Sebewaing This is where the scenic tour ends...however, there is still much to enjoy if you get off M-25 or just by staying on the highway. Best places to stop on this route? Grindstone City – it had the first major business in the Michigan Thumb and is now considered a 'ghost town', even though they have tourist attractions. Pointe Aux Barques Lighthouse – one of Michigan's Most Haunted locations, what would this trip be without seeking out something spooky? Turnip Rock– one of Michigan's coolest natural curiosities. Port Crescent– a ghost town with nothing left but a chimney and one of the coolest old graveyards in the state.
