This location is first come first serve. There are other sites to reserve in the Pictured Rocks region though.
We were there a couple weeks ago. It's first come, first-served. About half the sites were open when we arrived, and it got no busier during our stay. Lots of mosquitos, so make sure you have bug spray.
I don't think there are any reservations for this campground. It's a first-come-first-served setup.
