There are many climbing routes that are opened by ski patrol from time-to-time, but the safest and easiest way to the summit is to take the Peak 8 Colorado Superchair to the base of Horseshoe Bowl. Then traverse south toward Chair 6. Take Chair 6 to the Imperial Superchair. At the top, you'll see the climbing giude-ropes - follow them to the top - about a 20 minute hike.
