Churup, Mountain summit in Huascaran National Park, Peru.

Churup is a mountain summit reaching about 5,500 meters in the Cordillera Blanca range. The mountain is defined by glacier formations, steep rocky slopes, and a turquoise lake on its southwestern side.

On 10 July 1965, Hisao Yoshikawa and Misahiko Inokuchi of the Waseda University expedition made the first ascent, reaching Churup's west summit via the south face and then the corniced southeast ridge. The mountain rises about 5,493 m at the entrance to the Quilcayhuanca valley, south of Ranrapalca.

The name Churup probably comes from Ancash Quechua: the verb tsuruy, "to freeze", or the noun tsururu, "frost, ice". The mountain stands above the Quechua-speaking villages of the Independencia District, east of Huaraz, and the two lakes at its foot, Churup at 4,450 m and Churupita at 4,584 m, carry the same name.

Vehicle transport from Huaraz reaches the Huascarán National Park entrance at the village of Pitec, about 3,800 m, where the walk begins. The roughly 6 km route climbs moderately steep slopes to about 4,500 m, passing queñual, quisuar and ichu vegetation. Allow time to acclimatise before setting out.

The name Churup probably comes from Ancash Quechua: either the verb tsuruy, "to freeze", or the noun tsururu, "frost, ice". At its foot lie two lakes, Churup at 4,450 m and Churupita at 4,584 m, both visible from the summit.
