Sperry Chalet
What to Expect
Safety Advisory
Grizzly bears are active along this corridor, especially in the berry patches between miles two and four. Carry bear spray accessible on your chest or hip — not buried in your pack — and make noise on blind corners.
The upper switchbacks are exposed and snow-covered well into July most years. Early-season hikers should bring microspikes and check trail status reports, as the final mile to the chalet can be a steep snow traverse with real consequence if you slip.
Afternoon lightning is a serious hazard above treeline. If clouds start building by midday, you need to be heading down, not up. The exposed ridge near the chalet is the last place you want to be in a storm.
Trail Details
Pro Tips
Start by 7 a.m. to beat the afternoon thunderstorms that roll in like clockwork from mid-July through August — and to snag parking at the Lake McDonald Lodge trailhead, which fills by 9 on summer weekends.
Carry at least three liters of water. There are reliable creek crossings in the first few miles, but the upper half above the junction with the Sperry Glacier trail is bone-dry and fully exposed.
If you're making this a day hike, push the extra 1.5 miles past the chalet to the Sperry Glacier overlook — it adds maybe an hour but gives you one of the most dramatic views in the entire park, and far fewer people make it that far.
