Glacier Rim Drive (Going-to-the-Sun Road Extension)
Hidden Glacier backcountry beyond the crowds
Beyond the tourist traffic of Going-to-the-Sun Road lies this lesser-known extension that climbs from Logan Pass toward Hidden Lake Overlook via old park service maintenance roads. The route parallels the Continental Divide through subalpine meadows before dropping into the Sperry Creek drainage. At mile 8, you’ll hit the remains of the old Sperry Chalet supply road—now just two granite ruts through avalanche debris and meltwater channels.
Moderate difficulty for the gravel sections, but becomes technical where creek crossings meet loose talus slopes. Stock 4WD works fine with good ground clearance, though the final 4 miles require careful line choice through boulder fields. Open July through September only—snow blocks access well into summer. No services whatsoever, and cell coverage dies at Logan Pass. Worth it for solitude in one of the most scenic corners of Glacier, with dispersed camping possible at Sperry Creek junction.

Frequently asked questions
Can a stock Jeep Wrangler handle Glacier Rim Drive?
Yes, but barely. You'll need high clearance and 4WD for the rocky sections and water crossings. Stock ground clearance is the minimum — more is better.
Is Glacier Rim Drive open in winter?
No, the trail is only accessible July through September due to snow at 7200 feet elevation. Even early July can have snow patches blocking the upper sections.
Do I need permits for Glacier Rim Drive?
Yes, you need a Glacier National Park entrance pass. Backcountry camping requires additional permits from the park service, which book up months in advance.
What's the hardest part of this trail?
The water crossings about 8 miles in can be sketchy during snowmelt season. Rocky ledges near the rim require careful line choice and spotting.
Is there cell service on Glacier Rim Drive?
Zero cell service once you leave the main park road. Bring a satellite communicator if you're traveling solo or camping overnight.
