2026 Downtown Sioux Falls Riverfest

Saturday, September 19, 2026, 2:00-8:00 PM

Cherapa Place, 345 S Reid Street, Downtown Sioux Falls

Celebrate summer by the river at Riverfest 2026, a free outdoor festival set along the scenic Big Sioux River. This year’s event brings everything you love — live music, delicious food, local retail vendors, and interactive activities — all with a fresh focus on sustainability and river stewardship.

Riverfest is more than just a party — it’s a platform for the community to come together, learn about the importance of protecting the Big Sioux River, and explore simple, impactful ways to support a cleaner, healthier environment. Join local organizations and sustainability partners for conversations, demonstrations, and hands-on opportunities to get involved in ongoing river cleanup efforts.

Downtown Sioux Falls and Friends of the Big Sioux River are hosting a "Big Sioux River Clean-Up" as part of our 2025 Riverfest programming. Join us Saturday, September 19, from 10:00 AM to noon as we clean up the banks of the Big Sioux River in Downtown Sioux Falls. The clean-up will take place on both sides of the river from Falls Park to Fawick Park.

Meet in the CNH parking lot at the Arc of Dreams. Please arrive early, as we'll be handing out trash bags, gloves, and reflective vests. Volunteers will also need to sign a release/waiver form.
