Off the Hwy between Sicamous and Revelstoke. Relatively short drive on Forestry Road. Easy to find.
Steady climb through the beautiful forest, then the alpine. The views are supposed to be spectacular, unfortunately, when we went it was pretty wet and foggy. There's a cool little hut at the top to warm up or even spend the night. (Not part of ACC). Between an hour (very fit) to 2 hours to the top depending on fitness level. More if you like taking breaks and pictures.
