Our 100,000-square foot bunker is the best place to enjoy some safe and physically distanced Halloween fun!

Come dressed in your favourite costume. Discover spooky (and cute) ghosts and monsters throughout the museum, and earn some treats (see details below).

The Diefenbunker offers plenty of open space to run around, and we will allow a maximum of 25 people per time slot. Over four floors and 100,000 square feet — that amounts to between 12 and 15 people per floor during your chosen time slot.


By donation for parents, grandparents, or caregivers with kids. You must reserve your tickets in advance. Walk-ins will not be accepted.
