Annual Events in the Treasure Valley
Last updated: 2026-06-11
The Treasure Valley's calendar runs on a dependable rhythm of signature events. Spring kicks off with Treefort Music Fest, the multi-venue music-and-everything festival that takes over downtown Boise typically in late March, and the Capital City Public Market returning to 8th Street on Saturdays from roughly mid-April. By June the festival season is fully open: Eagle Fun Days and Meridian Dairy Days bring small-town parades and carnivals, and the Boise Music Festival packs Expo Idaho for a one-day lineup.
Summer is the valley at full speed. For the 4th of July, Boise's main celebration and fireworks are traditionally at Ann Morrison Park, and Meridian, Nampa, Caldwell, Eagle, Star, and Kuna each run their own shows — check each city's calendar on our Events page for this year's details. Free Wednesday-evening concerts run all summer at Alive After Five on the Grove Plaza. In July, Nampa hosts the Snake River Stampede, one of pro rodeo's classic stops, and the Canyon County Fair runs in Caldwell.
August into fall is fair-and-rodeo season: the Western Idaho Fair (the valley's biggest, typically ten days at Expo Idaho), the Caldwell Night Rodeo, then hot air balloons filling the morning sky over Ann Morrison Park for the Spirit of Boise Balloon Classic around Labor Day week, followed by Art in the Park in Julia Davis — one of the Northwest's largest outdoor art fairs. Winter closes the year with the Boise Holiday Parade downtown, Winter Garden aGlow at the Idaho Botanical Garden, and Caldwell's Winter Wonderland lights along Indian Creek.
