Hallowmarine

Child in Costume at the Aquarium

Join us for our annual "Hallowmarine" celebration featuring spook-tacular animal encounters, a Halloween-themed scavenger hunt, a costume parade and more! Guests are invited to dress up in costume and learn about animals that creep, crawl, slither and hiss from National Aquarium experts!

On Halloween (Thursday, October 31, 2019), partake in an annual National Aquarium Halloween tradition as divers carve pumpkins live—and underwater!—in our Blacktip Reef exhibit.
