Circling Mackinac Island Professional Review and Guide
"With automobiles prohibited, Mackinac Island, in the Straits of Mackinac, is a bicyclist's dream. Bikers ride alongside horse-drawn carriages and hikers, on miles and miles of paved roads and paths that circle and crisscross the 3-mile-long island. The island's name comes from a shortened version of the Indian word Michilimackinac, or "large turtle," a reference to the shape of the island.
This ride, filled with military history and incredible vistas, features 8.1 miles of mostly flat land, along both woods and coastline, while traveling the island's perimeter. Things to see: Mackinac Bridge, Fort Mackinac, Arch Rock, British Landing Nature Center."
