This park campground in Harrison, Michigan can be loud with road noise depending on where your site is. If you can’t get a campsite on the back loop toward the lake you’ll hear a lot of it. Some sites are even right across a fence from the main road, so pay attention to the layout when booking.
The sites back by the lake also are more private than the other sites, but still not very secluded.
And be aware of this unusual nugget: this state park does not sell firewood, although several stores nearby do.
