What Guests Are Saying
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. However, some campers noted a lack of shade, noise from nearby traffic, and limited trail access, but overall, the campground is highly recommended for its amenities and scenic surroundings.

Elk were common around the campground - very cool. Facilities were some of the nicer ones I have experienced at national parks. Sites were large and comfortable. If you are sleeping in a tent, you will most likely need to use rocks to secure it as the ground is quite hard!

Beautifully maintained, quiet campground. Perfect place for elk watching in the fall and close to lots of great hikes in the Northern Range.

Great campsite and the ranger onsite was very helpful. Loved the wildlife and ability to hike to town. Town with store, gas and a few restaurants and gift shops. The Elk in town were a fabulous site! Also close hike to the "Hot Springs". Great trails!

Yellowstone in the fall is like nothing else. Where else would you have a bull elk bugling through your camp at 1:30 in the morning?

The hosts are fantastic. The sites are big enough and not too close to each other. We needed the sun for our solar panel so I don't complain but I noticed that it's not a lot shaded. You can walk to the main Mammoth area (visitor center, stores, restaurants). But the campground is in the middle of a very busy road switchback and it's noisy.

Camp site was good but the best part was the Elk through the camp site every day and view was great from our site.

Wish there were showers.
On a map, the campground looks close to the visitors center/hotel/store, but it actually is up a very steep trail so you'll likely drive.
Location can be windy. Stake you tent well. Lots of Elk. Restrooms are quite nice for a National Park campground.
