Birthday Peak is in the 12er family. At 12,730 feet, it sees less foot traffic than its taller cousins, which means you’ll have more solitude but still have epic views of the surrounding mountains in the Collegiate Peaks Wilderness. This hike requires some additional navigation skills and includes a fun boulder scramble to the summit. If you’re lucky, you might enjoy the company of a mountain goat or two.
Getting to the Trailhead
This hike begins at the North Cottonwood Creek Trailhead, about 8.5 miles west of the rustic town of Buena Vista. Much of the road is gravel and dirt, but easily passable in a sedan during normal summer conditions. Get turn-by-turn driving directions using Google Maps. Parking is free and no permit is required.
Hiking to Birthday Peak
There is only one trail from the trailhead, and it begins with a gentle climb that parallels and occasionally crosses Cottonwood Creek, heading towards Kroenke Lake and Browns Pass.
At 2.7 miles in, an improvised log crossing of Horn Fork Creek was the sole challenge along the Kroenke Lake Trail. There was still a lot of snow melt, so the water was running strong and I was grateful to have brought my trekking poles.
At about the 4 mile mark, I reached the unnamed creek that led up towards Birthday Peak.
Rather than follow the Kroenke Trail as it continues across this tributary and continues alongside Cottonwood Creek, we tu, ned right to follow this unnamed creek up to the cirque below Birthday Peak. Some guide books describe the trail here as “intermittent”, but there was hardly a trace in late June. This off-trail section requires good map reading skills, but as long as you follow the little creek, you will do pretty well. Having the route and maps downloaded on GaiaGPS helped tremendously.
Climbing above the tree-line, the creek grew smaller and smaller, replaced by the occasional snow field.
Soon the saddle to the south of Birthday Peak was in clear view. There were some footpaths through the snow and rock that made provided a good target as I aimed for that saddle.
At the top of the saddle, straddling the Continental Divide, looking back on what I had just climbed.
From the saddle, make your way north along the ridge to Birthday Peak. The final 0.25 miles required boulder scrambling to reach the summit. It looks more intimidating than it really is. Take your time and test each rock before putting your full weight on it.
The summit of Birthday Peak itself has a grassy knoll spotted with wildflowers. The summit register is protected by a small rock cairn.
The views from Birthday Peak are sublime.
Heading back down was easier, and I knew where I had to aim. Picking your route is much simpler when you have your GPS track to follow, and can see the area from above.
Once you reconnect with the Kroenke Lake Trail, follow it downhill back to the trailhead.
A longer, but easier route to navigate that some people prefer is to follow the Kroenke Lake Trail all the way to Browns Pass. From there, veer north and pick your way along the ridge-line, eventually reaching Birthday Peak. This adds some mileage but eliminates any bushwhacking.
