The Adventure Pass program offered by public libraries around Iowa, which provides free passes to attractions such as museums and botanical gardens, will be suspended at the end of this month. Plymouth Rocket, the software company that provides the reservation system and hosts the site for the passes, has “decided to sunset” its event registration and event calendar software.  

“We know you all love the Adventure Pass, and we are working on finding a new reservation software to get it back up and running as soon as we can,” the Grimes Public Library (GPL) said in a social media post

GPL partnered with Blank Park Zoo in Des Moines to launch the Adventure Pass program in 2017. At first Grimes was the only library and the zoo was the only location in the program, but other libraries soon asked to join and the number of venues accepting passes expanded. By the time the Iowa City Public Library and Cedar Rapids Public Library joined in 2022, library cardholders 18 and older could reserve free passes for two adults and two children a day at a variety of venues, from the Grout Museum District in Waterloo to Reiman Gardens in Ames and the Science Center of Iowa. Currently, almost 80 libraries participate in the program. 

“The calendar is still open for new reservations thru December 31st,” according to GPL. “Reservations that were previously made for dates past December 31st will still be honored. However, new reservations are not being taken for dates after December 31st.”

Anyone who has already reserved passes for 2025 should print it out before Dec. 31.
