Made possible by the cooperation and coordination of the U.S Forest Service, Forest County ATV clubs, townships, and their citizens, Forest County has more than 300 miles of ATV routes and 47 miles of state-funded ATV trails. Two state trails—the Nicolet State Trail and the Wolf River State Trail—provide ATV/UTVers with abundant recreational opportunities. Both trails are abandoned railroad corridors that have been surfaced with gravel. The Nicolet State Trail meanders through the Nicolet National Forest and the Wolf River State Trail runs adjacent to the forest, with a segment (between Highway 64 and Lily) running near the Wolf River, opportunities for nearby camping, hunting, fishing, hiking, mountain biking, and cross-country skiing are plentiful. (No hunting or trapping is permitted on the trails, however.)

Nicolet State Trail

The Nicolet State Trail passes through eastern Forest county communities of Carter, Wabeno, Blackwell, Laona, Cavour, and Newald. The Forest County segment of the trail is 32 miles long; it connects to Oconto County to the south and Florence County to the north for a total length of 90 miles. Although it is open for a variety of uses (including walking, mountain biking, horseback riding, and cross-country skiing), this shared-use trail is most popular for ATV/UTVing and snowmobiling. In the town of Laona, the trail is near the intersection of U.S. Highway 8 and State Highway 32. Just south of the Forest–Florence county line, the trail crosses the Popple River. Two parking areas are available: in Wabeno, between the town park and the Logging Museum, and off County Highway G, about 1 mile west of U.S. Highway 8.

Wolf River State Trail

The Wolf River State Trail is open from White Lake in Langlade County to Crandon in Forest County (33 miles). An additional 4 miles are being developed south of White Lake, to the Menomonee–Langlade county line. The Forest County segment of the Wolf River State Trail is 15 miles long and passes through central and southern part of Forest County. Both trails are abandoned railroad corridors that have been surfaced with gravel. They are open all year for ATV, UTV, dual-sport motorcycles, and snowmobiles. The Wolf River State Trail is open from White Lake in Langlade County to Crandon in Forest County, totaling 33 miles.
