Centennial Beach Season Opening in Naperville

The Centennial Beach Season is the definitive sign that summer has arrived in Naperville. This historic swimming hole, nestled in the heart of the downtown area, offers a unique alternative to traditional chlorinated pools. As a former limestone quarry, the beach provides a vast, four-acre expanse of water that serves as the community’s favorite backyard throughout the warmer months.

Essential Guide to the Centennial Beach Season

The 2026 Centennial Beach Season officially begins on Saturday, May 23, 2026. Opening day typically features a ceremonial “first splash” and serves as the kickoff for residents to begin using their summer memberships. Unlike a standard pool, the water at Centennial Beach is chlorinated but recirculated and filtered through a natural system, maintaining a refreshing experience that feels closer to a lake.

The facility is designed to accommodate visitors of all ages and swimming abilities. During the Centennial Beach Season, the following amenities are available:
