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.

We loved the campground! It is tiered so you have a clear view of the beautiful hills at most sites. This also makes it feel more private. Most (maybe all?) sites are pull through which was great. No showers on site, there’s a laundromat that has 3 showers in Gardiner, and it cost $5 (in quarters-they had a change machine) for 10 minutes. Bathrooms at the campground were clean and nice though. Bear boxes at every site. Elk walked through the campground a lot which was cool for the kids! Great location to get to town (Gardiner) or head right into Yellowstone on the top of the figure-8 Grand Loop. There is road noise because you’re right in the corner of a switchback, but we still loved it for the location and view!
