Rahway River Park is a 120-acre public park managed by Union County, featuring significant portions of the Rahway River watershed. The park provides extensive athletic infrastructure, including a synthetic track, multiple sports fields, and basketball courts. A central feature is the public swimming pool complex, which operates seasonally during the summer months. The grounds include paved walking and cycling paths that wind through wooded areas and open fields. A dedicated picnic grove provides space for large gatherings near the river. The park frequently hosts local community events and high school athletic competitions. It maintains a mix of manicured recreational spaces and natural riparian corridors.
