Yerupajá is a mountain of the Huayhuash mountain range in west central Peru, part of the Andes. It's located at Áncash, Bolognesi Province, Lauricocha Province. At 6,635 metres it is the second-highest in Peru and the highest in the Huayhuash mountain range. The summit is the highest point in the Amazon River watershed, and was first reached in 1950 by Jim Maxwell and Dave Harrah, and its northern peak in 1968 by the Wellingtonian Roger Bates and Graeme Dingle. Many visitors consider Yerupajá to be the most spectacular peak in South America.
There have been only a few successful ascents of the peak because it is one of the hardest Andean high peaks to climb. The most popular route is the southwest face. The approach is normally made from Huaraz southwards via Chiquián and Jahuacocha.
