Cordillera Huayhuash Circuit

Cordillera Huayhuash Circuit

One of the world’s great high-Andes treks: a 130km loop of turquoise lakes, 6,000m peaks, and high passes. The route demands fitness, acclimatization, and self-sufficiency—or a good mule-supported logistics team.

Complete planning — acclimatization, camps, transport via Huaraz, and weather strategy — is in the Wakahi Guide.

• Distance: 130km (circuit)
• Duration: ~12 days
• Category: Mountain Track
• Difficulty: Very Challenging
• Elevation gain: ~5,500m+
• Season: Season dependent (typically dry season winter months)

Overview

Stage-to-stage the circuit crosses multiple 4,700–5,000m passes with constant views of Yerupajá, Siula Grande, and Jirishanca. Lakes glow electric blue below hanging glaciers; nights are cold and crystalline.

History and Cultural Context

Quechua communities graze high pastures and maintain access trails; mountaineering history (including the Siula Grande “Touching the Void” story) echoes through these valleys. Respect community camps and local fee stations.

Seasonal Highlights

Dry season (roughly May–Sept) offers clearer skies and colder nights; shoulder periods can bring unsettled weather and snow on passes. UV is high year-round at altitude.

Suggested Itinerary

• Day 1–2: Trailhead approach and first high valley camp — slow start for acclimatization.
• Day 3–5: Crossing early high passes with lake vistas; optional mirador detours.
• Day 6–8: Core alpine stages beneath Yerupajá/Siula Grande; big days, big views.
• Day 9–11: Remote valleys and final passes; contingency buffer for weather.
• Day 12: Exit to roadhead and return to Huaraz.

Planning and Logistics

• Acclimatize in Huaraz (and do a warm-up hike) before starting.
• Expect community fees at checkpoints—carry small cash.
• Mule support eases load; unguided parties must be fully self-reliant.
• Water treatment, sun protection, and cold-weather sleep systems are essential.

Around Huaraz

• Laguna 69 or Pastoruri acclimatization hikes
• Local markets and Andean cuisine
• Mountaineering museums and gear shops

Safety and Conditions

• High altitude risks (AMS/HACE/HAPE) — ascend gradually and know symptoms.
• Cold, wind, and snow possible any month; robust layers and shelter required.
• River/stream crossings after storms may be serious.
