That's not entirely accurate. While Mt. Kailash in Tibet is a sacred mountain that has never been scaled by climbers seeking to conquer its summit, there have indeed been some attempts and successful climbs of the mountain.

The first confirmed ascent of Mt. Kailash was made in 1889 by a British surveyor, F.M. Bailey, but his climb was not without controversy. However, it is worth noting that local Tibetan pilgrims and monks had climbed the mountain for centuries prior to this event.

Since then, several climbers have successfully summited Mt. Kailash, including Chinese and Nepali mountaineers. However, these climbs were often made without the knowledge or consent of the local authorities or indigenous communities, which has contributed to controversy and debate surrounding tourism on the mountain.

It's also worth noting that many people choose not to climb the mountain, instead opting for spiritual pilgrimages around the sacred site, which is believed by Buddhists, Hindus, Jains, and other faiths to be a place of great spiritual significance.
