The 12.5-mile Wadhams to Avoca Trail was built on a former CSX Railway line that was purchased by St. Clair County Parks in 1999 and opened for recreational use in 2003. The original rail line, built in 1882, was called the Port Huron & Northwestern Railroad. The entire trail is smooth and flat, and a pleasant day ride for people of all abilities. The Wadhams Trailhead is easy to find, just north of Interstate 69 at the Wadhams Road exit. The 5-mile southern section is paved with asphalt, passing through mostly wooded terrain with long tunnels of trees. At McLain Road, the trail surface changes to finely screened and compacted limestone as it passes through quintessential farm country. Horseback riding is permitted and popular on this section of trail. The Mill Creek Trestle or “High Bridge” is located 1.5 miles south of Avoca.

The centerpiece of the trail is the 640-foot long Mill Creek Trestle. Built in the late 1800’s, the 60-foot high trestle has been decked and railed to provide safe access for walkers and bicyclists.
