What to Expect

This is Glacier's great staircase — a relentless six-mile climb that gains more vertical than most ski resorts drop. You'll start in dense cedar-hemlock forest along Snyder Creek, cross a series of switchbacks through wildflower meadows that explode with beargrass and paintbrush in July, and eventually break above treeline into the kind of alpine scenery that makes you forget your legs are on fire. The trail is well-maintained but rocky in stretches, with a few exposed traverses that'll get your attention. The payoff is Sperry Chalet itself — a stone lodge perched on a cliff shelf at 6,600 feet, first built in 1913 and rebuilt after the 2017 fire. The views of Lake McDonald's valley and the surrounding peaks are earned in every sense of the word. This trail rewards strong hikers who want a legitimate mountain day without technical terrain.

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.

Pro Tips

Trail Tip

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.

Trail Tip

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.

Trail Tip

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.
