This section of the Tunnel Hill State Trail starts from the Tunnel Hill Road trailhead and goes to a turnaround point at Breeden Trestle. The hike travels through the tunnel for which the trail was named and provides lots of nice scenery. The trail does continue on in both directions for many more miles so adding mileage and exploring more of the area is a nice option. The hike can also be done as a one-way trip by shuttling vehicles if desired. The trail is multi-use so watch for bikers and joggers along the way.
