Scarium at the Aquarium 2026

Great Lakes Aquarium invites guests to their spookily-decorated aquarium to trick-or-treat among the exhibits and show off their creative costumes. The event features crafts, projects and games, as well as activity materials to take home and enjoy.

Great Lakes Aquarium proudly participates in the Teal Pumpkin Project. That means that no edible treats are provided during trick-or-treat.

Pre-registration is required for all parties, with times available on Oct. 27-29 between 4 p.m. and 7 p.m.

In order to allow time for event set up, Great Lakes Aquarium adjusts their hours for the event and is open to the public from 10:00 a.m. – 3:00 p.m. on October 27th, 28th, and 29th. The exhibit floor re-opens at 4:00 p.m. each day to accommodate pre-registered Scarium at the Aquarium guests.

Cost is $20 for adults, $16 for youth ages 13-17, and free for members or children 12 and younger.
