Discover and Go offers free individual and family day passes to San Diego's biggest attractions. Discover and Go is open to all Escondido Public Library patrons with cards in good standing. Passes can be reserved on the Discover and Go webpage, where patrons can select available passes by attraction and date, print or download the passes, and take them to the venue along with a valid I.D. New passes are added at the beginning of each month and are available on a first come, first served basis.
