At an altitude of 2329 metres, the Col du Bonhomme links the Val Montjoie to the Beaufortin, and Haute-Savoie to Savoie. It is one of the passes crossed by the GR 5 trail, the Tour du Mont Blanc and the Tour du Beaufortin.
Thanks to its strategic location, this pass has been a crossing point for Romans, peddlers, crystal smiths, and livestock merchants throughout history... In 1860, when Savoie and the Comté de Nice were annexed by France, a free trade zone was established over a large part of northern Savoie, with the pass as one of its boundaries.
