The stage from the Cabane de Chanrion (2462 m) to the Cabane de Bertol (3311 m) is one of the longer and most varied sections of the historic Haute Route. It leads through the wide glacier landscape of the Glacier d’Otemma, over the Col du Petit Mont Collon and the Col de l’Évêque into the upper Val d’Arolla. After an extended glacier descent, a last long climb awaits to the spectacularly sited Cabane de Bertol.
The route links several large glacier basins and passes through an impressive high mountain landscape between the Petit Mont Collon, Mont Collon and the striking rock pyramid of L’Évêque. With several climbs and descents and a total of around 1200 to 1700 m of ascent, depending on the line chosen, this stage makes high demands on fitness and alpine experience.
