Nicolet National Forest Anvil Lake Technical Loop

The Anvil Lake Technical Loop earned its reputation the hard way, threading through house-sized granite boulders left by retreating glaciers 10,000 years ago. Starting near Anvil Lake Campground, the route immediately climbs through what locals call the ‘Rock Garden’ — a mile-long obstacle course of granite slabs and tight squeezes that’ll test your spotter’s patience and your truck’s armor. The trail follows old copper mining roads from the 1880s, passing the collapsed shaft of the Anvil Mine before dropping into a technical descent known as ‘Pinball Alley’ where trees grow uncomfortably close to the trail.

This is expert-level wheeling that demands rock sliders, skid plates, and a solid understanding of line choice. Summer conditions are best, though even then expect body damage if you’re not careful. The loop connects to Forest Road 2178 for an easier exit if things get too spicy. No permits required, but the Anvil Lake Campground makes a good base camp for multiple attempts. Eagle River is 15 minutes away for repairs and cold beer. The granite challenges here rival anything in the Southwest, just with more trees trying to grab your mirrors.
