Adventure Pass temporarily shut down in 2025

Due to software issues affecting all libraries using the service, the Iowa Adventure Pass program will temporarily shut down in 2025. Any reservation already made for 2025 will be honored, but we encourage anyone with a current reservation to print those passes immediately. Customers can still make new reservations for passes that must be used by December 31, 2024. The service will return at a later time. We apologize for the inconvenience.
