Among rock cliffs and hoodoos alongside the Milk River, this park contains the largest concentration of native petroglyphs on the North American plains. Today a campground and restored Mountie outpost are here. You can explore the coulées (gullies) that provided cover for outlaws and illegal whiskey traders. Guided walks explore some of this history. The park is about 100 km (62 mi) southeast of Lethbridge. Free.
