This peak is to the west of Berthoud Pass. Since this mountain is fairly easy to climb, it is ideal for beginners, families, or just anyone who has little time on their hands and wants to climb an alpine peak. Even though the hike is easy, the views are spectacular, and the peaks rise well above the timberline. The easy nature of the peak also belies their danger as severe thunderstorms and lightning strikes are prevalent throughout the summer months.

The peak is great for winter climbs as well since the trailhead at Berthoud Pass is open year round. With easy access and a high elevation trailhead, this is a good peak to climb in winter.

Getting There

The trailhead is at Berthoud Pass, which is on mile marker 243 on Highway 40. Berthoud Pass can be reached from the north and Fraser and Winter Park or from the south and Empire. The Empire exit off I-70 is exit 233 for those driving from the south. Park at the now closed Berthoud Pass Ski Resort parking lot. The trailhead is across the highway. Highway 40 is open and plowed year round allowing easy year-round access to the trailhead.

Routes Overview

The route I took was the Berthoud Pass Route. Breifly put, this route climbs west from Berthoud Pass to peak 12,391. From there, the route follows the up-and-down ridgeline over two peaks before reaching Mount Stanley. See the route page for details.

From the summit of Stanley Mountain, it is possible and highly recommended that you continue west to Vasquez Peak, assuming you have the time and energy. Click here for information on the continuation of the route to Vasquez Peak and here for the page on Vasquez Peak.

The new Trails Illustated Map; Winter Pass, Central City, Rollins Pass shows a new trail from the West Fork Clear Creek up to the Continental Divide Trail. This could then be followed east to Mount Stanley. I am not familiar with the route, but it is likely to have similar difficulty than the route from Berthoud Pass.

When To Climb

This a great little peak year round. The snow free season is late June through early October. Since the route follows the ridge-tops, avalanche danger is usually fairly low as long as you don't stray from the ridge. Highway 40 is plowed in winter allowing for quick and easy access year round.
