Boise’s Treefort Music Fest announced its full 2026 lineup Tuesday, revealing over 400 artists performing across 30 venues throughout downtown Boise from September 23-27. Now in its 15th year, the annual festival has grown from a scrappy indie music gathering into one of the most acclaimed multi-genre music festivals in the western United States, drawing an estimated 25,000 attendees from across the country and generating approximately $15 million in economic impact for the Boise area over its five-day run.
The 2026 lineup spans genres from indie rock and folk to hip-hop, electronic, jazz, and world music, reflecting the festival’s longtime commitment to discovery and diversity in programming. While headline acts won’t be announced until July, organizers revealed that this year’s festival will feature artists from 32 countries — the most internationally diverse lineup in Treefort history.
More Than Music: Treefort’s Expanded Festival Ecosystem
What distinguishes Treefort from other music festivals is its network of complementary “forts” — themed programming tracks that run alongside the music and have become events in their own right. Foodfort brings chefs, food producers, and culinary artists to downtown Boise for tastings, workshops, and collaborative dinners using Idaho-sourced ingredients. Filmfort screens independent and documentary films from Idaho and emerging filmmakers worldwide. Yogafort offers free yoga and wellness programming in Julia Davis Park each morning of the festival.
New this year, Treefort is launching Farmfort — a programming track focused on Idaho agriculture, food systems, and the people who grow and produce the food that sustains the state. Farmfort events will include farm-to-table dinners, panel discussions with Idaho ranchers and farmers, and hands-on workshops on topics from cheesemaking to grain milling. The addition reflects Boise’s growing identity as a food-conscious community and Idaho’s agricultural heritage.
“Treefort has always been about celebrating the creative spirit of this place,” said festival co-founder Eric Gilbert. “Adding Farmfort acknowledges that Idaho’s agricultural community is as creative and innovative as any artist on our stages. The people growing our food deserve a spotlight too.”
Economic Impact on Downtown Boise and Ada County
A 2025 economic impact study commissioned by the City of Boise found that Treefort generates approximately $15 million in direct and indirect spending in the Boise area during its five-day run. Hotels throughout the Treasure Valley typically sell out during festival weekend, restaurants and bars in the downtown core report revenue increases of 40-60%, and local retailers benefit from the influx of visitors exploring Boise’s shops and galleries between shows.
The festival also serves as a powerful national marketing tool for Boise and Ada County. Treefort receives extensive coverage from national music publications including Pitchfork, NPR Music, and Paste Magazine, exposing Boise to audiences who might not otherwise consider Idaho as a travel or relocation destination. The Boise Convention and Visitors Bureau has credited Treefort with significantly raising the city’s profile among younger demographics.
Downtown Boise Association executive director Tiffany Robb called Treefort “the single most important event for downtown Boise’s identity and economy.” Robb noted that several downtown businesses have scheduled their openings to coincide with Treefort week, leveraging the festival traffic to launch new ventures.
