These surrounding giants include Huascarán at 6,768 m located 14.1 km S, Huascarán Norte at 6,655 m located 11.9 km S, Huandoy at 6,395 m located 6.3 km SW, Nevados Chopicallqui at 6,354 m located 11.2 km SE, Santa Cruz at 6,259 m located 15.2 km NW, and Pucajirca Norte at 6,046 m located 16.3 km N.
The range
Chacraraju is part of the White Cordillera, which contains 167 named peaks. The highest peak of this range is Huascarán, reaching 6,768 m and situated 14 km S of Chacraraju. Within this specific mountain range, Chacraraju holds the rank of the 14th highest peak.
Climbing routes
There are one route to the top of Chacraraju: Viva el tocino, which features 700 m of ascent, faces south, and typically takes 5 days. Historically, the first ascent of Chacrarahu Oeste was achieved on 31 July 1956 by a French expedition led by Lionel Terray using the northeast face, while Chacrarahu Este was first climbed on 5 August 1962 by another French expedition via the northeast ridge. Technical challenges often involve traversing beneath numerous snow cornices and dealing with impassable summit snow mushrooms.
Access and starting points
The mountain is accessible from the base camp at Cebollapampa near Nevado Pisco, and ascents are typically approached from the Llanganuco valley via Refugio Perú, starting from the town of Yungay.
Climate and weather
Climate estimates based on NASA POWER 2001–2020 monthly means, adjusted to the summit elevation, indicate that the warmest month at the summit is October at about -3 °C, and the coldest is June at about -5 °C. There are no months with a mean temperature above freezing at the summit. Precipitation in the surrounding area is about 450 mm a year, with December being the wettest month at about 65 mm and August the driest at about 10 mm. Typical weather hazards include extreme cold, technical ice and snow conditions, and objective dangers on steep slopes.
Best time to visit
Based on the climate data showing no months with a mean temperature above freezing at the summit and August being the driest month with minimal precipitation, the optimal time for visits and climbing attempts aligns with the dry season months when conditions are more stable.
Nature and wildlife
The environment around Chacraraju features high-altitude alpine terrain, glaciers, and sparse high-mountain vegetation typical of the Andes. The summit and surrounding areas are located within the Huascarán Biosphere Reserve, a protected area established to conserve the unique ecosystems of the region.
Guides and organised ascents
Due to the extreme height, technical difficulty, and objective danger of Chacraraju, hiring a certified mountain guide is strongly recommended. In Peru, the national mountain guide association is the Peruvian Mountain Guides Association (Asociación de Guías de Montaña del Perú (AGMP)), which is an IFMGA/UIAGM member organisation. The national alpine club is the Peruvian Climbing Federation (FEDPE). Established guiding companies working in the country include Skyline Adventures in Huaraz and Peruvian Andes Adventures in Huaraz. Permit rules require a Huascarán National Park entry ticket and a mountaineering permit from SERNANP.
Safety and preparation
Climbing at this elevation requires advanced technical mountaineering skills, proper acclimatisation, and robust equipment to handle steep ice and snow. For mountain rescue emergencies in Peru, the contact number for the National Police, which operates the high-mountain rescue unit USAM/DEPSAM, is 105. Additional contacts include the USAM Yungay base at (043) 39-3333 and Socorro Andino Peruano 24/7 at +51 943 081 066.
History and name
Chacraraju or Chakraraju likely derives from Quechua words meaning little farm or field combined with snow, ice, or mountain with snow. The mountain possesses two separate summits: Chacraraju Oeste at 6,108 m and Chacraraju Este at 6,001 m, also known as Huaripampa. The first ascent of the main west summit took place on 31 July 1956 by a French team led by Lionel Terray, followed by the east summit on 5 August 1962, marking the last conquered six-thousander in the White Cordillera at that time.
