HallowMarine 2021

The Oklahoma Aquarium will host seven nights of trick-or-treating fun for all ages! Guests can follow the Trick-or-Treat trail for candy and see our fascinating marine life in the surrounding exhibits. Dress up in your best Halloween costume for a chance to win prizes, and join us for the opportunity to interact with some of the ocean’s most curious creatures from the deep!

This year’s event will include the same protocols to ensure the health and safety of our guests, vendors, staff, and volunteers. Safety measures include nightly admission caps, mask requirements, and glove requirements for vendors, in addition to our ongoing safety efforts.
