Colorado 14ers: Longs Peak via Keyhole Route

This stiff but non-technical ascent leads to the highest point in Rocky Mountain National Park with unrivaled postcard views.

Trip Tools

Its blunt crown beckons above every other summit in Rocky Mountain National Park, and its massive silhouette holds a hallowed standing among summitmongers. The “easiest” and classic route, the Keyhole charges 4,800 vertical feet past Tolkienesque features such as Goblins Forest and Chasm Junction, passes through the namesake Keyhole, and demands a serious scramble up The Trough. This nearly 14-mile out-and-back can easily chew up 16 hours, taxing your legs, lungs, and mental vigor. But the high is all Colorado: alpine lakes cupped by glacial rubble, an outrageous mountain skyline, and the noblest lunch spot of your life.
