Yamanuska is one of the first mountains you see as you're heading into the Mountains from Calgary.
This is definitely not a Hike you want to miss. After about an hour on switch backs you reach the rock face of the peak. To continue on the trail you have to scale the face holding onto a chain while watching your step on the very narrow ridge.
The rest of the trail is a small trail through skree until you reach the top. The way down is the best as you get to practice your Skree Skiing!
I strongly suggest to rock some long pants or wear some gators! The way down is steep but quick as you're basically hoping down.
