Mackinac County Forest Road 3151 Black River Technical Loop
Remote UP timber country technical challenge
Forest Road 3151 cuts through the forgotten timber country of Mackinac County’s eastern wilderness, where abandoned logging camps once fed the Great Lakes lumber boom. This remote two-track winds through dense hardwood forest along the Black River drainage, crossing multiple seasonal creeks and navigating steep grades that still bear the scars of turn-of-the-century log skidding operations. The route features several technical rock gardens near Mile Marker 4.2 and a notorious mud hole at Beaver Creek Crossing that’s claimed more than one overconfident driver.
This is legitimate backcountry wheeling requiring high-clearance 4WD with skid plates and recovery gear. Deep ruts, fallen timber, and seasonal washouts keep most weekend warriors away. Best tackled May through October when water levels drop and mosquitoes ease up slightly. No permits needed, but bring extra fuel — nearest gas is 40 miles back in Newberry. The reward is pristine wilderness camping along Black River and some of the finest brook trout water in the Upper Peninsula.

Frequently asked questions
Can a stock Jeep Wrangler or 4Runner handle this trail, or do I need lockers?
A stock high-clearance 4WD with skid plates is the minimum — think bone stock Wrangler or 4Runner on all-terrain tires. Lockers aren't strictly required but will save you on the muddier creek crossing approaches; without them you'll need solid momentum management and may need to winch if conditions are soft.
What time of year is this trail actually passable, and is spring runoff a problem?
Best season is May through October, but early May can be brutal — snowmelt turns the logging grades into grease and the creek crossings run high. Wait until late May or June for more predictable conditions, and after heavy rain any time of year expect the clay-heavy dirt surface to get slick fast.
Do I need a permit or any fees to run this trail and camp along it?
No permit or fee is required to drive or camp here — Mackinac County Forest Commission manages the land and dispersed camping is allowed. There's no registration system; just follow Leave No Trace and don't block the forest road.
What's the hardest section of this trail and what specifically makes it technical?
The steep logging grades combined with off-camber clay surface are the real challenge — when wet, they're greasy enough to push even a capable rig sideways. The creek crossings add technical variety but the grades are where most rigs get into trouble; expect rutted two-track with tight tree lines that punish wide vehicles.
There's zero cell service out here — how far is the nearest fuel and should I be carrying extra water?
Newberry is your last fuel stop and sits roughly 20-30 miles from the trailhead, so top off before you head in and carry extra if your range is tight. The creek crossings provide surface water but treat everything before drinking; bring your own supply for camp to avoid any issues with upstream logging activity contaminating the water.
