Hike the Harding Icefield Trail
What to Expect
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
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.
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.
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.
