World's Largest Bounce House Brings 50,000-Square-Foot Attraction to Antioch Event Park

The world's largest touring inflatable amusement park is coming to East Contra Costa County this fall, transforming the Contra Costa Event Park in Antioch into an expansive 50,000-square-foot outdoor family entertainment complex. Produced by touring event company The Big Bounce America, the massive interactive attraction will welcome guests across two consecutive October weekends, operating Saturday and Sunday, October 17–18 and October 24–25. The limited engagement brings four record-setting custom inflatables, giant climbing towers, and open-air athletic challenges to the historic fairground site near the San Joaquin River delta.

The arrival of the international touring attraction provides a major recreational draw for families, youth sports leagues, and thrill-seekers across Antioch, Pittsburg, Brentwood, and Oakley. Beyond offering high-energy outdoor recreation for children and adventurous adults, the multi-day festival generates welcome patronage for neighborhood businesses, casual dining establishments, and hotels situated along the Highway 4 corridor. Fairgrounds officials noted that hosting large-scale touring attractions enlivens the fairgrounds year-round while offering safe, supervised, and wholesome weekend entertainment for local residents.

The Contra Costa Event Park, formerly known as the Contra Costa County Fairgrounds, has served as a central cultural and agricultural gathering hub for East Bay residents since its founding in the late nineteenth century. Governed by a dedicated board of directors in partnership with county supervisors and the City of Antioch, the venue routinely hosts regional livestock exhibitions, youth fairs, and commercial expos. Venue managers work closely with municipal public safety personnel, building inspectors, and the Contra Costa County Fire Protection District to verify safety protocols and wind resistance standards for large temporary structures.

The centerpiece of the touring complex is an extraordinary 24,000-square-foot bounce house featuring towering inflatable slides, ball pits, and a live performance stage with a resident disc jockey. Adjoining installations include The Giant, a continuous 900-foot-long obstacle course boasting fifty distinct physical hurdles, alongside Sport Slam, an octagonal athletic arena equipped with basketball hoops and soccer nets, and airSPACE, an intergalactic zone filled with moon-crater pits and extraterrestrial aliens. The event park is located at 1201 West 10th Street in Antioch, with ticket pricing starting at $35 for timed three-hour admission passes and administrative information available by calling (925) 757-4400.

Because daily attendance is strictly capped to ensure safety and prevent overcrowding inside the inflatable structures, organizers require guests to reserve specific entry time slots online prior to arriving at the fairgrounds. On-site concessions, regional food trucks, shaded picnic pavilions, and free paved parking will be available throughout all operating hours on both weekends. Families and group organizers can review session schedules, age-specific toddler or adult sessions, and footwear requirements by visiting the official Big Bounce America tour website.
