Ruby Creek Recreation Area campground is a  Bureau of Land Management campground with 22 campsites.  This campground is in a flat grassy area along the Madison River,  some bushes and small trees are along the river and in the campground, but almost all sites are in few of each other .  Campground has water, vault toilets, picnic tables, and metal fire rings.  This is a Pack in, pack out campground. I have stayed here twice and each time their were only a couple others camped here.  Sites are $12 a night.  Good fishing to be found in the Madison River.  Far enough from Yellowstone to avoid the crowds, but not to far away.
