Inside Huascarán National Park, the Santa Cruz Trek follows an ancient mountain route between Vaquería and Cashapampa. Over four days, the trail winds through Quechua villages, open valleys and high alpine camps surrounded by some of Peru’s best-known peaks.
The crossing of Punta Unión (4,750 m) is the centrepiece of the trek. From the narrow pass, the Santa Cruz valley stretches west beneath the rock and ice walls of Taulliraju. Further along the route, an optional side trail leads towards Laguna Arhuaycocha and the pyramidal summit of Alpamayo.
We spend three nights camping in the mountains, with meals prepared at camp and pack animals carrying the camping equipment. The route is moderate to challenging, with a long ascent to the pass on day 2.
The itinerary follows the Vaquería → Cashapampa direction. The trek covers approximately 45 km, or up to 52 km with the Arhuaycocha detour. Daily distances are approximate and depend on the campsite locations and the optional excursion. The altitude profile shows walking stages, including the optional day 3 detour; it excludes the vehicle crossing of Portachuelo de Llanganuco.
