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!
