*Please note that the multiple levels, stairs, and narrow hallways in the Diefenbunker make the museum difficult to navigate with a stroller, and there is no elevator available for public use. While there is an accessible stair lift, we recommend bringing a baby carrier instead of a stroller, if this is a feasible option for you. Learn more about accessibility.
