Hallett Peak, in Rocky Mountain National Park, is very distinctive when viewed from the east side of the park 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.
Trailhead: Bear Lake
Round trip: 10 miles / 16.1 km
Elevation: 9,475′ – 12,713′ (+3,238′)/ 2,888m – 3,875m (+987m)
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.
