Yellowstone National Park encompasses 2.2 million acres, spanning over 3,472 square miles in Wyoming, Montana, and Idaho.
While most of Yellowstone’s highway system lies at 7,500 to 8,000 feet (2,275-2,427 meters) above sea level, the rest of the park’s elevation runs the gamut. The lowest elevation, 5,314 feet (1,608 meters), is at the park’s north entrance in Gardiner, Montana; the highest elevation, 11,358 feet (3,640 meters), rests on the eastern boundary at Eagle Peak.
