Halloween at the Seattle Aquarium

Celebrate spooky season at the Ahhhhquarium!

Trick or treat around our habitats to snatch some candy or a non-snack prize while learning about the mesmerizing (and sometimes mysterious) marine world. Costumes are welcome!

Remember, your ticket gets you access to all event activities, daily activities and our three buildings—including the Ocean Pavilion. And you’re supporting important marine conservation work. Thanks for being an ocean champion!

A small shore bird in a grassy and sandy habitat at the Seattle Aquarium walks behind a skull decoration placed in the habitat as enrichment and part of the Aquarium's annual Halloween celebrations.

Prepare yourself for a frightfully fun day. Join us for a spooktacular story time. Watch our multi-talented divers carve pumpkins underwater and vote on your favorite creations. See master pumpkin carver Russ Leno in action as he transforms a giant pumpkin into a gourd-geous work of art. Creep upstairs to the Seattle Aquarium Café for our special menu featuring bat-shaped chicken nuggets and apple cinnamon churros. 

Up for a challenge? Take part in our bone-chilling scavenger hunt featuring x-rays of some familiar faces at the Aquarium seen in a curious new light.

Specialty items available in the Seattle Aquarium Café

  • Caramel Apple Churros—$12
  • Bat Nuggets—$16
