Tronchey's line Map

Again another easy access line, turn right on top of "Tronchey" chairlift and take the gully in front of you. The entrance is really steep above 55 degrees and required some important skiing skills as mistake can bring heave injuries. Avalanche risks is really important in this part as the area is well protected from the sun and can take a lot of snow, steepness add as well more risks. Only expert skiers in this side as this is really heavy skiing, trees are present the lower section what is guiding yourself until the end. The line finishes on the blue piste "Lac Léman (Torgon)" which leads back to Torgon ski area.



Extreme skiing terrain above 45 degrees. These routes are reserved for experienced experts.
