TRAIL REPORT
March 28, 2026
Munising’s trails are holding up surprisingly well for the final weekend of the season.
Munising’s trails are holding up surprisingly well for the final weekend of the season.
Overall Conditions:
The base remains solid across most of the eastern Upper Peninsula. Three groomers are currently active to keep the main routes smooth for the end-of-season rush.

Trail-by-Trail Breakdown:
- Trails 7 (North & South), 8 (East & West), and 419 (Wetmore/Munising) are all currently rated as Good. These are your best bets for consistent coverage.
- Trail 8 North toward Shingleton is mostly good, but keep an eye out for a known water hole on the path.
- Trail 418 (Au Train) has good snow, but there is significant standing water on the trail shoulders. Trail 417 is starting to get thin as you get closer to the Lake Superior shoreline heading toward Marquette.
- Trail 422 (Miners Castle) is the outlier—it hasn't seen a groomer lately and is reported as very rough.
Rider Alerts:
The Au Train River crossing on Trail 418 may have a temporary closure; if so, use Trails 7, 8, or 417 to bypass it.
