Madison Campground is a National Park Service campground in Yellowstone National Park, Wyoming, 14 miles inside the West Entrance where the Gibbon and Firehole rivers join to form the Madison River. Our Yellowstone guide calls it the natural choice for anyone entering from West Yellowstone: elk and bison wander through, and the fly fishing from camp is legitimate. It is one of the big developed dry campgrounds and suits mid-size and larger rigs that can manage without hookups.
