Visiting this fort is always much fun. There are two major historic forts on the Mackinaw straits. The one on the Mackinaw City side of the pond and the one on the hill on Mackinaw Island. Both were occupied at various times by England and France as they battled for control of the straits. The one we toured today was the one on the Mackinaw City side located nearly underneath the bridge.
Dad remembers going on the tour as a child and there was a skeleton in one of the lookouts. The first thing Dad checked out was to see if that skeleton was still there and sure enough it was.
The tour is mostly a self tour with mini tours going on from time to time. They shoot off the cannon which is pretty cool and very loud. Bring your earplugs for that.
