Boulder, Colorado is a climbing mecca, and its crags are steeped in history. Here you'll find everything from bolt-protected clip-ups, run-out test pieces, 1,000 ft. cruiser slabs, and a healthy dose of hard boulders. The sheer concentration and variety of rock make Boulder a world-class destination for any level of rock enthusiast.

 Boulder Climbing Community

"Every year a variety of local crags are closed to protect nesting raptors. As climbers, we should see it as a privilege that we can share these few crags with our winged friends, and an honor to let them have solitude to reproduce. It is only for half of the year, on a small fraction of the available nearby climbing terrain.
Please help spread the word: do not climb on these formations during the closure period! As the season progresses and it is known which nesting sites are active, some of these formations are re-opened to climbing before the deadline."
