Nemadji State Forest Quarry Loop
Technical sandstone quarry climbs through industrial ruins
The Nemadji State Forest conceals the scarred remains of early 1900s sandstone quarries, where massive extraction pits now form natural rock gardens connected by technical four-wheel tracks. The main challenge hits at Quarry Hill—a steep, loose sandstone climb that requires momentum and precise wheel placement to avoid the washouts carved by decades of spring runoff.
This difficult route demands experienced drivers with lockers and recovery gear—the sandstone becomes treacherously slick when wet, and several climbs have no bailout options. Stick to dry conditions between June and October. The payoff is solitude in country most Minnesotans never see, plus unique geology that tells the story of the state’s industrial past. Dispersed camping available near the old quarry supervisor’s cabin ruins, but pack everything in and out—this isn’t maintained recreation land.

Frequently asked questions
Can a stock 4Runner make it through the quarry climbs?
No, you need a modified 4WD with lockers minimum. The sandstone ledges and quarry walls require serious articulation and traction control that stock vehicles can't handle.
Is this trail accessible in winter or spring?
Best season is June through October. Winter snow makes the technical rock sections extremely dangerous, and spring mud can make approach roads impassable.
Do I need permits to drive through the state forest quarry areas?
No permits required, but you must stay on designated trails. The Minnesota DNR manages this area and prohibits off-trail travel to protect the fragile quarry environment.
What's the gnarliest obstacle I'll face on this trail?
The main quarry wall climb is a near-vertical sandstone ledge that demands perfect line choice and spotters. Most people winch it rather than drive it.
Can I camp at the old quarry sites?
Yes, dispersed camping is allowed throughout the state forest, but avoid camping directly in the quarry pits for safety. Cell service is spotty so download offline maps before heading out.
