Mammoth Campground
Overview
About This Campground
Set on a hillside at 6,200 ft, Mammoth Campground offers RV and tent sites with fire rings and picnic tables. Water spigots are scattered throughout, but there are no on-site showers; Gardiner provides the nearest public showers about 5 miles away. A Bear country campground with 85 sites, it stays busy in peak season and you should book far in advance on Recreation.gov. Trails to Mammoth Hot Springs are nearby, and quiet evenings are common—though a few late arrivals have been noted.
