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.

The campground is great if you are just arriving and leaving the park. It took us just about 30 minutes to get to Hayden valley at dawn. Running water was nice too. As you would expect the sites are fairly close together but folks were courteous for the most part

This is a terrific campground. I had a site along the eastern edge with views of the deep Gardner River canyon. In the morning a herd of elk paraded by, with much bugling. Just a bit up the road along Beartooth Highway you can easily see herds of buffalo (on the road, too, naturally!). Plus of course it is minutes away from Mammoth Hot Springs. It has good cell service. The bathrooms are nice and well kept with flush toilets. I was sad to leave and would totally stay here again.

You can only pitch your tent in the gravel driveway they give you. Bring loads of bedding. It’s the warmest part of Yellowstone so it’s decently warmer at night. Its right next to the employee parking for the Mammoth lodges so there is cars constantly going up and down the road next to you at night. Having a fire when you can is a little nerve wracking, as there is a dry sage brush everywhere through the campground. Despite this it is a very well kept campground and the staff there were very friendly.

Yellowstone never disappoints. I particularly enjoyed Lamar valley and viewing the wildlife. I saw some life birds as well as bear, buffalo, and wolves. It was pretty awesome. I also loved the short hikes that are attached to many of the viewing areas.
Mammoth campground was clean and the sites were super easy to get in and out of. I had been on the road for a while so it was nice that it was so close to town and I could stock up on groceries, visit a nice restaurant, and do some general town stuff as well. I will definitely try to camp there again. It's such a big park that you need more than a week to see everything.
