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.

Mammoth was the perfect stay for us. We felt truly surrounded by the beautiful nature of Yellowstone, & got to enjoy the elk! No showers, but we knew this going in & planned accordingly. Would definitely stay again!

The camp hosts were wonderful. Every site was clearly labeled, clean, and spacious. The bathrooms were well maintained and the facility in general was great. We also felt that the area was patrolled nicely for those whom were not occupying the campsites, and there was no overflow of other park goers that were not suppose to be in the campground.

Great campground and jump off point for exploring the northern parts of the park. We found it very convenient for our first nights in the park since it is only about 1.5hrs drive from Bozeman. Very clean, easy to access bathrooms. Saw and heard several elk right from the campground!

We had such a great time and really enjoyed the camp site. We were lucky to make last minute reservations.
Bathrooms were clean and close to our site, when first driving in we even got surprised by some elk wandering through the site which we were told is very common.

This is a desert campground as opposed to a more forested campground. Toilets were clean, site was acceptable, enjoyed my stay.

Site 24 is great for all types of RVs but there are no spots such as tent pads to put your tent. If you're in a tent you'll have to put it in the driveway on the gravel and it might be difficult to put in stakes in the ground.

Great spot to spend the night while traveling through Yellowstone. Fun little hikes next door to the campground and the elks are comfortable hanging out there. Super friendly Host and funny woman who checked us in. Couldn't have been better.
