Going-to-the-Sun Road Alpine Loop

They said it couldn’t be built. This 50-mile mountain road climbs from cedar forests to alpine tundra, hugging cliff faces so narrow that RVs over 21 feet are banned. Carved into Glacier National Park’s Continental Divide between 1921 and 1932, the route reaches 6,646 feet at Logan Pass, where mountain goats wander parking lots and Hidden Lake reflects glacier-carved peaks. The western approach from Apgar follows McDonald Creek through old-growth forest, while the eastern climb from St. Mary delivers prairie-to-peak drama in 12 switchbacking miles.

This is scenic driving, not technical 4WD, but don’t underestimate the pucker factor. The road is barely two lanes with stone retaining walls and thousand-foot drops. Plowed fully only July through October due to snowpack that can reach 80 feet deep. No permit required but arrive early—parking at Logan Pass fills by 8 AM in summer. Vehicle restrictions include 21-foot length and 8-foot width limits. What you get is America’s most spectacular mountain drive, period.
