>>2487058Ludington to Mackinac is peak MI.
UP if you hate all evidence of humans and are willing to trade that for flatness.
Manistee river trail is most popular overnight hike
Sleeping Bear's various trails are most scenic (do August)
There's tons of state forests, but you're usually within a mile or two of someone's property or other campers, it's not super remote but as soon as you get away from campgrounds it's pretty isolated.
The best thing about MI is its lakes and waterways. Get yourself a boat/kayak/canoe and have fun.
Enjoy the next 8 months...
