Ride the Fringe: The M-185 Perimeter Tour (CLICK FOR MAP)
The M-185 Perimeter Tour is an 8 mile state highway that loops around Mackinac Island’s shoreline. From start to finish, the flat, smooth asphalt road places you right between dramatic forestry and the rocky shores of Lake Michigan and Lake Huron with majestic views of their deep blue waters.
You’ll enjoy pristine air and the tranquility of the island at your own pace, as you ride past incredible limestone formations, trickling island streams, and numerous historic points of interest.
Suitable for all ages and riding abilities, the perimeter tour can be completed at a leisurely pace within 1-1/2 hours, including time for photo opportunities and restroom breaks along the way.

Build a Rock Cairn while on your M-185 Perimeter Tour
Rock cairns are small mounds of stones and pebbles built to mark biking and hiking trails, as a memorial to having been somewhere, or as a simple art form. Cairns can be found all over the world, from alpine regions, to barren desert and tundra, as well as coastlines.

It is traditional for each person passing by a cairn to add a stone, as a small bit of maintenance to counteract the effects of wind and weather. Often the habit is to only add to the top, and to use a smaller stone than the previous top stone, resulting in a precarious stack of tiny pebbles.
While on your M-185 perimeter tour, express yourself by building your own rock cairn. Take a photo of your cairn and share it with us. We’ll post the coolest looking cairns on this website and every month send the best design a free RIDE THE FRINGE T-shirt.
