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.

Clean sites. Clean bathroom. There is a nice trail down by the amphitheater that goes all the way up to Mammoth village. On campground map that is given to you at checkin it is well marked as “ trail to Mammoth”. In reality the sign at the amphitheater was overgrown by grass, way up from road. Posted on a random rail out of site from road, it says “ trail to top of hill”. Poor maintenance and attention to this!! Easy and 15 minute or less hike to heart of Mammoth from campground. Saves auto traffic. Fun stroll. Can’t understand why they are hiding this trail. Understaffed I guess.

Beautiful location. Fantastic campground hosts. Friendly/pleasant park rangers. Respectful campers. A number of hikes right from the campground and about a mile hike to the Mammoth Dining room. The sites are clean and level and easy to pull through. I really like it there.

Great site at the end of the loop. Afternoon shade. Tent fit best in driveway. Unfortunately, many of the restrooms were closed, no one at check in.

This is a really great campground location for exploring Yellowstone upper loop!
The campsites don't have a huge amount of shade so plan accordingly. There are plenty of potable water spickets and the bathrooms are clean and well lit.
Campstaff and rangers were helpful, knowledgeable and friendly.
Will def add this to out return camping locations.!
**tent pads are RAISED so if you have a bigger tent then what you booked it will not fit lol. Just a heads up for this location.
