The Antioch Aqua Center's swimming pool has 5 lanes and is 33.33 yards long. It is in Williams Park behind the Antioch Library. Williams Park is accessible from Williams Street (see map below). NOTE: Williams Street is closed during little league games. If Williams Street is closed, you may access the pool via the Library entrance on Main Street north of Williams Street or via the Metra parking lot off Depot Street. Please do not park in the library's parking lot! There is substantial parking southeast of the pool along the train tracks.
