Alain Mesili
Alain Mesili is a renowned French-Bolivian mountaineer, author, and explorer celebrated as the founding father of modern technical climbing in Bolivia. Known affectionately as the Frenchman of the Andes, Mesili pioneered over 50 daring first ascents across the Cordillera Real during the 1970s and 1980s, including the West Face of Huayna Potosí and the South Face of Illimani.

Biographical Record & Archival Chronicle
Born in France, Alain Mesili was captivated by high mountains from his youth in Chamonix, honing advanced ice and big-wall techniques in the Mont Blanc massif. In the late 1960s, seeking pristine, unclimbed walls away from the crowds of Europe, Mesili traveled to South America and settled in La Paz, Bolivia. Mesili quickly recognized that the Cordillera Real held world-class alpine potential that remained untouched by modern technical methods. Over the next two decades, Mesili launched an extraordinary series of bold first ascents. In 1970, he spearheaded the first direct ascent of the daunting 1,000-metre West Face of Huayna Potosí (6,088 m), tackling 70-degree black ice and vertical mixed pitches. In 1972, Mesili solved one of the grandest challenges in South America by completing the first direct ascent of the colossal 2,000-metre South Face of Nevado Illimani (6,438 m). Mesili went on to establish technical routes on Mururata, Condoriri, and Chachacomani, authoring the first comprehensive modern climbing guidebook to the Cordillera Real, The Bolivian Andes. Mesili dedicated his life to training Bolivian mountain guides, promoting sustainable alpine tourism, and advocating for environmental protection of the fragile Altiplano watersheds.

Illimani
Nevado Illimani is the iconic 6,438-metre monarch of the Cordillera Real, towering dramatically over the city of La Paz and the Bolivian Altiplano. First climbed in September 1898 by British explorer Sir William Martin Conway alongside Swiss guides Antoine Maquignaz and Jean-Antoine Pellissier, the mountain features four distinct summits linked by knife-edge glaciated ridges. Its immense southern and eastern faces drop precipitously toward the Amazon basin.
Huayna Potosí
Huayna Potosí is a stunning 6,088-metre glaciated pyramid in the Cordillera Real of Bolivia, widely regarded as one of the most aesthetic peaks in South America. First climbed in 1919 by German mountaineers Rudolf Dienst and Adolf Schulze, the peak features classic glacier ramps, steep summit bergschrunds, and formidable 1,000-metre technical ice walls on its west face. It stands directly north of La Paz near the Zongo Pass.

Huayna Potosí French Route (Southeast Face)
The French Route on Huayna Potosí is an exhilarating technical ice direct ascending the peak's southeast wall to 6,088 metres in the Cordillera Real. First climbed in the 1970s by French-Bolivian alpine pioneer Alain Mesili and companions, this direct variant surmounts a continuous 300-metre ice wall sloping between 55 and 70 degrees, bypassing the crowded normal route to deliver a thrilling and pure alpine experience.
Illimani South Ridge Normal Route
The South Ridge Normal Route of Nevado Illimani is the classic high-altitude line ascending the southern monarch of the Cordillera Real to 6,438 metres. First climbed in September 1898 by Sir William Martin Conway and Swiss guides Antoine Maquignaz and Jean-Antoine Pellissier, the route traverses hanging glaciers and the famous Nido de Cóndores aerie before conquering an exposed 50-degree knife-edge summit arête.

1970 Mesili Huayna Potosí West Face Historic Direct Ascent
In July 1970, French-Bolivian alpine pioneer Alain Mesili and climbing companions unlocked the colossal 1,000-metre West Face of Huayna Potosí (6,088 m). Scaling 70-degree black ice corridors, rotten quartzite bands, and hanging seracs in lightweight style, their breakthrough inaugurated modern extreme technical alpinism in the Cordillera Real.
1972 Mesili-Monasterio Illimani South Face Historic Direct Ascent
In August 1972, Alain Mesili and elite companions completed the first direct ascent of the terrifying 2,000-metre South Face of Nevado Illimani (6,438 m). Confronting relentless vertical ice flutings, stonefall, and hanging bivouacs suspended over the Amazon basin, the team conquered the greatest high-altitude big-wall ice face in Bolivia.
