Yes, islands stay open in winter — just watch your feet.

Yes, most publicly accessible islands (like Mackinac, for example) are open year-round. Winter doesn’t shut them down. But the bridges, boardwalks, and paths turn into ice rinks.

Real precautions: wear traction cleats (Yaktrax or similar) over your boots. Walk like a penguin — short steps, weight over your front foot. Bridges freeze faster than roads, and wind whips them clean of salt. Don’t assume a bridge is clear just because the road was.

If you’re driving, carry a winter emergency kit and check the local conditions before you go. The ferry might still run, but schedules change with ice.

Respect the cold. The islands are beautiful in winter, but one wrong step on a frozen bridge is not worth it.
