What to Expect

This trail doesn't ease you into anything. You start in a coastal rainforest thick with Sitka spruce, cross a few bridges, and then the climbing begins in earnest — and it barely lets up for the next four miles. You'll push through subalpine meadows where marmots whistle at you like disapproving gym coaches, scramble over rocky switchbacks with the Exit Glacier grinding away below, and finally emerge above the treeline where the world opens up in a way that rearranges your sense of scale. The payoff is the Harding Icefield itself — a 700-square-mile sheet of ice stretching to the horizon, punctuated only by lonely rock peaks poking through like islands in a frozen sea. It looks like another planet. This is a trail for hikers who want to earn something genuinely rare, not just another pretty viewpoint.

Safety Advisory

Snow bridges and cornices persist on the upper trail through midsummer. Stay on the marked route — what looks like solid ground can be a thin snow layer over a steep drop or crevasse.

Weather changes fast and dramatically at elevation here. Temperatures can drop thirty degrees between the trailhead and the icefield, and whiteout conditions develop in minutes. Pack wind and rain layers even on a blue-sky morning.

Bears are active throughout the corridor, especially in the meadow sections. Make noise on blind corners and carry bear spray accessible on your hip, not buried in your pack.

Pro Tips

Trail Tip

Start before 9 AM — afternoon clouds regularly roll in and obscure the icefield view entirely. Morning hikers get the clear panoramas; late starters get fog.

Trail Tip

The trail crosses snowfields well into July. Bring trekking poles and wear waterproof boots with aggressive tread — post-holing through rotten snow in trail runners is a miserable experience.

Trail Tip

Stop at the 2.4-mile cliff overlook even if you plan to summit. It's the best vantage point for photographing Exit Glacier's full face, and you can see the crevasse fields up close from a safe distance.
