Is it right for you?
UN 13,256 (once listed as UN 13,260 D) is a low-key tundra summit north of Coney Benchmark, above the old Carson townsite. It's usually done with Coney as an easy family day.
From Coney you drop north to the Colorado Trail, or use a higher side trail, and follow it toward the peak. Past a small sub-peak to the southwest, you leave the trail and walk up to the top. Expect a few boulders just below the summit; the rest is tundra. It's Class 1.
The round trip, including Coney Benchmark, is about 7 miles with 1,775 feet of gain. From Coney's summit it's about 1.5 miles and 400 feet one way.

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
Carson Pass
From Lake City, head south on Highway 149 and turn right on County Road 3 (BLM 3306, shown as CR 30 on some maps) toward Lake San Cristobal. It's paved past the lake, then turns to good gravel that any car can drive. About 2 miles beyond Williams Creek campground, turn left (south) onto the Wager Gulch road (BLM 3308 or FS 568), signed for the old Carson townsite.
From that turn, plan on 4WD with good clearance. The road climbs through aspen and evergreens, steep in spots, to the Carson ruins. Above Carson it gets rockier and runs through willows for about the last mile to Carson Pass at 12,370 feet. Recent grading has made it easier, but it is still slow, and conditions change. If the top part makes you nervous, park near Carson and walk up.
You'll find Forest Service campgrounds at Mill Creek, Williams Creek and Lake San Cristobal. Wager Gulch has a few level primitive spots; a good one is a meadow on the west side of the road just before the Carson turnoff, near 11,240 feet. Beetles have killed many trees around it, so check above your tent before you pitch it.
