Tips for Getting the Most Out of Library Passes
- Get cards at multiple systems. If you live near the border of two library districts, you may qualify for a card at both. This effectively doubles your free pass opportunities.
- Book early. Popular passes (Denver Zoo, Botanic Gardens, DMNS) book up fast. Set a reminder to reserve as soon as the booking window opens.
- Check for timed entry. Some venues (Clyfford Still, Museo de las Americas, Denver Zoo) require a separate timed-entry ticket on their website in addition to the library pass. Read your confirmation email carefully.
- Stack with other programs. Library passes are independent of EBT discounts and SCFD Free Days. Use all three programs strategically to visit venues throughout the year.
- State park passes have waitlists. Place a hold as early as possible — you may wait weeks, but it's worth it for a free week of park access.
- Library cards are free to Colorado residents. Even if you never check out a book, the card pays for itself with one museum visit.
