Centennial Beach | Naperville

Centennial Beach in Naperville, Illinois, is a one-of-a-kind public aquatic facility uniquely set within a historic limestone quarry. It combines the feel of a natural beach with modern swimming amenities, providing visitors a memorable and family-friendly water recreation experience.

History and Setting

Originally a limestone quarry used in the early 20th century, the site was transformed into a swimming facility and opened as Centennial Beach in 1932 to celebrate Naperville’s centennial.

The quarry was filled with water sourced from Lake Michigan, creating a natural deep-water swimming area surrounded by limestone cliffs and lush landscaping.

Today, it spans approximately 6 acres, including 2 acres of open water, making it much larger than a typical swimming pool.
