The horseback riding/hiking trail begins at Lake Michigan in Empire on the west side of the state and ends at Lake Huron near Oscoda on the eastern side. It's the longest continuous trail in the Lower Peninsula. Around Traverse City, the trail cuts through Lake Dubonnet, Muncie Lakes, the Sand Lakes Quiet Area and then heads north of Kalkaska before continuing eastward. There's also a southern spur that goes down to Cadillac, and a northern spur that ends east of Indian River. And the North Country Trail joins the shore-to-shore trail for a short distance north of Kalkaska. The trail passes under Interstate 75 north of Grayling and continues eastward to follow the scenic AuSable river on toward its destination, AuSable just south of Oscoda. The trail features campgrounds, complete with privies and wells, at approximately 18 to 25 mile intervals. Most of the camps overlook lakes or rivers. No bicycles are allowed on this trail.
