We weren’t really sure what to expect, but we weren’t disappointed!!! We decided to go on the guided tour, with Graham being our guide. He was really knowledgable but also quite funny. The tour took approx 1.5 hours with the opportunity to look at a few exhibits but I’m not really sure that it was necessary as Graham covered a lot of ground, we were free to have a look around outside on our own - there was a small walking trail. Positives: All of it !! Negatives : none really - except a bit more signage to the entrance as you have to walk up the tunnel, and turn right to the ticket office.

A brilliant 1 1/2 hour trip back in time to an era that seems like a nightmare in these modern times. Our guide, Graham, was informaive and funny and kept us going through the complex with anecdotes that really made the history come alive. Well worth the visit.

Make the detour from Ottawa city center, it is worth it! And plan your visit with a guided tour! Our guide immersed our group into the past with the perfect blend of humor, history, and seriousness. An unforgettable experience.

Awesome, and well worth your time to visit. Make sure you sign up for the guided tour. It's fasinating to see how Canada prepared for the nuclear war in the 1960's. And how preserved things still are today.

The guided tour is really great, my girlfriend, my 2 children (7 and 11 years old) and I really enjoyed the visit. It's informative and very impressive to visit as a place. Well done to all the people who work there, you are awesome and cool!

The tour guide (Brian) was amazing. He made the history of the bunker entertaining and captivating. He has written a book as well, it is available in the gift shop ( we purchased it). The bunker is an interesting place with amazing history. It is massive, with relics and day-to-day elements placed throughout the structure. I would recommend visiting this place with kids (or adults) of all ages!

I went with a Meetup Group on the guided tour. Our tour guide, Graham, was fun and entertaining. TBH, I wasn't expecting to like this much. I went because the group was going, not because I was particularly interested. It was really, really cool, and I am going to have to go back. The 2 hours was not enough to see it all.

On our visit to Ottawa we were so pleased with many of the local museums in the city. One that was an absolute standout, located 30 minutes west of Ottawa in Carp is the Diefenbunker Cold War Museum. So much information about how Canada prepared for Nuclear attack with rooms filled with furniture taking you back in time. This is an absolute must on a visit to the area. If you take the tour (which I strongly suggest) hopefully you will get the wonderful volunteer, Brian, who is quick witted and full of incredible knowledge of this time in history.

The Diefenbunker, how they built it, and the history behind it are really amazing. After the tour ended I did not want to leave. It is a really compelling story. We had a guide named Brian Jeffries and he was fun and informative. If your in Carp do not miss this tour, its very interesting.

Very interesting, worth the visit. We purchased tickets for the guided tour and our guide, Graham, was fantastic. Had lots of stories and history to share. Great museum for all ages, but parents really need to be mindful to keep an eye on their kids so that everyone can enjoy the experience.
