Old dependable
The title might detract a bit from how nice this campground is, but, I've always been saved by Madison when the park is busy and I need a camping spot. It is one of the largest campgrounds, and has one of the longest seasons. It is centrally located and offers some pretty hikes after you've returned to camp for dinner. There are often elk and buffalo a short drive away in the evenings.
