The Oak Leaf Trail is a multi-use trail system with over 125 miles of trail for cycling, roller blading, walking and running around Milwaukee County. Nearly a quarter of the trail hugs the beautiful shores of Lake Michigan. The trail is mostly smooth asphalt, with dozens of easily accessed connections that take you just about anywhere in the Milwaukee metro area. Portions of the trail are on Milwaukee County Parkways, shared with traffic, and some sections use municipal streets.
