Wagner Falls Posted on December 22, 2016December 22, 2016 by kwschnei Wagner Falls is a gorgeous set of waterfalls located a short distance from the MI-28/MI-94 intersection south of Munising. Often overlooked by travelers it is a great spot to get out and stretch your legs at the 23-acre state park upon which it is located. Wagner Falls flows over dolomite and empties into the Anna River, which in turn flows into Lake Superior.
