"First time and last time summiting Longs Peaks. Incredible hike, but I'm not crazy enough to do that twice!"
Mordecai Vlanch
"Great hike. Went in late September and made it only to the keyhole due to snow, ice and wind conditions on top. The route is pretty challenging in the upper sections and requires scrambling from time to time. The views are spectacular and worth the effort."
