Well known to cyclists in the region, the Col de la Croix-de-Part rises to 811 meters above sea level. It is the starting point for several hikes and has a parking lot.

When the weather is clear, it is possible to see Lac du Ronzey to the east. In winter, the climate can become harsh in this place, with patches of ice.
