One of Michigan's hidden jewels, the 12.5-mile Wadhams to Avoca Trail travels on a former CSX Railway line that was purchased by the St. Clair County Parks and Recreation Commission in 1999 and opened for recreational use in 2003. The original rail line, completed in 1882, connected Port Huron with Saginaw and 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. Look for the trailhead on your left at the Wadhams to Avoca Trail crossing signal. Restrooms, food and drinks are available at businesses next to the trailhead. The first 5 miles of the southern section of trail are paved with asphalt, passing through a mostly wooded terrain with long tunnels of trees and seasonal blooms of wildflowers.
At McLain Road, the trail surface changes to finely screened and compacted limestone. The hard-packed surface is well maintained and suitable for most bikes. This northern section of trail travels through farm country and is also open to horseback riding.
The highlight of the Wadhams To Avoca Trail is the Mill Creek Trestle, or "High Bridge," located 1.5 miles south of Avoca. This 640-foot long, 60-foot high steel trestle bridge offers commanding views of the Mill Creek Valley; a great place to stop, relax and soak up the scenery. The trail ends in the quaint village of Avoca where you will find a convenience store, tavern, cafe and the Avoca Trailhead.
