Park at the ever-cold (even in summer!) Col du Lauteret and skin north, climbing up to a snow-covered jeep track. Follow this jeep track as it takes you into the peaceful valley immediately north of the Montage de Chaillol. Stay on the jeep track until it begins to double back on itself, at which point you need to leave the track and continue skinning north-west, heading directly towards the Pic des Trois Évêchés.

The bowl you skin up is fairly mellow but as you get closer to the peak it begins to kick up and becomes increasingly steep. Depending on conditions you may need to bootpack but if the snow is soft, you should be able to keep skis and skins on. The slope eventually crests the Pic des Trois Évêchés's south-west ridge at a spectacular hanging col. 99% of ski tourers call this col their high point and choose not to go to the mountain's summit. If you do want to tag the top it involves covering some pretty technical terrain and is reserved for experienced mountaineers only.

The col has a pretty wild feel so pause for a while to enjoy it. When you get too chilly (and you probably will because it's an exposed spot) put skis on and retrace your steps back to the Col du Lauteret via some fun skiing and excellent views.
