About Mackinac Island

Mackinac Island prohibits automobiles, a time capsule where horse-drawn carriages and bicycles reign, where Victorian cottages cluster near the harbor, and fudge aroma permeates the streets. The island sits in the Straits of Mackinac between Lake Michigan and Huron, accessed by ferry from the mainland.

Mackinac Island is a small car-free island in Lake Huron where horse-drawn carriages and bicycles are the only ways to get around, and the grand Victorian-era Grand Hotel still serves afternoon tea on the world's longest porch. Fudge shops line the main street (the island is famous for it), limestone bluffs and the historic Fort Mackinac overlook the harbour, and a loop around the island's perimeter road offers constant lake views without a single engine sound.

Traveler reviews

★★★★★

Such a unique experience with no cars at all — cycling the perimeter road with the lake on one side was magical. The fudge really is as good as advertised.

★★★★★

Stayed overnight and the island felt like stepping back in time. Fort Mackinac had great views and the Grand Hotel's porch is something else.

Tom B. · September 2023

★★★★☆

Busy with day-trippers in the afternoon but lovely in the early morning and evening once the ferries thin out. Bring a bike, it's the best way to see it all.
