This is the trailhead for the 8 mile roundtrip Harding Icefield Trail. This trailhead is located off of the Glacier Overlook trail. From the Exit Glacier Nature Center walk down the concrete path towards the Glacier Overlook trial, and turn off when you see signs for the Harding Icefield Trail. From here, the trail is roughly 4 miles one way (8 miles round trip). The elevation increases to roughly 4000 feet by the trails end. The trail leads up to the Harding Icefield, which is the largest Icefield entirely within the United States. There are spectacular scenic views of Exit Glacier and the Harding Icefield along the way, especially at Marmot Meadows and at Top of Cliffs
