Brown County Portion
The 83 mile Mountain-Bay trail spans Brown, Shawano and Marathon counties. Its name is derived from Rib Mountain in Marathon County and Green Bay in Brown County. The trail is built on an abandoned railroad path and has a crushed stone surface.
The Brown County portion of the trail runs from the Village of Howard to the Village of Pulaski and is approximately 12 miles in length. Starting from the trailhead in Howard, the trail passes through a mix of woods, newly developed housing and farmland. The trail features numerous small bridges and a few road overpasses. Pulaski is a particularly trail-friendly area with several business catering to trail users including the Trail's End Bar and Grill, Mountain-Bay Plaza and the Trailside Convenience Store.
Care should be taken to avoid getting too close to the sloping trail shoulders due to occasional steep drop-offs.
