We had a great time! And given the current situation in Yellowstone NP, we feel very fortunate to have had the time there that we did. Campground was as we expected and the campground hosts were friendly & helpful.

Seeing the Elk. Camp ground was great.
Would be good to have somewhere in the complex where you could do laundry.

I can't say enough good things about this campground. The wonderful man who checked us in was so sweet and informative. The hosts were friendly and visible checking out the campground every day. Our site was absolutely amazing! Clean and in the best spot! We had elk visiting every morning to graze. The convenience to Mammoth Hot Springs and the Lamar Valley was an added bonus. Best campground we stayed in while in Yellowstone!

We spend our first night on 67 which was noisy and uneven. This site is even.
It is almost just as noisy though. Trucks thundering up and down the road all night.
As the campsite is situated right within the curve you can hear them all the way.
Staff was very nice.

Horrible experience! Trucks thundering up and down the road late at night and in the early morning hours. We couldn‘t sleep at all.
Site was very uneven and we couldn‘t level our Rv (25 ft).
Staff was very nice!

Nice campground with sites large enough for bigger rigs. The bathrooms were clean and it was fairly quiet. The location is wonderful and it’s an easy drive to Tower Falls. We easily drove the top half of the Yellowstone loop to the Grand Canyon and Norris Geyser Basin.

Well maintained, clean bathrooms, friendly hosts
We utilized the walking trail up to Mammoth Springs to walk the boardwalks, go to the visitors center, the grill, and the general store for ice cream!

We stayed two nights at Mammoth campground and loved it. We backed up to the road and the scenery was fantastic. Although there werent showers, they were available at the Mammoth Hotel for $7. We walked across the street to the hills and hiking trails along the river and saw elk and even a wolf. It was wonderful and who could beat the price!
