A road leads over a pass near the peak at the Col du Ballon d'Alsace, 1,171 m (3,842 ft). The pass is noted as the site of the first official mountain climb in the Tour de France on 11 July 1905,[4] the first rider to the top of the climb being René Pottier and the stage being won by Hippolyte Aucouturier. Stage 9 of the 2005 Tour crossed this pass on the centenary of the original climb.
Ballon d'Alsace features Alpine and Cross Country skiing tracks.
The mountain is part of the so-called Belchen system, a group of mountains with the name "Belchen" (in German) that may have been part of a Celticsun calendar.
