Hallowmarine @ Oklahoma Aquarium

The Oklahoma Aquarium is excited to celebrate our 19th annual HallowMarine this year. This fantastic, week-long indoor trick-or-treating event is fun for all ages. HallowMarine attracts thousands of families from the Tulsa metro area.

Each evening from 6:30 p.m. – 9:00 p.m. our guests trick-or-treat at sponsor tables throughout the aquarium. Kicking off on October 25th & running through the 31st, we see around 7,000 guests.

We invite you to be a part of this fun community event & partner with us for HallowMarine 2022!

As a 501(c)(3) nonprofit, all money collected by the Oklahoma Aquarium Foundation through sponsorships, and events go directly to our animal care, exhibits, and education programs.


Indoor Trick-or-Treat Trail: All exhibits remain open and guests can meet all 10,000 of our amazing animals, from the cute to the creepy.

Costume Contest: Contestants post a picture of themselves in costume at the aquarium & tag it with #HallowMarine2022. Judges review on November 1 & pick their favorites from the week. Winners receive free admission to the aquarium & a HallowMarine 2022 tee.

OKAQ Bounce House: Our aquatic-themed 20′ bounce house will welcome our young guests when they enter the OKAQ Great Hall. Featuring a slide, an obstacle course & more, it’s free for guests.

Booth Contest: You’re encouraged to decorate your booth with a Halloween or company theme. Guests will vote on their favorite booth & winners receive a unique trophy & special mention in our November newsletter & on-site.
