Know before you go

Tips for visiting Mackinac Island.

Ferries cross from Mackinaw City and St. Ignace; on summer weekends, arrive early to secure parking near the docks.
Bicycles are the island's main transport — rent on arrival or bring your own on the ferry, and keep right on crowded Main Street.
Stay overnight if you can: the island grows quiet and lovely once the last day-trip ferries depart.

Travel well

Make it a good visit.

Check access before leaving.

Opening hours, parking, permits and step-free access change by season. Confirm your needs with the official destination; a map pin is not an entrance.

Give the shoreline time.

Leave room for weather delays and a quieter side trail. Stay on marked paths, respect closures and support the local communities that make the coast special.

Travel thoughtfully

Look beyond the air forecast.

Waves and water temperatures can tell a very different story. Use marine forecasts and local beach advisories before any water activity.
