From its French side the Grand Argentier is usually accessed from Valfréjus (Modane), and is a much appreciated ski mountaineering destination. In wintertime some skilifts operating there can be used in order to shorten the climb. The normal route to access the mountain from its Italian side starts from Grange della Rho (Bardonecchia) and, after Piano dei Morti (at about 2,300 m), leaves the foothpath leading to the Colle della Rho and reaches the summit through its South-Western slopes, at first grassy and then bare and rocky, reaching the Punta Nera and finally the Grand Argentier.
