A camping traverse through the Cordillera Blanca
The Santa Cruz Trek crosses part of Huascarán National Park in Peru’s Ancash region, linking Vaquería and Cashapampa through the Cordillera Blanca. The classic route is about 50 km long and is normally walked as a camping trip over three to four days. Its defining terrain is a sequence of glacial valleys, lakes and streams beneath high Andean peaks, including Taulliraju, Alpamayo, Artesonraju and Huascarán. This is a valley trek with a substantial high pass, rather than a summit climb. The surrounding range contains several mountains above 6,000 metres, giving the walk a high-mountain setting throughout. Plan around carrying or arranging overnight equipment and organizing transport at both ends, rather than treating it as a series of day walks.
Punta Unión and choosing a realistic pace
Punta Unión, at 4,750 metres, is the trek’s central planning consideration. The route’s roughly 50 km length matters, but altitude deserves equal attention when deciding whether the itinerary suits the group. Most hikers take four days and three nights; a three-day crossing is an option for hikers who are already acclimatized and fit, not a useful default for everyone. Allow time to adjust to altitude before starting, and avoid building a schedule that depends on maintaining a low-elevation walking pace. Camping equipment, warm layers and protection from changing mountain weather belong in the plan. The lakes and streams are part of the route’s landscape, but their presence should not replace a considered drinking-water treatment plan for a multiday walk.
Trip organization and the wider mountain landscape
Huaraz is a base for organizing the trek, with access and return transport arranged through Huaraz, Yungay and Caraz. The walk can be undertaken independently or with a guide, cook and pack animals arranged through agencies in Huaraz. Choose the level of support according to the group’s experience with high-altitude camping and carrying overnight loads. Beyond the trail itself, the Cordillera Blanca runs parallel to the Santa River valley, known in its upper and middle sections as Callejón de Huaylas. Huascarán National Park encompasses almost the entire range. Glaciers are a defining feature of these mountains, and their snowmelt contributes to northern Peru’s year-round water supply. That wider setting makes careful camp practices and protection of streams especially important.
