Harding Icefield Trail

Harding Icefield Trail is a strenuous 7.8-mile out-and-back from the Harding Icefield Trail Register to the official end of the trail. It climbs from valley-floor forest through heather meadows above Exit Glacier, then crosses high alpine ground to a wide view of the icefield. Allow six to eight hours for the named route and about 3,100 feet of climbing to 3,527 feet. The outbound leg rises for most of its 3.9 miles, so the descent still takes work on tired legs. The trail ends at the overlook; it does not continue as a hiking route onto the icefield.

The register is about 0.6 mile from the Exit Glacier Area parking lot on a paved path. Walking from the lot and back adds about 1.2 miles, for roughly 9 miles total.

Marmot Meadows is 1.5 miles from the register, and Top of the Cliffs is 2.3 miles. Both are substantial hikes in their own right, with views of Exit Glacier and the surrounding peaks. They are useful turnarounds when you do not have the time, legs, or conditions for the full climb. Neither is the official end of the Harding Icefield Trail, which is another 1.6 miles beyond Top of the Cliffs.

The register sits near the valley floor at about 426 feet. The trail winds through cottonwood and alder forest, opening to views of the valley and Exit Glacier’s terminus. A bridge crosses a stream around 0.7 mile in; beyond it, the route steepens through dense brush and salmonberry. The climb is sustained, with little flat ground to recover on, so keep a pace you can hold for several hours.

At Marmot Meadows, heather and open ground replace much of the forest, and the view reaches over Exit Glacier to the peaks beyond. Above the meadows, the path climbs into alpine terrain and reaches Top of the Cliffs, where the glacier and mountains appear from higher up. The upper path is steeper and rockier, and lingering snow can make it slippery. Stay on the marked line: fragile alpine plants are easily damaged when hikers cut switchbacks.

The trail passes an emergency shelter at about 3.7 miles, then reaches its official end at about 3.9 miles and 3,527 feet. The shelter is for emergencies, not an overnight stop. At the end, the view opens across a horizon of ice and snow interrupted by isolated peaks called nunataks. The Harding Icefield covers roughly 700 square miles and feeds glaciers such as Exit Glacier below. For a photo, include the rocky foreground with the icefield behind it so the picture shows the scale of the view.

Snow commonly remains on upper sections into early summer, and avalanche danger or unstable snow bridges can make the higher route unsafe. Check current park conditions before leaving and follow any closure signs or orange route flags. Black bears frequent the salmonberry thickets; the park recommends carrying bear spray. There is no water or toilet on the trail, so bring enough water for the full climb and return.

Park at the Exit Glacier Area lot beside the Exit Glacier Nature Center, then follow the paved path about 0.6 mile to the Harding register. The Nature Center area has restrooms, picnic tables, and seasonal potable water, but there are no toilets or garbage cans along the trail. Summer parking can be limited around the middle of the day. Pets are not allowed on park trails.
