Digital Punch Cards

Don't want to purchase a season pass, but plan to visit weekly? Purchase a digital punch card which has a value of 10 daily visits to Sea Lion Aquatic Park for a special rate. If you run out of punches you can purchase another 10 visits or just pay the daily admission. The opportunity is yours and the benefits are endless!

Digital punch cards can be purchased at the Lisle Park District Recreation Center or at Sea Lion Aquatic Park. Each card contains 10 punches and 1 punch is good for one person per visit. For Tot Swim, 1 punch = one child under 6 years of age and one adult 18+ years of age. Punch cards can be shared amongst a family and can be used for a guest. Your punches will be put on a digital card. Give your card to the pool admissions clerk at the pool entrance. The clerk will scan your card and remove punches from your card as you use them. Punch cards are non-transferable and must be used during the current season.
