The town is situated at the foot of the Cottian Alps, near Monviso and more precisely, in a basin at the foot of Mount Bracco and Mount Medìa. The inhabited centre is crossed by two streams (Chiappera and Infernotto), which join to form a third one, the Ghiandone, which joins the river Po near Staffarda. Barge lies about 360-390 metres above sea level.
