The Friendship State Trail connects Brillion and Forest Junction along Hwy 10 in Calumet County. This trail opened in 2003 and was developed in partnership with the WI DNR, Calumet County, and the Friends of the Friendship Trail.
This 4-mile trail passes through woodland, scenic farmland, and portions of the City of Brillion. The trail begins at the intersection of Center Road and South Glenview Avenue in the City of Brillion. The trail connects with the Fox River Trail in Forest Junction near the intersection of Main Street and Milwaukee Street.
The trail can be used for hiking, biking, and horseback riding. No motorized vehicles are permitted during the hiking, biking, and horseback riding season. In winter this trail is part of the Calumet County snowmobile trail system.
