This popular, 11,749-foot peak rises dramatically above the Utah Valley and offers hikers a challenging—and picturesque—climb to its rugged summit. Get an early start and prepare for a 10-hour day of hiking.
From the campground at Aspen Grove, hike west into the Primrose Cirque. The trail switchbacks six times up the slopes of the cirque, then traverses to the southwest for a 22-switchback climb beneath Roberts Horn. The trail skirts Hidden Lakes and continues to ascend to the northern edge of Emerald Lake. After 5.5 miles, traverse the barren slopes above Timpanogos Basin and crest the Mount Timpanogos ridgetop. Follow the narrow ridge south to reach the windy summit (the second highest peak in the Wasatch). Look to the southwest for stunning views of Utah Lake and Utah Valley, then follow the same route back to the trailhead.
Caution: The return trip to the trailhead descends a steep, seasonal snowfield southwest of the Timpanogos summit. Do not attempt this if you are uneasy in snowy descents.
