Really not anything like that right now, in the Winter or Spring close but not now.
You can check with:
Most, if not all the mountains in CO are day trips. You could backpack into the middle of a few and day trip from there.
There's Chicago Basin, near Durango,can be crowded. There is Eolus, North Eolus, Sunlight, and Windom 14ers to climb.
South of Westcliffe are the Colony Lakes. Crestone Peak, Needle, and Humboldt are there.
Eolus and Sunlight have a little Class 3 climbing, but the Crestones have a lot of solid Class 3 fun.
