BigBackyardBash
Big Backyard Bash 2026 brings families together for a full day of inflatable fun, foam parties, competitions, live music, food trucks, and unforgettable memories in St. Charles, Missouri. This is what summer used to feel like — no screens, just one big yard, one big crowd, and the kind of day kids will bring up at Thanksgiving in 2041. Headlining the main stage: Steve Ewing Band — the unmistakable voice behind The Urge, the St. Louis legends who soundtracked an entire generation of summers.
All the good stuff, none of the lines.
Not a carnival. Not a waterpark. A giant outdoor play day packed with the kind of activities your kids will be telling their friends about Monday morning.
