Wisconsin Highway 101
WIS 101 begins at a junction with US 8 in Armstrong Creek in eastern Forest County. The highway heads north through the Town of Armstrong Creek, intersecting County Highway F near three lakes. From here the route crosses into Florence County, where it meets County Highway C west of the community of Fence. It continues northward through the forested Town of Fence, crossing the Popple River near a wayside. Past the river, the highway enters the Town of Fern. After running through the community of Fern, the route turns to the east near Price Lake. It turns northward again to pass through a forested area with many lakes, intersecting County Highway D in this area. After passing a county park by Keyes Lake, WIS 101 intersects WIS 70 in the Town of Commonwealth, and the two highways head eastward concurrently. The routes turn northeast into the Town of Florence, where they both terminate at US 2 and US 141 in western Florence.
