The 62-mile bike trail follows the former Chicago, Aurora and Elgin commuter train line. Abandoned in 1961, it was converted to the Prairie Path in 1963. The trail starts in Forest Park, but it's easier to pick it up in Elmhurst off Spring Road. Then ride it west to Wheaton. There are also branches to Elgin and Aurora. The most popular starting points are in Elmhurst, Wheaton (the trailhead), and Warrenville (by the library). Maps are available online.
