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.

Got to the campground around 7pm and was greeted by the host (?). Received a map of the campground and instructions on water, bathrooms, trash, and quiet hours. Also showers at the hotel! We found our spot, which had a picnic table, fire ring, and bear box. The tent platform is awesome, and made for easy set up. Had a beautiful view. Easy access to the aforementioned amenities. Nice this is it’s within walking distance of a general store, the post office, and the hot springs. Really great place to camp

the bathrooms were very nice and the campsites were super clean. The camp itself is in a really nice area close by to the town.

A great site, with good views and a sense of seclusion, yet close enough to Mammoth for convenience.

Wonderful place to camp EXCEPT for the lack of a place to wash dishes. "Just rinse the soap off in the bathroom," said the ranger. Many folks washed all their dishes there, which was not totally appropriate, but convenient and about the only way to do a decent wash job, despite the lack of space. Other than that mild inconvenience, it was a great place to pitch a tent and wake up to terrific sunrises.

The park was terrific. We loved being able to camp there, and think it’s super important to have these public lands and parks! They should be well funded, supported, and open to all.

The campgrounds were great, well-maintained, and close to the town of Mammoth, which was great to grab an ice cream! A thing to note about our particular site (16) - the tent area was down the hill a bit surrounded by some bushes. We didn't want to walk through bushes in the dark at night, so we opted to pitch our tent in the central area instead. This was all gravel, which meant some of our tent pegs got bent.
