Highway 6 is a 72 km long route that runs in southwestern Alberta, extending from the junction along Highway 3 (Crowsnest Highway) north of Pincher Creek to the Canada–U.S. border at Chief Mountain. As it travels south, it passes through Twin Butte and intersects Highway 5, which is the main route into Waterton Lakes National Park. Highway 6 then continues along the park's eastern boundary towards the international border where it enters Glacier National Park in Montana as State Highway 17.
