South of Shingleton, the Haywire Trail is a 33 mile snowmobile route along an old railroad grade. The route begins on M-94 south of Shingleton and ends at the Water Intake Plant in Manistique.
Northern Trailhead: Located just south of Shingleton, a sign marks the northern trailhead on the east side of M-94. There is no parking at the trailhead, but spaces may be available at or near local businesses on M-28 in Shingleton, less than 1/3 mile north of the trailhead.
Southern Trailhead: The southern trailhead is located just north of Manistique off of M-94. Turn east on Riverview Road, following it to the parking area just beyond the Water Intake Plant.
Northern Trailhead to M-94 (first crossing) (1.3miles) After the corridor was purchased, part of it was reserved to maintain access to the active east/west rail line at Shingleton. This made it necessary to cut a 0.3 mile connector from the corridor to M-94 establish a trailhead. Angling toward the old rail grade, the first 0.3 miles has ruts and may be seasonally wet. Mountain bikers, be prepared to walk. An alternative for some would be to stay on M-94 (which has a 3-foot paved shoulder) for 1.3 mile and pick up the trail where it first crosses the highway.
M-94 crossing to Steuben (11.6 miles) Mountain bikers should be able to navigate the trail to Steuben even though at times it is sandy or periodically covered by water due to beaver activity. This segment of trail crosses one road, contains eleven bridges, and briefly borders the Big Island Lake Wilderness.
Steuben to Trail via Bypass (2.5 miles) the section of trail south of Steuben is occasionally washed away by beavers and is then temporarily closed. The best alternate route is to take the Thunder lake Road (County Rd 437) east 1.5 miles to M-94 and then south one mile to where the trail again crosses the highway. Not only will this bypass the temporary beaver damage, but it gets you past the deep sand found along this section of the trail.
M-94 (2nd crossing) to M94 (3rd crossing) (37 miles) Once back on the grade, the trail becomes a hard-packed two-track that passes through a recently logged area. About 1.5 miles for the second M-94 crossing another trail veers off to the right, leading to Indian River Camp and Picnic Grounds one mile away.
M-94 (3rd crossing) to M-94 (4th crossing) (14 miles) About 4.4 miles beyond the third M-94 crossing is a large wet area with hunks of gravel fill. About 0.3 miles later, near the Hiawatha Station, a sandy stretch may give some trail users problems.
M-94 (4th crossing) to Southern Trailhead (6.3 miles) about 1.7 miles after the fourth M-94 crossing, a two-track service-drive intersects the trail. (If you head west 0.8 miles on this service-drive you will find a snowmobile parking area off M-94 that is 4.5 miles from Manistique.) Continuing along the trail past service-drive, it is only 4.6 miles to the Southern Trailhead. About 3.7 miles past the service-drive, a snowmobile trail takes a sharp left away from the corridor. Don't be tempted to take this.
Overall, Haywire Trail is the 35th most popular snowmobile trail of all 36 snowmobiling rides in Michigan.
