With peaks, lakes, and waterfalls, this trail is steep in parts, but always scenic and worth the push.

The trail first takes you to Upper Blue Reservoir, about 1.4 miles in. Past this point, it can be somewhat tricky to find the trail, but for experienced hikers, the upper valley holds a number of lakes, a waterfall, and open tundra for exploring. Mountain goat sightings are also common in this area, so keep an eye out!

Hike McCullough Gulch to Upper Blue Reservoir Reviews

Beautiful hike, but this lake is not actually called Upper Blue Reservoir, and at this time has no official name. There was an error in the US Geographic Names Information System (GNIS), which incorrectly put Upper Blue Reservoir on the north flank of Quandary Peak, south of this lake. This reservoir is actually in Monte Cristo gulch south of Quandary. I reported the error, and the coordinates have since been fixed. See https://geonames.usgs.gov/apex/f?p=138:3:::NO:3:P3_FID,P3_TITLE:199759,Upper%20Blue%20Lake

My first, and favorite, hike I've done in Colorado!
