Mount Gangkhar Puensum is in the Himalayas and is widely regarded as the world’s highest unclimbed mountain.
Gangkhar Puensum rises to approximately 7,570 metres on the disputed Bhutan–China border. Its name is often translated as “White Peak of the Three Spiritual Brothers.” The summit is part of the Himalayan mountain system, though mapping and the exact border position have been subjects of disagreement.
Bhutan restricted mountaineering above 6,000 metres in 1994 because of spiritual beliefs, then banned mountaineering entirely in 2003. Several expeditions attempted the mountain before the restrictions became decisive, but none reached the summit. This makes Gangkhar Puensum distinct from other high Himalayan peaks: its status reflects both technical challenge and national policy. The mountain is sometimes listed at slightly different elevations because surveying the remote border region is difficult.
