Michigan - Marquette City Tourist Park
We've been camping here along the Dead River for two nights. It's a city run park with large sites and lots of tall trees, but not much privacy except for some sites at the end of the loops that are deep inside the trees. There's a small beach and the swimming is good. Lake Superior is literally around the corner, but we don't have bikes and we've stayed hitched up.
We have full hookups, but not all sites do. For us this is a rest stop as we head back east and it's one I recommend. Bath houses are clean and due to the trees, it's been as comfortable as possible, given the heat.
