When you look from outside it seems as if it’s just a normal cathedral, but when you walk inside you see a beautiful church. Very cheap entry and you are allowed to take pictures inside.
In addition to temporary exhibits, the Montreal Biodome features five permanent ecosystems. You should factor in two hours to explore the entire facility.
There are 6 distinct buildings housing exhibits. All are connected underground in case of bad weather.
The exhibits require much reading and are only available in English and French. You must reserve in advance. Tickets are available online.
If you don't want to climb the stairs, there is a shuttle bus taking visitors half way up the hill.
