Big Thunder Peak

Big Thunder Peak is a 1,752-foot summit in Minnesota. The Big Thunder Peak Trail covers 7.8 miles round trip (out-and-back) with about 118 feet of elevation gain — a gradual walk with modest climbing.

Getting There

The trailhead is at 47.10761, -93.61839 (tap for driving directions). It's roughly 150 miles north of Minneapolis, Minnesota. 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 Easy rating comes from the National Park Service difficulty formula, which weighs total distance against elevation gain. Most hikers should budget about 2.5 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. Trail data is sourced from OpenStreetMap contributors (ODbL).
