There is a great cycle- friendly campground near Traverse City, Michigan called Cycle Moore. Might be a good place to camp for a few days as you take day trips in the area.
M-22 is a great ride along the Lake Michigan shore as is M-23 along Lake Huron. Plan also to ride the Tunnel of Trees (M-119) too. If you are into authentic Polish food, stop at Legs Inn, which is a short ride south of the Bridge.
