colorado muni trails

I’ve spent the last 2 summers riding muni in Estes Park, have done trails at Hall Ranch, Brainard Lake, Sourdough, Johnny Park, Pole Hill Road, Elk Ridge, the Homestead and Lion’s Head, as well as North St. Vrain.

I’m looking for more trails with granite like Hall Ranch and other riders to contact in the EP, Boulder area. Would like to do trials, as well as some 20-50 mile epics. Please inform.
