Superior National Forest Temperance River Backcountry Road
Old-growth wilderness penetration
Forest Road 336 traces the Temperance River inland from its famous gorge at Lake Superior, climbing through some of the most pristine old-growth forest remaining in Minnesota. This challenging 22-mile route starts just north of Schroeder and immediately plunges into dense canopy where 400-year-old white pines tower overhead. The road follows the river’s course through a series of granite-walled pools and cascades, crossing the main stem twice on narrow timber bridges that require precise wheel placement. Carlton Peak’s granite dome looms to the south as you navigate washouts and fallen timber.
This is serious backcountry requiring high-clearance 4WD and recovery gear. Spring snowmelt and fall rains turn the clay sections into axle-deep quagmires. Late summer offers the best conditions, but expect slow going over exposed bedrock and through tight timber stands. Excellent dispersed camping exists along the river, though you’ll need to pack everything in. No cell service once you leave the highway, and the road officially ends at the Boundary Waters Canoe Area wilderness boundary.

Frequently asked questions
Can a stock Wrangler handle this trail or do I need aftermarket modifications?
A stock Wrangler with good tires can complete this trail, but you'll work for it. The water crossings and rocky sections will test your clearance and approach angles, so skid plates are highly recommended.
Is the trail accessible in early June or do I need to wait until July?
Wait until July unless you enjoy mud bogs and getting stuck. Spring runoff keeps the trail soft and the water crossings dangerously high through June.
Do I need a permit to camp along this forest service road?
No permits required for dispersed camping in Superior National Forest. Follow Leave No Trace principles and camp at least 150 feet from water sources.
What's the worst section of the trail I should be prepared for?
The water crossings around mile 8-12 are the technical crux - rocky creek beds with potential for high water and slippery granite. Take your time and walk them first.
How many days of water should I bring since there's no cell service?
Bring enough water for your entire trip - the Temperance River looks clean but filtering takes time and you're in true backcountry. Plan for 1 gallon per person per day minimum.
