Labor Day marks the unofficial start of fall in the Mountain West, and September is one of the best months to get outside before the weather turns. Across Wyoming and Idaho, harvest festivals, rodeos, and small-town celebrations pick up right as the summer crowds thin out — making this one of the best times of year for a weekend road trip.
Best fall festivals in Wyoming
- Jackson Hole Fall Arts Festival — a multi-week celebration of Western and contemporary art, with gallery walks and outdoor exhibits set against the Tetons as they start to turn.
- County fairs and harvest celebrations — communities across southeastern Wyoming continue ag-focused events into September, with 4-H exhibits, food vendors, and live music.
- Small-town rodeo finals — many county rodeo circuits wrap their season in September, often paired with a harvest fair.
Best fall events in Idaho
- Capital City Public Market (Boise) — runs into October with an emphasis on late-season produce, honey, and local crafts.
- Snake River Valley harvest and wine festivals — several celebrations mark grape harvest in Idaho's wine country, a great option for a weekend day trip.
- Orchard season near Emmett and the Treasure Valley — apple picking kicks off at several family-run orchards through the fall.
What should I know about driving rural highways this time of year?
If a festival or market has you driving rural stretches of Wyoming or Idaho highways, keep two things in mind: slow-moving farm equipment sharing the road during harvest, and increased wildlife activity as deer and elk move toward lower elevations in the fall. A little extra following distance goes a long way this time of year.
