If you mean the Municipality of Mens, it is the village of Mens, located in the Isère region, within the historic Trièves area, at the foot of the Mont Aiguille massif.

From Saint-Michel-les-Portes, it's about 7 km at an average gradient of 8%. The last few kilometers often reach double digits. A cruel climb if it's the last one of your day...
