The International Ironworker Festival is an annual event held each summer in Mackinaw City. It attracts Ironworkers from across the United States and Canada to compete in friendly competition. It is open to the General Public, although only Ironworkers and Retirees can compete in the skilled events. These events include knot tying, rod tying, rivet toss, spud throw, column climb (Field Event), and the World Championship Column Climb. Come join us for a fun filled weekend!
