,030 ft).
