Michigan Explorer's collection of trails & parks around the state.
Manistique, Schoolcraft County
Michigan's largest spring: 10,000+ gallons a minute, 45 degrees, and clear enough to count trout from a free hand-cranked raft near Manistique.
The raft is free, but a Michigan Recreation Passport is required for vehicle entry. Out-of-state vehicles: $12 daily or $42 annual (2026). Michigan-registered vehicles can only buy the annual pass, usually at license plate renewal — no daily option for residents
