Splash Into The Spirit of the Season

Christmas Underwater

The Philadelphia area’s most unique holiday tradition, Christmas Underwater, presented by Shriners Children’s Philadelphia, will run from November 21 to December 24. 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.

Festive Photo Ops

Capture your family’s annual holiday card in front of several festively themed photo ops perfect for celebrating the season!

Scuba Santa

The star of Christmas Underwater is Scuba Santa, swimming to town to share holiday cheer with believers of all ages (and species!). Guests can interact and snap selfies with Scuba Santa, who will dive daily among sea turtles, sharks, and stingrays.

Santa Meet & Greet

Meet Santa on land, Friday – Sunday, in his magic workshop to take photos and tell him what you wish for this Merry Fishmas.

World's Largest Underwater Christmas Tree

Visitors can soak in the fish-mas cheer while viewing the World’s Tallest Underwater Christmas Tree, displayed among the Aquarium’s sandbar, sand tiger, and nurse sharks.

Merry Fishmas, Boris (Puppet Show)

The little guppies in your group will enjoy this show as puppet friends Whitney and Finley try to surprise Boris, the shark, with the perfect Fishmas gift.
