Fletcher Mountain Route Guide

Fletcher Peak is one of Colorado’s Centennial Peaks (the tallest 100 summits in the state). It’s one of the shortest climbs, with only 2,250 feet of elevation gain over 4.25 miles. The route holds snow late into summer, so bring an ice axe and microspikes just in case, and try it in August if you’re not a fan of snow and ice. Start planning your trip with my Fletcher Mountain Route Guide.

Fletcher Mountain Standard Route Guide

Head out from the parking lot along the shore of Blue Lake. Your aim is to follow a cairned trail up to a path higher up on the slope. This will bring you up into the upper gulch to the West of Quandary Peak. The trail is eroding significantly in areas. Stick to the main path to reduce your impact where possible.

Follow the trail to the bottom of the gully ahead of you. The clear trail ends around the bottom of this chute. When clear of snow it’s not a difficult scramble up the gully. However in summer you may run into hard, consolidated snow and ice difficult to ascend.

Once above the gully, rock hop your way across the next basin path a small lake. It’s a great spot for a break on your descent with wonderful solitude. Head for a ramp along the headwall in front of you and take a series of ledges up and out of the upper basin. There may also be snow here late into the summer.

Once out of the basin, cross a flatter area and start to scramble up the southeast ridge of Fletcher Mountain. The last few hundred feet of the climb are steep and loose, so take your time. Follow cairns to stay on the loosely defined trail up the ridge, and stay on this side of it – there are steep drop off’s to the east.

Once on the summit, enjoy your accomplishment. You’ll be able to see Quandary’s Class 3 West Ridge, along with Drift Peak to your south and Atlantic Peak to the north. Descend with plenty of time to ensure you get back to your car before afternoon thunderstorms become an issue. I hope you found my Fletcher Mountain Route Guide helpful!
