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. Watch expert pumpkin carver Russ Leno bring to life his gourd-geous creations. Gain insight into your past, present and future with our fortune tellers and aura readers. Join us for Ghost Stories of Puget Sound in the Underwater Dome for spine-tingling tales of local mysteries.

Show off your drop-dead gorgeous looks in our costume contest. Choose a category to make a splash in: Under the sea, end of the world or fantasy forever!

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!
