Is there any climbing in the Flat Tops in Colorado?

Not really. Great spot to camp and 4wd. On the road up from Glenwood there is climbing at Windy point. Going from New Castle you pass the Pup tent and Fortress of solitude in Main elk. There is tons of potential up that way.
To answer your question I haven't seen anything besides what I mentioned.There could be rock up there somewhere.
Or if you go from the other side of Glenwood canyon from Dotsero there is Deep creek but that is a wilderness area i believe.

Thanks for the info. Coming from Edwards. I was fishing up there a few weekends back and thought it might be a way to get away from crowds this weekend.

Check out the Devils Causeway for something to do up there
