Mackinac Island to Winterset: A Scenic Midwest Road Trip Guide

Mackinac Island, Michigan, sits in Lake Huron, famously car-free since 1898, while Winterset, Iowa, boasts the world's largest concentration of covered bridges. The 550-mile drive between them, primarily via I-75, I-94, and I-80, takes roughly 9 hours without stops. This guide dives deep into the best stops, hidden gems, and logistical advice for a memorable road trip.

One little-known fact: the route crosses the Mackinac Bridge, a 5-mile suspension bridge that connects Michigan's peninsulas. It's a toll bridge ($4.00 for cars) and often windy—speed limits drop to 20 mph for high-profile vehicles.
