Biking Going to the Sun Road: What to Know Before You Ride

What Is Going-to-the-Sun Road?

Going-to-the-Sun Road is a 50-mile scenic highway that runs through the heart of Glacier National Park, drawing millions of visitors each year for its dramatic mountain views, alpine meadows, and iconic landscapes. Widely considered one of the most scenic drives in the U.S., the road showcases Glacier’s towering peaks and glacial valleys from start to finish.

Along the route, you’ll pass notable landmarks and gain elevation as you climb toward Logan Pass:

• Avalanche Trailhead / Trail of the Cedars – 3,300’ (Mile 1)
• The Loop – 4,400’ (Mile 8)
• Bird Woman Falls – Mile 11
• Weeping Wall – Mile 13
• Triple Arches – 6,180’ (Mile 15)
• Logan Pass – 6,646’ (Mile 16)

While many visitors experience the road by car, biking Going-to-the-Sun Road offers a completely different perspective. You’ll feel every climb, breathe in the crisp mountain air, and take in the scenery at your own pace—especially during quiet spring mornings or car-free periods when the experience is even more immersive.

Biking Going-to-the-Sun Road: Is It Right for You?

This ride is accessible to a wide range of cyclists—but it’s important to be realistic.
