Experience a frighteningly fun time for the whole family at the Aquarium this Halloween! It’s no trick that we’ve got a special treat for our guests this year: Come meet characters from Nintendo’s Animal Crossing: New Horizons and take photos with them.  

And join us for some of the Aquarium’s Halloween traditions like underwater pumpkin carving and trick-or-treating at SEAlebrity habitats. Costumes are welcome and encouraged!

Calling all marine-loving teens! The Seattle Aquarium invites all students ages 12–18 to the 2023 Youth Ocean Conservation Summit. Come learn about conservation work from local experts and connect with other passionate young people.

Put on your coolest costume and head down to our Halloween bash! Adults will take over the entire Seattle Aquarium for this 21+ event, featuring DJs, live music, a costume contest, opportunities to experience our habitats at night, a variety of Halloween-themed activities throughout the Aquarium, a no-host bar, food available for purchase and more.
