Hallett Peak (12,713')

Hallett Peak (12,713′), Front Range

Hallett Peak, viewed from east Rocky Mountain National Park, is distinctive with it’s slanted square structure towering over the landscape. As you near the summit however, the square melts away and you are left looking at a more traditional mountain silhouette.

Rising along the Continental Divide, Hallett Peak divides Chaos Canyon to the south and Tyndall Gorge to the north.

The route to the summit first traverses the summit of Flattop Mountain on a well maintained trail. The Arapaho Indians called the Flattop Mountain corridor “The Big Trail”.

The trail was formally constructed in 1925, was rehabilitated by the Civilian Conservation Corps in 1940, and is currently listed on the National Register of Historic Places.

Trail Directions

From Bear Lake take the well maintained Flattop mountain trail to the summit of Flattop Mountain. No maintained trail reaches Hallett Peak, so cross the saddle above Tyndall Glacier and scramble up steep talus to the summit.
