This Halloween, the Georgia Aquarium will transform once again into Georgia A-Scary-Um. The event will kick off with a special sleepover on Oct. 30. This new treat includes sleeping in one of our monstrous exhibits, Ocean Voyager, while learning about aquatic folklore. On Halloween, children 12 and younger in costume will receive free admission. Family activities include arts and crafts, trick or treating, costume contests and giveaways.
