Welcome to the web site for the Mountain-Bay Trail, stretching 83 miles across north-central Wisconsin. Named for two geological features it connects – Rib Mountain in Marathon County and Green Bay in Brown County – the trail is built on the former Chicago and Northwestern right-of-way.
The Mountain-Bay Trail offers year-round recreation to both the casual and the outdoor enthusiasts. Bikers, hikers and snowmobilers are welcome. Adjacent to the trail are the services and amenities to make your outing an enjoyable one. Please pay attention! Trail Users must note that Usage Rules and Fees vary from county to county, and are advised to consult the Trail Descriptions on this site for specific information.
NOTE: SEE RESPECTIVE COUNTY PAGES FOR INDIVIDUAL MAPS AND DISTANCES
The Mountain-Bay Trail was developed by the Wisconsin Department of Natural Resources and parks departments of Marathon, Shawano and Brown County, and is currently maintained through the generous contributions and volunteer efforts of the Friends of the Mountain-Bay Trail of the three counties through which the trail passes: Marathon, Shawano and Brown.
Visitors to this site are asked to consider joining the Friends or making a contribution to their efforts. Please check out the Friends page on this site.
