What Travellers Say
Reviews Summary
Visitors consistently praise the Diefenbunker as a fascinating and unique historical site, often describing it as a 'frozen time capsule.' The guided tours are highly recommended for their insightful content, bringing the Cold War era to life. While the underground nature and stair-only access to lower levels present some accessibility challenges, the overall experience is considered a must-see in the Ottawa region.
"This is one of the coolest places to explore in Canada. Visiting feels like stepping into a frozen time capsule. The atmosphere is very retro, with bright colours on the cabinets and flooring that create a cheerful vibe. The history behind the place is fascinating. We spent about two hours exploring all four levels on a self-guided tour. This was my second visit, and I enjoyed it just as much as the first time.
The first (top) level is accessible, but we couldn’t take the stroller any further since there are no elevators. Moving between levels requires stairs."

"This is a great activity. An amazing piece of Canadian history. More than a museum considering the facility was actually in service up until early 1990s.
It is a huge complex and there lots to see, and get lost. I would recommend a guided tour, but planning enough time before or after to roam around on your own too."
Stéphane Lavallée
"Absolutely awesome tour! The bunker is in a time warp and the guided tour was extremely insightful on how soldiers and high command dignitaries as well as commanders operated in the bunker. The technology of running air and water systems was out of this world for the era of time. I would highly recommend the tour and a must see when visiting the Ottawa region! 10 stars if I could give it!"
