Trekking
The range has become noted for trekking in the form of the Huayhuash Circuit, which is considered quite a challenge and is undoubtedly far more demanding than the famous Inca Trail in the south of Peru. Fewer people trek the Huayhuash than the nearby Cordillera Blanca. The circuit generally takes between ten and fourteen days, depending on the route taken.
Most of the walking, and most of the campsites, are above the 4000 m tree line, so the landscape appears rugged and mountainous, affording views over very wide areas. The area is noted for its spectacular glacial lakes. Hot springs can also be found in the area. Condors, llamas, alpacas and viscachas can be seen. Trekking is almost always undertaken in the dry winter months of May to September, and the cities of Huaraz and Caraz over 100 & 167 km away are the usual choice for organizing and hiring camping a/o logistical support. Chiquián was for a long time the "Gateway to the Huayhuash" but nowadays, daily buses (called locally colectivos go deep into the mountains to the village of Llamac (3300 m) and with private transport, as far as Cuartelhain camp, reached both by road built in the late 90s and 2000s, becoming now the new trail heads for starting/ending.
