Is it right for you?
C.T. Peak is the third summit on the ridge northeast of Cinnamon Pass, facing Sunshine and Redcloud across the valley. It was once listed as UN 13,312 A.
Go over UN 13,403 and UN 13,544, then down UN 13,544's east ridge. That is the hardest part: steep outcrops with small, slippery scree. Then skirt Point 12,896 on big rubble, cross a wide tundra plateau, and walk up the southwest ridge on game trails. It is rated Class 3.
Out and back is about 9.5 miles. The 2,350 feet of gain covers the 4.75 miles to the summit; the return over UN 13,544 and UN 13,403 adds a lot more. With a second car at the Cooper Creek trailhead, you can traverse UN 13,403, UN 13,544, C.T. Peak and Gudy Peak and walk down to Cooper Creek, about 8.5 miles and 3,050 feet in all, with one short Class 3 stretch past UN 13,544.

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
Cinnamon Pass
From Lake City, go south on Colorado 149 and turn right toward Lake San Cristobal. Follow County Road 30 around the lake. Two campgrounds, Williams Creek and then Mill Creek, come before the fork at Sherman. A normal car is fine to here. Go right; higher clearance is now wise. You pass the Grizzly Gulch / Silver Creek trailhead in a bit over 3 miles and the Cooper Creek trailhead about a mile later. After the American Basin turnoff the road gets steeper and rougher. Park at the top of Cinnamon Pass or in a pullout close by.
From Silverton, head east and keep right on County Road 2 where the paved road splits just past the courthouse. It's 4.2 miles to Howardsville, 4.3 more to the old Eureka site, 3.5 more to the Burns and Grouse Gulch turnoff, and 1.1 more to the signed Cinnamon Pass road on the right. Stay on the Engineer Pass road here; don't drift left up California Gulch.
Cinnamon Pass needs 4WD with good clearance from either side, and road conditions change, so check before you go. Without it, expect a lot of extra walking. The pass has no trees, but you could sleep in a vehicle or small tent there. Campgrounds and primitive spots are lower on the Lake City side. Private land is common all through this area.
