This is my least favorite campground in Yellowstone. It's very dry, arid, but quiet. It's best features are its location near the Mammoth visitor's center, etc. It's accessed off the traffic circle just beyond. Didn't appear to have any looky-loos driving through the campground. Gardiner is just a short scenic ride down the mountain. Oh yeah, flush toilets!

Fairly beautiful campground with lots of elk roaming around. Not much shade at our site, sadly...but we enjoyed our time.

Nice quiet campground we can recommend for a stay in the north of Yellowstone. Has clean toilets but no showers. Was a little bit tricky to level the RV because the pitch was sloping in two directions. We would come back!

We had a great stay at Mammoth campground despite hot weather. Spent 9 nights in site 60, nice spot. The large sage brush bushes give the sites a little privacy. The camp hosts were friendly and helpful. Clean bathrooms.

This campsite is quiet, beautiful and beautiful. The hosts are well organized. The only drawback is that it’s far away from most trails and the one trail to mammoth hot springs is not a convenient one. It’s a vertical climb, so you can’t take a leisurely stroll to dinner or to the springs. Due to the physicality of this trail, most people will need to drive from the campsite and fight other park goers to gain access to resources and activities. Even if you’re physically in shape and can handle the hike it will make you sweat and scramble to the top. There’s no shower on site, and you have to pay the hotel and drive to their shower. That seems awkward. I did love the campsite, so besides the lack of convenience I’d definitely stay there again if I was in the area but wouldn’t go out of my way to stay here. I recommend the lower camps if you want to see elk grazing! There really wasn’t a bad campsite though. All of the sites have a view.

Mammoth is a gorgeous campground. It was quiet and the sites were roomy and pleasant. The sunset was an added bonus. The camp hosts were so nice and welcoming. We would love to stay there again.
