Going-to-the-Sun Road West Side Backcountry Loop
Glacier's backcountry without the tourist traffic.
While tourists crawl up Going-to-the-Sun Road in rental cars, this rugged forest service network threads through the same territory via forgotten logging roads and mine access routes. The loop starts near Apgar and climbs through dense cedar and hemlock stands on increasingly technical terrain, with creek crossings and loose shale sections that’ll test your line choice. Key waypoint is the abandoned Belton Hills mining district where you’ll find rusted equipment scattered among towering trees.
Moderate to difficult depending on recent weather — spring runoff makes creek crossings sketchy, and fallen timber regularly blocks passages. Stock 4WD with good ground clearance handles it, but recovery gear’s smart for the boulder sections near Fish Creek. Best run July through September when roads are typically clear. No permits needed on forest service sections. What you get is Glacier’s backcountry without the crowds, plus some of the best dispersed camping spots in northwest Montana.

Frequently asked questions
Can a stock 4Runner or Tacoma handle this loop without modifications?
Yes — a stock 4WD high-clearance vehicle is the minimum and will get through under normal summer conditions. Lifted rigs will have more margin on the rougher sections, but factory skid plates and all-terrain tires go a long way here.
When does this loop actually open up, and is snow a real concern?
July through September is the reliable window. Snow lingers on shaded sections of these forest service roads into late June, and early October storms can close things fast. Check with Flathead National Forest before you go if you're pushing either end of the season.
Do you need any permits to run this loop or camp in the area?
No permit is required to drive the Flathead National Forest roads on this loop. Dispersed camping is allowed under standard National Forest rules — 14-day stay limit, 200 feet from water sources, pack out everything.
What's the hardest section of the trail and what makes it technical?
The roughest stretch involves loose rock, embedded ledges, and narrow shelf road with limited turnout options — expect slow going and some scraping if you're running stock clearance. It's moderate overall, but one or two spots will demand careful line choice, especially after rain when the dirt surface gets greasy.
Are the water crossings actual obstacles, and is there any reliable water for camp?
The crossings are typically low-volume and manageable mid-summer, but snowmelt runoff in July can push water levels higher — scout before you commit. There's surface water available along the route, so a filter or purification tablets mean you don't need to haul water for the full trip.
