Mammoth Campground — Yellowstone National Park
Mammoth Campground sits in a high sagebrush steppe scattered with juniper and Douglas fir, five miles from the park's North Entrance at Gardiner, Montana. The Mammoth Hot Springs terraces and their boardwalks are right next door, and elk, bison, pronghorn, and mule deer move through this part of the park depending on the season. It opens in mid-April, earlier than most campgrounds in the park, and flush toilets run year-round.
