Puncak Jaya

Puncak Jaya, also known as Carstensz Pyramid, is the highest mountain in Indonesia at 4,884 meters, located in the Sudirman Range of Mimika Regency, Central Papua within Lorentz National Park, a UNESCO World Heritage Site. It is the highest peak in Oceania and one of the Seven Summits. Notable for its equatorial glaciers and alpine rock faces, it attracts experienced mountaineers despite its remote tropical location.

Visitors can expect a remote, high-altitude alpine environment with steep limestone rock walls, snowfields and equatorial glaciers surrounded by dense tropical forest at lower elevations. The summit area is accessible only by technical mountaineering expedition with guides and porters. Base camps are set on rocky terrain near the Yellow Valley. Views include glaciated peaks, rugged ridges and cloud-covered valleys. No developed tourist infrastructure exists at the summit.

First sighted by Europeans in 1623 by Dutch explorer Jan Carstensz, after whom the pyramid is named. The summit was first reached on 13 February 1962 by an expedition led by Heinrich Harrer. The peak lies within Lorentz National Park, established as a protected area and later inscribed as a UNESCO World Heritage Site.

The mountain is known as Nemangkawi in the Amungme language and holds cultural significance for indigenous Amungme and other highland communities of Central Papua. The surrounding Lorentz National Park area is recognized for its cultural and natural heritage values.
