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.

Other than there being no showers, we loved being in the park with easy access to everything. Elk sightings in and around the campground and at Mammoth were fun. It was nice to have a home base for 2 nights so we could do most offerings at Yellowstone.

Great location. This particular site has a tent pad on a slightly incline (no steps or footholds) and then a big step up to the tent pad. The campground is great and camp hosts were fantastic. Elk walk through the campground and snack on tree leaves almost daily during the day and can be heard bugling in the distance off and on day and night.
