Events Description
Join us underground for a day of spooky season fun for all ages.
Free Halloween programming will take place at the museum entrance and in the Blast Tunnel. Stop by for activities for youth and families, a spooky photo backdrop, and trick-or-treating (while supplies last). No admission or booking is required to take part in the free programming.
We invite you to continue your Halloween visit inside the Diefenbunker with general admission — explore the museum and take part in a Halloween-themed scavenger hunt along the way.
