Yellowstone in September
September rewards a flexible road plan with checked lodging and dining dates. Do not assume summer services, mild weather or every high route will remain available.
Plan the visit
Make the trip fit you
Make the day fit the journey
Keep the high route conditional
Snow and freezing temperatures can change roads or walks. Check the current road status before linking Canyon with Tower over Dunraven Pass or making the two-park connection. [1][8]
Give wildlife space
Watch from designated pullouts, without approaching or blocking animals. Keep at least 100 yards from bears, wolves and cougars and 25 yards from other wildlife; move farther away if needed. [2]
Keep Mount Washburn out of an autumn plan
NPS advises against this hike in September and October because grizzly bears frequent the area. Choose another open outing and check local restrictions. [14]
