The Nahma Grade Trail is popular with snowmobilers; it's groomed in winter and links to other area snowmobile trails. The trail passes through a corridor of pine woods, open space and lowland sand flats. Much of the trail follows an abandoned logging railroad grade.
The southern trailhead is near the intersection of US 2 at Forest Road 13, and the Nahma Grade Trail roughly parallels FR 13, heading north toward the DeltaAlger county line. For maps, contact the Hiawatha National Forest.
