Yellowstone National Park has more than 300 miles of paved (and often crowded) roads, but a lesser-known dirt road between Mammoth Hot Springs, Wyo. and Gardiner, Mont. offers visitors a chance to follow a historic stagecoach route out of the park.
The Old Gardiner Road is a 5-mile stretch of dirt road that roughly parallels the paved road from Mammoth to Gardiner, but travels through the hills to the west of the main road, rather than along the Gardner River as it flows out of Yellowstone.
