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.

Our site is very exposed. Tent pad was located at lower level compare to the picnic table and parking. Though no shower available on site, the park ranger mentioned the hotel might provide it for $5 or $6, though we didn't check it out.
I didn't realize Gardinar was so close. I would have spent some time to explore the town.

I was fortunate to book a single tent site a few days before arrival. The campground provided exactly what I had expected and was easy access to the hot springs.

The campsite was great! Our tent fit nicely on the appropriate gravel spot. I would say people are a little closer than other spots I have stayed, but everyone was very respectful. The bathrooms were well maintained.
