Northeast Face (Cassin Route)
The Northeast Face of Piz Badile, universally known as the Cassin Route, is one of the Six Great North Faces of the Alps. First climbed in July 1937 by Italian master Riccardo Cassin, Vittorio Ratti, and Gino Esposito, who joined forces on the face with Mario Molteni and Giuseppe Valsecchi, the route ascends an unbroken 800-meter vertical shield of pristine granite slabs and dihedrals.

Tactical & Camp Notes
Requires flawless friction climbing on slab granite, efficient route-finding across deceptive slab systems, endurance over 21 sustained pitches, and knowledge of the descent over the south ridge into Italy.
Identified Objective Hazards
- •Sudden violent thunderstorms bringing waterfall runoffs and verglas across frictionless granite slabs
- •Rockfall risk in the lower approach chimneys and entry couloirs
- •Extremely difficult retreat once committed above pitch 12 due to diagonal traverses
- •Hypothermia risk during forced bivouacs on narrow sloping slab ledges
Historical Context
First climbed between July 14 and 16, 1937, by Riccardo Cassin, Vittorio Ratti, and Gino Esposito, alongside Mario Molteni and Giuseppe Valsecchi who tragically perished of exhaustion after reaching the summit.

Mountain Ascended
Piz Badile
Piz Badile is a celebrated 3,308-meter granite peak in the Bregaglia Alps on the border of Switzerland and Italy. Its name, derived from the Romansh word for shovel due to its distinctive shape from the north, is legendary for the colossal 800-meter smooth Northeast Face. This smooth sea of vertical granite slabs was first conquered in July 1937 by Italian master Riccardo Cassin with Vittorio Ratti and Gino Esposito, alongside Mario Molteni and Giuseppe Valsecchi, marking one of the Six Great North Faces of the Alps.
