Centennial Beach in Naperville: Plan a Seasonal Visit

Centennial Beach is a seasonal Naperville Park District swimming facility at 500 Jackson Avenue. For a visit, start with the district’s Centennial Beach page, then check the current hours and daily admission pages. As of October 16, 2026, do not assume a summer schedule applies to a future date. Weather, capacity and special programming can affect access.

What kind of outing is Centennial Beach?

The Park District describes Centennial Beach as a swimming destination in a historic quarry near downtown Naperville. It is a managed facility, so swimming rules, designated areas and staffing matter. Read the facility page before bringing a group or planning a full day.

How do you check opening dates and hours?

Open the district’s Beach Hours page for the current season and day. An archived image, old event listing or search result can show the wrong year. Check weather or closure notices on the day of travel. If the page does not clearly show the date you need, contact the Park District before setting out.

What should you budget and bring?

Use the official daily admission page for current ticket types, residency rules and payment instructions. Read the facility rules for permitted flotation devices, food and personal items. Bring sun protection, water and whatever identification the current admission rules require. Do not assume the prior season’s price applies.

What else is nearby?

The beach is near the downtown riverfront. Pair a swim day with a separate walk using our Riverwalk guide, or look at the free things guide for an alternate plan if weather interrupts swimming. The downtown dining directory can help locate a meal, with each venue’s hours checked directly.
