The fall colors in the Pacific Northwest states of Idaho, Montana, Oregon, and Washington may vary from year to year depending on weather conditions, but you're always in for a vibrant view on your autumn trip to the region.
Warm, dry falls — which often occur in the Pacific Northwest — produce breathtaking hillside panoramas, but the occasional rainy autumn can cut the foliage season short. The United States Forest Service fall color information guide is your best resource to consult before planning your leaf peeping trip.
The types of trees and shrubs across the region that provide color include vine maples, larch, and aspen. The vine maple, which often lines Pacific Northwest hiking trails, turns to hues of yellow, orange, and red; the larch and aspen leaves transform to gorgeous shades of yellow and gold. Since these trees are often intermingled with evergreens, the fall foliage display is both rich and varied.
Fall Foliage Season by State
Due to the volatile nature of the weather in the Pacific Northwest, the exact dates that leaves are expected to start changing colors and fallings are hard to predict. However, you can generally expect to see bright yellows, reds, and oranges from mid-September through at least mid-October in all four states.
- Idaho: Best viewed while driving down scenic byways from late September through October. Consult the Intermountain Region Forest Service for more exact dates of fall foliage this year.
- Montana: Best viewed while driving through national parks and forests from late September through mid-October. The colors vary depending on elevation, and you'll need to have a car equipped with four-wheel drive to access some roads.
- Oregon: Best viewed while driving along scenic highways from mid-September through mid-October; however, color conditions vary daily based on humidity and fog density. You can call the free Oregon Fall Foliage Hotline for daily updates on the status of the foliage.
- Washington: Best viewed in the Columbia River Gorge and the Cascade Mountains from mid-September through mid-October. Washington State also offers a free hotline with daily color reports.
Changing daily weather conditions can drastically affect the visibility of fall foliage and even how bright the leaves appear — especially closer to the Oregon and Washington coasts, where thick fog lingers well into the day for much of the season. As a result, some days are better for viewing fall foliage than others; you should check local weather reports for up-to-date information on visibility.

Columbia River Gorge National Scenic Area in Oregon
Located along Interstate 84 in Oregon, the Columbia River Gorge National Scenic Area includes over 80 miles of forests rich in bright fall colors from mid-September to mid-October each year.

Beartooth Highway in Montana
Considered one of America's best scenic drives, Beartooth Highway (United States Highway 212) is a 68-mile byway that passes through the Custer, Shoshone, and Gallatin national forests. Although most of Beartooth Highway is located in northern Wyoming, it connects the cities of Cooke City-Silver Gate and Red Lodge in southern Montana.
Keep in mind that about 50 miles of this scenic route will close for the winter season around mid-October. While you can still take U.S. 212 West from Cooke City, you'll need to turn off Beartooth Highway about 18 miles into your trip after the snow starts to fall, as most of the road will be inaccessible to vehicle traffic.
Instead, you'll take State Highway 296 south through the Shoshone National Forest to Wyoming Highway 120 West, which turns into Montana Highway 72 at the state border. Once you get to Belfry, you'll turn left onto State Highway 308, which takes you to Red Lodge. This detour will add about 40 miles (and an hour) to your trip, but you'll still have plenty of opportunities to see fall foliage along the way — even if snow has already blocked U.S. 212.
