Not to be missed. The most interesting attraction in Ottawa area. 30-45 mins drive outside Ottowa. 50 $ Uber fare. 4 floors underground, very large complex, takes 2 hours to visit.

This place was very interesting. A great piece of history we hope never has to be repeated. The nostalgic pieces in each of the rooms were very interesting to see. Worth the drive if you are in Ottawa.

No cafeteria but lots of places to eat nearby. We took bottles of water and worked up an appetite by the end of the tour.
