The Elk Range near Aspen holds some of the most dramatic peaks in the Rockies, including Capitol Peak with its exposed Knife Edge and the Maroon Bells, whose crumbling sedimentary rock earned them the name the Deadly Bells. Their summits reward careful, experienced scramblers.
In season: Jul–Sep · Peak: Aug
Class 3 and 4 scrambling on steep, loose rock, with exposure, rockfall and route-finding challenges. Start before dawn to be down before the afternoon lightning.
The hardest standard fourteener route in Colorado

Steep scree and exposed scrambling above Aspen
Climb easier fourteeners elsewhere in Colorado first, and learn to move on loose rock. Get the overnight wilderness permit, camp at Capitol Lake for Capitol Peak, wear a helmet, and consider a guide for the Maroon Bells traverse.
