Splash Into The Spirit of the Season

Christmas Underwater

Adventure Aquarium hosts the most unique holiday tradition in the Philadelphia area -- Christmas Underwater, presented by Shriners Children’s Philadelphia! During Christmas Underwater, guests can surf the yuletide and explore a winter waterland filled with holiday d-eel-ights like Scuba Santa, indoor snow flurries, the World’s Tallest Underwater Christmas Tree, and merry more!

Other holiday delights include the Aquarium’s many holiday-themed photo ops, festive Gift Shop offerings, twinkling lights, jaw-some holiday décor, and the chance to write letters to Scuba Santa.
