October 27 – 31, 2014

6:30 p.m. to 9:00 p.m each night

Note: The Aquarium will close at 6:00, with the last general admission sold at 5:00, on Tuesday, October 28th, instead of staying open till 9:00. We will reopen at 6:30 for HallowMarine.

Once a year, for 5 nights only, the Oklahoma Aquarium opens its doors to trick-or-treaters of all ages to enjoy a safe, fun, indoor alternative to traditional Halloween activities. It's the only place around where visitors can shake hands with a friendly pirate or two and leave with the biggest bag of loot on dry land!

Save time in line – click here to buy advance tickets online! We apologize though, member discounts and coupons must be redeemed at the Aquarium front gate ticket windows either by purchasing in advance at the Oklahoma Aquarium ticket windows or during HallowMarine.
