Is it right for you?
UN 13,110 is a low, easy summit at the head of Nellie Creek, in the shadow of Uncompahgre Peak. Most people here head for the 14er, so you will likely have this top to yourself.
Trails take you to a pass at 12,380 feet. From there you walk east on tundra, then break through a short band of rock to a long, flat summit ridge. The high point is at the rocky west end. It is Class 2, and young kids can do it if you can drive to the trailhead.
The round trip is about 4.8 miles with 1,680 feet of gain. UN 13,108 is an easy walk east-northeast along the same ridge, and UN 13,155 across the valley can be added if time and weather allow.

Afternoon storm risk is the line that matters. Everything else is comfort. In summer, plan to be off the ridge before the build-up starts, not as it starts. Forecast for the summit point, adjusted for its elevation · data from Open-Meteo.
Getting there
Nellie Creek
In Lake City, turn west on 2nd Street (or 3rd Street, which passes a city park with restrooms) and go two blocks to Bluff Street. Turn left (south) onto County Road 20, which runs west up Henson Creek. After 5.2 miles, turn right (north) on the signed Nellie Creek road, Forest Road 877. Regular cars should not try this road. Camping is not allowed along this part of County Road 20, but there are a few sites a short way up the Nellie Creek road.
A stock 4WD is the minimum past those first campsites. The road is rough and potholed at first, then rocky but never hard. At 2.0 miles it crosses to the west side of Nellie Creek and climbs a steep switchback. About 0.4 mile later, turn hard left (the older road going right leads toward Crystal Peak). After another mile the road levels out in a long meadow, and the trailhead is 0.8 mile farther, about 4 miles from County Road 20. Allow at least half an hour. Road conditions change, so check before you go.
The ground at the trailhead is sloped. For flatter campsites, go back about a quarter mile into the trees, or use the meadow. Uncompahgre Peak draws big crowds on summer weekends, so parking and campsites fill early.
