Autumn Weather

The weather in Yellowstone during the autumn months can vary greatly between weeks and even days. Temperatures typically fall between 20 degrees Fahrenheit and 65 degrees Fahrenheit. Days get gradually shorter as winter nears, and temperatures tend to drop rapidly once the sun goes down.

Fall Hiking in Yellowstone

Getting out into the backcountry on foot, even if you only go a mile or so from the trailhead, is a great way to see the fall colors without the distraction of too many other people. You also stand a good chance of seeing wildlife as they get ready for the coming winter. In addition to bear and elk, you may well see pronghorn, bighorn sheep, deer, moose and eagles.

Biking in Yellowstone during Autumn

As in the spring, there’s a brief period in November in which most roads are closed to wheeled vehicles as park officials prepare them for winter use. Lucky for cyclists, sections of the roads remain open to those on bicycles, as well as to walkers, joggers, rollerbladers, roller skiers, etc.

See route map at

The following sections of the Grand Loop Road are open:

  • Mammoth Hot Springs to West Yellowstone
  • Snake River Entrance Station to West Thumb Junction
  • East Entrance to the east end of Sylvan Pass (6 mile corner)
  • Tower Junction to the Chittenden Road as conditions allow
  • Madison Junction to Old Faithful
  • The road from the North Entrance at Gardiner, Montana, to Cooke City, Montana, at the park’s Northeast Entrance, is open all year to cyclists and automobiles, weather permitting.

Fall Fishing in Yellowstone

Fall can be the best time of year to catch the largest and most beautiful browns of the season. Most of the brown trout in southwest Montana will spawn between late-October and mid-November. As water temperatures drop, late season anglers often see the big fish move out of their lairs and become more vulnerable to flies. They become much more aggressive as well. Browns want bigger food than they did in August and they are more willing to chase it down to get it.

Elk Go A Little Crazy During Rut Season

Autumn is arguably the best time to check out the elk roaming around Yellowstone because visitors not only get to see these beautiful ungulates, they get to hear them. Elk enter their breeding season during the fall, called the rut. During this time, male elk are vying for the attention of females, and they do this by bugling, letting out a sound alternately deep and high-pitched.

Elk also begin migrating during the autumn, leaving the high elevation grasslands that will soon be covered by snow. The park’s largest herd of elk spends the winter in the Lamar and Yellowstone river valleys from Soda Butte to Gardiner, Mont. It may also move out of the park and take up residence in the Gallatin National Forest or other private lands. Jackson’s National Elk Refuge provides a winter home for roughly 7,500 elk.

Bears Get Ready for Hibernation

Bears spend the autumn preparing for their long winter of hibernation, so you’re likely to see them foraging for nuts and other snacks to keep in their dens. Bust out the binoculars when you’re cruising down the Buffalo Bill Scenic Byway, the road to Yellowstone’s east entrance, or taking the Chief Joseph Scenic Byway, which leads to the northeast entrance.

Bison Migrate For Winter Feeding Grounds

Most bison head down to lower elevations during the fall because Yellowstone winters can be so severe. This annual migration helps them to better find the resources they need once the snow piles up. Hundreds of bison head to Lamar Valley, Mammoth Hot Springs, the Old Faithful area, and sometimes cross Yellowstone’s border into Montana farmland.
