Climbing the West Slopes
From Alma, Colorado, take Highway 9 north and turn onto Kite Lake Road. Follow the rough road to Kite Lake trailhead. Often done as part of the famous Decalibron loop with Democrat, Cameron, and Lincoln. Check current access status as there have been closures due to private property issues on the summit area. Loose rock and strong winds are common on the exposed ridges. Class 2 terrain throughout. The loop is a popular way to bag four 14ers in a single day. Start early for weather. High clearance vehicle recommended for the road.
