After Hours: Halloween

Date

Thursday, October 30, 2025

Time

7–10pm

Location

Seattle Aquarium

Join us for a graveyard splash!

After Hours: Halloween returns to the Ahhhhquarium for a night of fun, frights and aquatic delights.

Enjoy your chance to creep around our habitats at night and rattle your bones to music from DJ Asher St. Mars. Slink up to the café and sink your teeth into spooky snacks available for purchase.

We’ve got lots of frighteningly fun activities to send chills down your spine. Show off your drop-dead gorgeous looks in our costume contest. Watch expert pumpkin carver Russ Leno bring to life his gourd-geous creations. Take a trip to the other side with a tarot card reading.

After Hours is for adults 21 years old or older. View our After Hours FAQ for more information.

Please note: For the health and safety of our animals we use natural lighting as much as possible, so there may be limited visibility of some habitats. There’s nothing scarier than substandard animal care!
