The World's Highest Unclimbed Mountain
At 24,981ft, Gangkhar Puensum in Bhutan, world's 40th tallest mountain, is the world's highest unclimbed mountain. Though four expeditions were attempted to reach the summit, all failed, and in 1994, the Government of Bhutan prohibited climbing of peaks higher than 6,000 meters out of respect for local spiritual beliefs. The locals regarded the mountains sacred and wished to protect them for the future generations and continuity of their culture. So though you can never climb this unclimbed mountain, you can certainly admire it and its place in Bhutanese culture by flying past it or trekking to its base.
