Northern Idaho
Spotlight Event: Coeur d’Alene Downtown Oktoberfest
September 18th – 19th, 2026 | Downtown Coeur d’Alene, ID
Raise a stein in downtown Coeur d’Alene as participating businesses along the main drag transform into a two-day Oktoberfest celebration, Idaho style. Travel through downtown sampling crisp German-style beers and ciders at stops along the way, with live music, food, and the full energy of a walkable lakeside city in the heart of fall. It’s a great excuse to spend a weekend in CdA as the leaves start to turn and the summer crowds thin out.
Southwestern Idaho
Spotlight Event: Spirit of Boise Balloon Classic
September 2nd – 6th, 2026 | Ann Morrison Park, Boise, ID (Launches 7:15am – 9am daily)
September in the Treasure Valley opens with one of its most spectacular annual traditions. The 35th Spirit of Boise Balloon Classic fills the sky above Ann Morrison Park with more than 50 hot air balloons lifting off just after sunrise each morning — and the whole thing is free to watch. The signature Nite Glow event on Friday, September 4 lights up the evening sky as tethered balloons illuminate in the dark from 4pm to 10pm in a display the whole family can enjoy. Come early, bring blankets and a camera, and plan to make a morning of it along the Boise Greenbelt.
Southern Idaho
Spotlight Event: Twin Falls County Fair & Magic Valley Stampede Rodeo
September 2nd – 7th, 2026 | Twin Falls County Fairgrounds – 215 Fair Ave, Filer, ID 83328 (Gates 10am – 10pm daily)
Southern Idaho’s biggest late-summer tradition returns for six straight days of fair fun and rodeo action in Filer. This year’s theme, “Stars, Stripes, and Stampedes,” brings a patriotic flair to a fair that draws visitors from across the Magic Valley and beyond every Labor Day weekend. Expect PRCA rodeo competition, live grandstand concerts, a carnival midway, livestock shows and exhibits, plus classic fair food at every turn. Admission is just $8 at the gate, making it one of the most affordable family outings of the season. Weekday visits offer shorter lines and a quieter midway — but the holiday weekend brings the biggest crowds, the fullest rodeo schedule, and the most electric atmosphere.
Central Idaho
Spotlight Event: Ketchum Oktoberfest
September 18th – 19th, 2026 | Champions Meadow, Ketchum, ID (Cornhole Tournament 11am – 4pm; Full Event Throughout the Weekend)
Sawtooth Brewery brings the 13th annual Ketchum Oktoberfest to Champions Meadow for a full weekend of German-inspired fun, Idaho style. Buy a stein, choose a beer, grab some food — and then work your way through live music performances both days, a Cornhole Tournament, Beer Olympics, Stein Hoisting Competition, and Axe Throwing. Teams of four can register to compete for the coveted 2-liter Das Boot. Whether you’re a craft beer enthusiast or just looking for a lively fall weekend in the Wood River Valley, this is one of the season’s best reasons to head to Ketchum.
Eastern Idaho
Spotlight Event: Eastern Idaho State Fair
September 4th – 12th, 2026 | Eastern Idaho State Fairgrounds – 97 Park St, Blackfoot, ID 83221 (Gates 10am – 10pm daily)
The region’s biggest annual event is back for its 124th year, and this one carries extra meaning — the 2026 Eastern Idaho State Fair celebrates America’s 250th birthday with the theme “Red, White and Blue Jeans.” Over 250,000 visitors are expected across nine days of livestock shows, 4-H and open-class exhibits, carnival rides, fair food from more than 270 vendors, a full slate of rodeo and motorsport events, and three major grandstand concerts: Flo Rida on September 4, Gabriel Iglesias on September 10, and country singer Nate Smith closing things out on September 11. Blackfoot sits just 25 minutes from both Pocatello and Idaho Falls, making it an easy day trip — or a full fair weekend — for families across Eastern Idaho.
