Right off Hwy 9 and just 17 km west of Drumheller, Horseshoe Canyon in the Canadian Badlands is an eye-popping sight. Stand on the edge of this huge U-shaped canyon and survey the beauty and mystery of the badlands. The maroon-striped canyon walls reveal the layers of time down to the Cretaceous period, when dinosaurs roamed a lush sub-tropical habitat some 70 million years ago. The two arms of the canyon extend approximately 5 km each. For the adventurous, pick a trail and hike to the bottom.
