No tent pad at site 66, but there is a nice flat area up in the sage. Bear box was large and nice to have. Site also has picnic table and fire ring. Bathroom was clean, has sinks and mirror in the bathroom as well. Washed dishes in a plastic bin under a water spigot then had to dump dish water down the toilet to not attract bears. Elk bugled all night long and walked right through the campsite many times. Did not see any bears near Mammoth but did in Lamar and Hayden. The campground was conveniently located near Mammoth which has various amenities; as well as a short drive to Gardiner. Would absolutely stay at Mammoth CG again!

The site was uneven but we managed to get our motorhome level. Maybe the description could make it known better. It was site 66 but over all the people and place was awesome. Had a very niceStaff member stop and help us at the site. Great experience.

Entire camp ground was clean and well taken care of. All bathrooms were also clean. Rangers/campground attendants were friendly and knowledgeable.
