A feature of Montevallo’s Orr Park is a walking trail with more than 30 cedar tree carvings. The railroad museum in Calera features operating trains, restored depots, and a collection of locomotives and cabooses. Shelby County is also home Oak Mountain State Park, Alabama’s largest state park, and the University of Montevallo.
