Unlike some nearby cities and villages, the City of Mequon has large areas of rural and undeveloped land without sidewalks for pedestrian traffic. However, the Ozaukee Interurban Trail for pedestrian and bicycle use runs north-south through the city and connects Mequon to the neighboring community of Cedarburg in the north and Brown Deer in the south, where the trail connects to Milwaukee County's Oak Leaf Trail. The Ozaukee Interurban Trail continues north to Oostburg in Sheboygan County. The trail was formerly an interurban passenger rail line that ran from Milwaukee to Sheboygan. The train was in operation from 1907 to 1948, when it fell into disuse following World War II. The old rail line was converted into the present recreational trail in the 1990s.
