Lake Huron Campground is a very large and modern RV park. They have 395 sites, but there are a lot of open spaces during the week. I’ve heard on holiday weekends it fills up, but otherwise it’s not very crowded.
The campground has a general store, arcade, heated pool and a nice size lake with a beach area. There are also cabins to rent on the other side of the lake. They have weekend planned activities, mostly for the kids, but they had a Murder Mystery Weekend while we were there, which was fun for the adults too.
