Straits State Harbor
October 2026
About
Michigan’s greenest harbor on the Great Lakes. Straits State Harbor is Michigan’s most eco-friendly harbor with eight wind turbines that are anticipated to produce a substantial amount of the electrical energy used to run the harbor. Located just across the Straits of Mackinac from Mackinac Island State Harbor, this harbor gives boaters an opportunity to enjoy the best of both harbors. This harbor is clean marina certified.

Is Straits State Harbor fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
CampHawk watches Straits State Harbor in Mackinaw City, MI for you. We recheck it every 15 seconds, around the clock, and the moment a site opens we send a text, an email and a push notification, with a link straight to the booking page.
