M209 is very short taking you from M109 to the "ghost town" of Glen Haven which is owned by the National Lake Shore/ Sleeping Bear Dunes Park. It is an interesting little place with a number of cool historic sites to check out.
M109 takes you from Glen Arbor to M22 just north of Empire. Along
the way are incredible views of the Sleeping Bear Dunes and Little Glen
Lake. M109 also has wide and biker friendly bike lanes for your safety.
