Ancohuma is the highest peak in the Sorata Massif, towering on the remote northern edge of the Cordillera Real. It was not climbed until 1919 and remains a challenging climb that should only be attempted with a guide for all but the most experienced of mountaineers.

For a long time, various sources put Ancohuma at around 7000m, which would have made it higher than Argentina’s Aconcagua, but in 2002 an American student lugged GPS equipment to the top and determined its true height to be 6427m, about 100m short of Bolivia’s highest mountain, Sajama.
