The village is situated in the upper section of the narrow Valserine valley, nestled between high limestone cliffs to the south-east that form the first anticline of the Jura mountains and the edge of the Lajoux plateau to the northwest.
Despite its high altitude (just under 1000 m), the village is built around a crossroads of regional importance: the valley road (D991) which links Bellegarde-sur-Valserine with Les Rousses here crosses the D936 which links Saint-Claude with Geneva over the Col de la Faucille.
