Hiunchuli is a peak in the Himalaya of central Nepal. The mountain is an extension of Annapurna South. Hiunchuli, situated at the height of 6,441 meters, forms a massive south-facing wall together with Annapurna South. Its eastern face overlooks the Modi Khola and guards the entrance to the Annapurna Sanctuary. An American Peace Corps Expedition, via the southeast face, first climbed Hiunchuli in October 1971. The mountain is not technically difficult to climb but is vulnerable to rock falls, and route finding may also be a problem. Even though it offers major new route potentials, it has received little attention from mountaineers and is rarely climbed.
