Fletcher Mountain Route Guide | A Fun Class 2 Climb

Fletcher Mountain 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 below. Safe travels on the trail!

Fletcher Mountain Route Guide - Southeast Ridge

My Fletcher Mountain Route Guide begins at the Blue Lakes Trailhead.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!

Hiking, scrambling and climbing up Colorado’s high peaks are inherently high-risk, dangerous activities. There is a significant risk of injury or death, even with proper planning and experience. Those using my Fletcher Mountain route guide accept all risks associated with climbing 14ers and do not hold this website or any information they obtain from it liable for any accidents or injuries that occur while engaging in these activities on Colorado’s high peaks. It is each hiker or climber’s responsibility to research their route carefully, bring the ten essentials, and practice other safe practices, though even these precautions do not eliminate risk and danger. Visit these summits at your own risk.
