Adventure

 

In the Valley of the Unknown

Adventure is like nothing else. Dark, foreboding, and elusive, Adventure: In The Valley of the Unknown is an entirely self-contained, mysterious world inside COSI. Step inside and you are transported to another place and another time: a remote island, shrouded in darkness, where remnants of an ancient culture guard a secret that only you can unlock.

Adventure requires the purchase of an extra timed ticket.
