A nice climb with this natural bridge as a reward. When we were there (mid May) it was relatively quiet and we could take nice pictures. We spoke to a park ranger who said that it can get very busy mid summer

Wonderful rock formation over boulders; summit with a small stone pyramid and a panoramic view of all the mountains visible from here. Ascent via various routes - basically accessible from all directions. If you're looking for solitude, you're in the wrong place here, but there aren't any crowds either. It's worth it!

South Boulder Peak is one of Boulder must do runs – it's quite technical, offers amazing views and is super easy to reach from the city. Combine it with the neighboring Bear Peak for a perfect loop.

Bear Peak is quite a tough run – especially the last ascent is more scrambling than anything else. But it's worth it: The views from Bear Peak are amazing. To the east the vastness of the Great Plains and to the west the snow capped summits of the Rocky Mountains. From here it's only a short trail to South Boulder Peak summit, to add some more miles or for another perspective on the landscape.
