Anchored in the 760,000-gallon Ocean Realm exhibit, the 18-foot custom illuminated evergreen tree is surrounded by sandbar sharks, sea turtles, and giant stingrays. The seasonal highlight is Scuba Santa, who dives daily in full festive gear to wave, blow bubbles, and interact with young visitors through the floor-to-ceiling viewing window. Kids can also explore the Snowtastic flurry walk-through with indoor flurries, visit glowing holiday jellyfish exhibits, and mail letters directly to the North Pole at Santa's postal box. Fully accessible with ramps and elevators throughout for strollers. ## Similar picks in Philadelphia - [Macy's Christmas Light Show & Dickens Village](https://grassyknees.com/philadelphia/activities/macy-s-christmas-light-show-and-dickens-village--listing-06143d100c3e0d5303a7c618) — Nov 27 – Dec 31 · 10:30 AM – 8:30 PM · Macy's Center City (Historic Wanamaker Building) · All ages · Free · checked Nov 4.
