A 11.5-mile out-and-back in Alberta, with 1,351 ft of climbing. Reaches La Coulotte Peak and other summit destinations. Managed by Alberta Parks.
Most of the climbing sits in the first third — 59% of the ascent, between mile 0.0 and mile 3.8. It gives back about 4,654 ft along the way, so it rolls rather than climbing steadily.
