MAMMOTH HOT SPRINGS, Wyo. — As of yesterday, Yellowstone National Park’s (YNP) North Entrance in Gardiner, Montana and the road between the North Entrance and Mammoth Hot Springs (Old Gardiner Road) is open to regular visitor traffic.

The Old Gardiner Road was determined to be the best and only option to quickly reconnect Mammoth Hot Springs to Gardiner, after the floods in mid-June. Originally established in the 1880s as a stagecoach route, the single-lane dirt road has been expanded to two lanes over its entire four-mile length.

YNP wants to remind the public of everyone’s responsibility to use the road carefully to avoid accidents. Steep grades and sharp curves exist. Drive slowly and with caution. Minor road construction work will continue with one-way traffic control and short delays in certain locations on the road. 

The park is also waiving all entrance fees today.
