From downtown Green Bay, the Fox River State Trail winds along the beautiful Fox River before extending for 25 miles along a former rail corridor. The Fox River corridor has a rich history, beginning with the Native Americans who used footpaths to travel between their villages located along the river. The early French explorers, missionaries and traders built their posts and missions along these trails.From the north trailhead in Green Bay, about 11 miles of the trail is asphalt-paved to Lasee Road. From Lasee Road south into Calumet County, the trail is surfaced with limestone screenings. Along the way, the trail passes by numerous overlooks along the Fox River, many local parks and the Brown County Historical Society. A "Health Trail" along a portion of the Fox River Trail in Allouez provides trail users with an outdoor fitness challenge course. 

An Annual State Trail Pass or a Daily Pass is required for bicyclists, rollerbladers, and horseback riders over 16 years old. There is no fee for walkers.
