Gunsight Pass to Ptarmigan Tunnel — Many Glacier Remote Valley Drive via Swiftcurrent Ridge
Grizzly country and glaciers at road's end.
The Many Glacier Road is one of the most rewarding and genuinely wild road-access drives in the lower 48 — full stop. You enter off US-89 north of St. Mary, climb into the Swiftcurrent Valley through dense aspen and cottonwood bottom, and suddenly the full wall of the Continental Divide rises ahead of you: Grinnell Point, Mount Gould, and the Salamander Glacier hanging above Josephine Lake. The road itself is paved but narrow, with no guardrails in key sections, frequent grizzly bear crossings, and the kind of traffic congestion in July that turns a 12-mile road into a two-hour ordeal. Hit it at dawn or at dusk to dodge the crowds and catch the alpenglow on the Grinnell Glacier headwall.
Vehicle requirements are minimal — any passenger car can make it on a good day — but the real gating factor is the park’s vehicle reservation system, which is required May through September for timed entry. Without a reservation, you’re turned away at the St. Mary entrance. Book early; they sell out months in advance. Fuel up in Browning or St. Mary — there is nothing inside the park. Cell service is spotty at best. Camping is available at Many Glacier Campground (reservable through Recreation.gov) and is often booked solid by February. This valley earns its reputation every single time.

Frequently asked questions
Do I need a high-clearance 4x4 to drive into Many Glacier?
No. The road into Many Glacier is a maintained dirt and gravel park road — any passenger car or standard SUV can handle it. High clearance and 4WD are not required.
When does the Many Glacier road open and close for the season?
Typically accessible July through September, depending on snowpack. The road can stay closed into early July some years — check NPS road status before you go, especially early and late season.
Do I need a permit or reservation to drive to Many Glacier?
Yes. During peak season Glacier National Park requires a timed-entry vehicle reservation for the Many Glacier corridor. Book in advance at recreation.gov — these sell out fast.
What's the hardest part of this drive and what should I actually expect?
There's nothing technically difficult here — it's a scenic valley drive, not a rock crawl. The challenge is the narrow road in spots with no guardrails, significant drop-offs, and heavy wildlife activity including grizzlies close to the road.
Is there any cell service in the Many Glacier valley, and where's the nearest gas?
Cell service is spotty to nonexistent once you're in the valley — don't count on it for navigation or emergencies. Fuel up in Babb or St. Mary before heading in; there's no gas inside the park at Many Glacier.
