Nicolet National Forest Copper Falls Loop
Mining history meets northern Wisconsin wilderness
This 18-mile forest road loop cuts through some of Nicolet’s densest timber, where loggers once hauled white pine giants on ice roads. The trail kicks off near Mole Lake, winding past abandoned copper prospect holes and crossing Thunder Creek three times before hitting the challenging section around mile 12 — a rocky climb through maple and birch stands that’ll test your diff lock. Old mining equipment rusts beside the trail, testament to the 1920s copper boom that never quite panned out.
Moderate difficulty with a few technical spots requiring 4WD and skid plates. Stock clearance handles most of it, but the creek crossings can get interesting during spring melt or heavy rains. Best tackled May through October when the water’s manageable. No permits needed, but respect the forest closure signs. Multiple dispersed camping spots along Copper Creek, plus you’ll see more wildlife than people out here — black bears, deer, and if you’re lucky, a timber wolf crossing at dawn.

Frequently asked questions
Can a stock Jeep Wrangler handle the Copper Falls Loop?
Yes, a stock Wrangler with 4WD will handle this trail fine. The moderate rating comes from a few rocky sections and stream crossings, but nothing requiring aftermarket modifications.
Is the trail accessible in early spring or late fall?
Best to stick to May through October. Spring mud season makes the forest roads impassable, and snow typically blocks access from November through April.
Do I need permits to camp along the Copper Falls Loop?
No permits required for dispersed camping in Nicolet National Forest. Follow Leave No Trace principles and camp at least 100 feet from water sources.
What's the most challenging part of this trail?
The stream crossings can be tricky during high water periods, especially in spring runoff. Water depth varies seasonally but rarely exceeds 18 inches at normal levels.
How many water crossings should I expect on the loop?
You'll encounter 4-5 stream crossings throughout the 18-mile loop. Most are shallow rocky creek beds, but scout them first if you're unsure about depth or current.
