Flagstaff Professional Reviews and Guides
"Flagstaff Mountain has a different feel from Green Mountain and Bear Peak, partly because it is smaller in stature, partly because a road goes to the top, and partly because—given the other two factors—it is more heavily traveled. It is a better-known destination for road cyclists, and the trail to the top crosses the road in five different places, each way, so runners can race bikers."
--Adam W. Chase, Nancy Hobbs, Peter Jones , Best Trail Runs: Denver, Boulder, & Colorado Springs (Falcon Guides).
"Test your climbing prowess on the switchbacks of Flagstaff Mountain, and achieve a bird’s-eye view of the little town below."
--Robert Hurst, Best Bike Rides Denver and Boulder (Falcon Guides).
