Mammoth Campground
Campers love the Mammoth Campground with the sheer amount of wildlife in the Mammoth Hot Springs Area. It is common to see Elk and Bison.
Of course, it is also no surprise to see Bighorn Sheep, Mountain Goats, Pronghorn Antelope, and bears. This means that the NPS Rangers strictly enforce the policy that you (especially if you are tent camping) store food in the provided food storage lockers/bear boxes.
The river just north of the campground also attracts numerous bird species, such as eagles, osprey, dippers, and kingfishers, so remember to bring your camera!
Other attractions in the area include the Mammoth Hot Springs terraces, the Roosevelt Arch, Historic Fort Yellowstone, the Albright Visitor Center, and easy access to the park's loop road.
Ranger programs are offered in the campground amphitheater during the summer.
The campground is a high sagebrush steppe filled with scattered juniper trees and Douglas fir trees. The trees provide some shade, but you will want shade covers or hats.
