The premier resource for Michigan waterfalls is GoWaterfalling, and their entry for Horseshoe Falls in Munising says (in part):
Horseshoe Falls is a scenic, privately owned waterfall in Munising. There is an admission fee to visit the falls. It is spring fed, so it may be flowing when the other five falls in the area are not.
Horseshoe Falls is located in the middle of Munising, just a few blocks away from M-28 … It plunges about 20 feet, and then tumbles down a long series of cascades for another 20 feet or more. The waterfall is spring fed, so it may be running when the other nearby falls thin out in the summer months.
In addition to the falls there is a trout pond, where you can feed the fish.
