Mammoth Campground offers clean facilities, friendly staff, and a beautiful location near Mammoth Hot Springs, making it an excellent base for exploring Yellowstone. Many reviews highlight the well-maintained bathrooms and accessible water spigots, as well as the stunning views and quiet atmosphere.

Rangers in the campground were great - stopped and talked to us and provided info on the animal behavior. Love the campground -we’ll be back! Would have appreciated a shower house, but wouldn’t stop us from coming back. Love the new reservation system.

Great campground, great hosts. And the hike up Mammoth Hot Springs is easy. Stay away from the elk herds that roll through the campground. They’re beautiful, though.
