World’s Largest Brat Fest is a beloved Madison tradition that takes place each Memorial Day weekend, bringing together food, music, and community for an unofficial kickoff to summer. Held at Willow Island at the Alliant Energy Center, this free, family-friendly festival features sizzling bratwursts, live music across multiple stages, a carnival, fireworks, and activities for all ages. What started in 1983 as a small customer appreciation cookout has grown into a major nonprofit fundraiser, raising millions of dollars for local charities while celebrating Wisconsin’s iconic bratwurst culture.
