Mount Gordon Lyon

Mount Gordon Lyon is a 4,127-foot summit in Alaska. The Mount Gordon Lyon Trail covers 2.0 miles (loop) with about 1,201 feet of elevation gain — a steady climb. It's rated Moderate overall.

The Route

The grade is back-loaded: the first half of the route climbs gently, and most of the elevation gain comes in the second half. The steepest stretch arrives around mile 1.54, gaining roughly 3,000 feet per mile — expect a slow, deliberate pace through here.

Getting There

The trailhead is at 61.24882, -149.50615 (tap for driving directions). Arrive early on weekends — trailhead lots at popular peaks fill quickly, and cell service is often unreliable once you leave the highway.

When to Go

Late May through October is the main season. Snow and ice linger into spring and return early in fall at this latitude and elevation; in winter this becomes a different, more serious undertaking requiring traction devices and warm layers.

Know Before You Go

The Moderate rating comes from the National Park Service difficulty formula, which weighs total distance against elevation gain. Most hikers should budget about 1.5 hours of moving time; add margin for breaks, photos and the descent. Download the GPX track from this page before you go — cell coverage is unreliable in the mountains and a saved route works offline in any GPS app. Conditions change: verify current access, closures and weather with the official land manager before you go.
