Veronica Mountain, Mountain summit in Cusco Department, Peru

Veronica Mountain rises to 5,893 meters in the Urubamba range and is marked by its snow-covered peak visible from the Sacred Valley below. The mountain features steep slopes and varied rock formations that create a complex geological structure across its terrain.

Lionel Terray, Geoffrey Egeler, Tom de Booy, Raymond Jenny and Eliseo Vargas made the first ascent in 1956 via the mountain's north side. Richard Toon and Tom Hendrickson climbed the south side in 1974. In 2009 Alfredo Zúñiga and Jorge Sirvas, of the Cusco mountaineering club, completed the first all-Peruvian ascent after three days, opening a variant of Terray's route.

The mountain carries several Quechua names: Waqaywillki, Wayna Willka and Waqaywillka, while English sources also record Huacrahuilki, glossed as "horn pass". Spanish speakers call it Nevado Verónica, and it is also known as Padre Eterno. Its southwest face is visible from the Inca Trail and from the windows of the Cusco–Machu Picchu train.

Visitors reach the mountain via Ollantaytambo and need professional guides plus proper high-altitude climbing equipment for the ascent. Planning time for acclimatization before attempting the climb is important, as the peak sits well above 5,800 meters.

In 2005 an ice and rock fall from the mountain turned into a debris flow in the Runtumayo gorge, partly damming the Urubamba river and damaging about 400 metres of railway line, farmland and irrigation and drinking-water systems, with no casualties reported.
