June 21 is the longest day of the year. By day, visitors have the maximum number of hours to enjoy the Riverwalk. A scaled version of our solar system, diverse entertainment, refreshments, astronomical exhibits, and relevant speakers will highlight the day. After dark, visitors can look through telescopes at the stars and planets as they engage in fellowship with family, friends, and new acquaintances.
Admission is free.
However, donations large and small will be accepted for future educational activities and enhancement of the Naperville Riverwalk. All Rights Reserved.
