This is the standard and best-known route on Aiguille du Tour. It is a classic alpine snow-and-ice ascent with straightforward route-finding in good conditions. The main objective hazards are glacier travel, crevasses, and possible rockfall or unstable snow on the upper slopes. The route is usually climbed from Refuge Albert 1er, which gives direct access to the glacier. Difficulty is generally moderate, but conditions can change the seriousness significantly. It is commonly used as an introductory 3500 m alpine summit in the Mont Blanc Massif.
