Harding Icefield Trail

The feel

The trail starts on the valley floor and winds through cottonwood and alder forests and heather meadows before it climbs well above tree line to a view of the Harding Icefield. It is a strenuous climb, gaining approximately 1,000 feet of elevation with every mile. Black bears are spotted almost every day from the trail, and mountain goats and hoary marmots have been seen as well. Marmot Meadows and Top of the Cliffs are good shorter turnaround points with scenic views.

What to expect

Route and terrain

Out and back of 7.8 to 8.2 miles with about 3,500 ft of gain, through forest and meadows to above tree line. Marmot Meadows is 1.4 miles one way and Top of the Cliffs is 2.4 miles one way, both good places to turn around.

Time

At least 6 to 8 hours.

Parking

Turn onto Herman Leirer Road at mile 3 of the Seward Highway and go 8.4 miles to the nature center lot. Walk down the paved trail to the trailhead.

Fees and passes

No activity fee and no reservations.

Dogs

Not allowed; no pets on trails.

Hazards

Black bears are common, so carry bear spray and make noise. Expect storms, high winds, intense sunlight, sudden temperature changes.

Cell signal

No cell service in the area.

Bathrooms and water

No toilets or water on the trail. Carry at least 2 liters of water per person, or treat stream water, which may contain Giardia.

Season and access

The upper trail is often covered with snow through early July, with avalanche danger. In winter and the shoulder seasons (Oct, Nov, May, Jun) it is a mountaineering route.

Mingo says

Wait until July for the upper trail, once the snow and avalanche danger ease. Pick Marmot Meadows as your turnaround if you want a shorter day.
