Norris Campground is one of Yellowstone National Park's medium-sized campgrounds managed by the National Park Service, and like the rest of this group, all sites are first-come, first-served only. There are great tent sites in this campground, especially in Loop A near the river, but there are also a fair number of larger campsites for medium to large RVs. This is truly a campground for everyone.
Laid out in three loops, the sites are typical for national park campgrounds, with a moderate amount of privacy. This is a hilly area, so many of the campsites require a climbing up or down a hill to reach the picnic table or tent spot. There are flush toilets and drinking water in the loops. Loops B and C are fairly wooded and offer little in the way of views, but Loop A is more open, and there are great views of the river and surrounding hills.
Norris is unique in having its own geyser basin within walking distance (about a mile). It is also not far from many other great areas like the Hayden Valley for wildlife and the Grand Canyon of the Yellowstone.
Arriving early is a good idea for this campground (like all of them in Yellowstone). It fills up every day, sometimes by 8 or 9 a.m.
