How to Participate

This March, Baltimore City children in fifth grade and younger can visit any Pratt location and show their library card to get a Read to Reef bookmark, while supplies last.

Borrow, read, or listen to someone read any five aquatic- or conservation-themed books and record them on your Read to Reef bookmark. You can also register and track your progress online with Beanstack.

Participating children have through June 19, 2022 to complete the program and visit the Aquarium.

Need ideas to get started? Check out a PDF list of recommended Read to Reef books. You can pick up library books in person, or browse eBooks in our Digital Library.

On March 16, celebrate the Spring 2022 season of the Read to Reef Book Club with Fun & Facts in the Forest, a virtual visit from children's book author Lulu Delacre!

Reserve Your Tickets

Once you have read and logged five books, you can reserve up to four admission tickets to The National Aquarium.

Social distancing and other safety procedures will be in place during your visit. All guests must reserve their visit date and entry time in advance online using the reservation portal at

To reserve your timed entry slot, use the code printed on the bottom of your Read to Reef bookmark. This code can only be used once to redeem four tickets of admission. Children two years old and younger do not require tickets, and if you do not use all four tickets in your transaction they are forfeited and cannot be used on a separate day.

Spring 2022 blackout dates are April 15, 16, and 18, and May 28, 29, and 30.

Before your visit, please review the National Aquarium’s updated protocols and procedures in response to COVID-19 before you arrive on-site.
