Mackinac Island to Traverse City Road Trip Guide

This 185-mile journey from Mackinac Island to Traverse City crosses the iconic Mackinac Bridge—a 5-mile suspension bridge linking Michigan's Upper and Lower Peninsulas. The bridge's steel deck sits 200 feet above the Straits of Mackinac, a rare place where Lake Huron and Lake Michigan meet.

You'll follow US-31 and M-119, passing through Petoskey, Harbor Springs, and Charlevoix. The drive takes roughly 3.5 hours without stops, but the real magic lies in the 45 miles of M-119's Tunnel of Trees, a canopy-lined road hugging the Lake Michigan shoreline.
