Keansburg is turning up the fun this Fourth of July weekend with Family Funfest 2026—a bayshore celebration packed with sunshine, history, and family-friendly adventure. Enjoy the calm, free public beaches (with easy parking), then dive into thrills at Roaring Rapids Water Park with 18+ slides, a lazy river, kiddie areas, and spa pools. Keep the smiles going at the Keansburg Amusement Park, a beloved boardwalk tradition since 1904, and stop by the Keansburg Historical Society
