Nicolet National Forest Blackjack Springs Wilderness Access Road

The Blackjack Springs Wilderness Access Road follows Depression-era Civilian Conservation Corps routes deep into the Nicolet’s most primitive 5,904-acre wilderness. Starting from Blackjack Lake boat landing, the route climbs through sugar maple stands and crosses multiple spring-fed creeks before reaching the wilderness boundary at mile 6. The technical challenge comes at Hemlock Creek crossing, where limestone ledges create natural steps requiring precise wheel placement and a spotter.

This difficult trail requires experienced 4WD drivers with skid plates and recovery gear—the creek crossings can trap inexperienced wheelers, and cell service is nonexistent. Best attempted June through early October when water levels drop but before fall rains turn the clay sections into axle-deep slop. No permits for the access road, but wilderness entry requires registration. Dispersed camping allowed outside wilderness boundaries. You’ll find Wisconsin’s closest thing to true backcountry solitude, plus some of the state’s best brook trout fishing in waters few anglers reach.
