The multiuse Haywire Grade Trail stretches 32 miles and crosses the Upper Peninsula, south to north, from Intake Park in Manistique to Shingleton in Schoolcraft and Alger counties. The trail was Michigan’s first rail trail. The trail runs along the old Manistique and Lake Superior Railroad and has since been reclassified as a year-round, multiuse trail – the first in Michigan's Upper Peninsula.

The trail surface is a mix of sand, gravel and coarse limestone, designed for snowmobiles and ATVs, but suitable for fat-tire biking. Mile markers help you track your progress through this secluded second growth forest. You’ll find a small grocery store in the tiny hamlet of Steuben, the last vestige of the many logging camps or towns that vanished after the railroad was abandoned.

Converted into a recreation trail in 1970, the Haywire Grade Trail celebrated its 50th anniversary in 2020 with special events and commemorate rides for snowmobiles, equestrians, bicycles and ORVs.

The trail has been recognized as a Pure Michigan Designated Trail and designated as a heritage trail. The heritage trail project includes a series of 11 historical interpretive kiosks that explore the natural and cultural history of the area

Trailheads:

• A sign marks the northern trailhead on the east side of M-94 just south of Shingleton. There is no parking, but spaces are available east of the Tanglewood Restaurant and Antique Shop on M-28 in Shingleton less than a quarter mile north of the trail.
• The Manistique Trailhead is located on the banks of the Indian River at Intake Park in Manistique (on Intake Park Road).
• The Jack Pine Trailhead is located at Jack Pine Lodge on M-94 (about half way between Manistique and Shingleton).
