If you have a bit of extra time then you really should pay a visit to the enormous cemetery on the north-west slope of Mont-Royal.
Spanning 165 acres, it was first opened in 1852. It's particularly fascinating to see some of the older tombstones, as well as the more ornate ones.
Walking through the cemetery is like walking through the history of Canada, with several famous people buried here.
Located at 1297 Chemin de la Forêt, Outremont, Québec H2V 2P9. On a hot day like the day we visited, the hike up to the cemetery gave us a work out. We entered through the rear entrance as this was easier to get to for us taking the metro. Exiting the Édouard-Montpetit metro station easier than exiting the Université-de-Montréal metro station.
Montréal has some beautiful cementeries. One of those -actually two- is at Mont Royal... pretty diferent to the ones we have where I live. Anyway, they say these are places that often host ghosts; I don't know as I couldn't see any, but... wait! look at the floor! Fallen leaves left their shadow impression on the ground, and still remain there after they're gone... like if they were ghosts! :)
I don't know how popular a place this is amongst tourists, but it is a rather pleasant place to visit on a warm, sunny summer day: the cemetary behind Universite de Montreal.
It is Quebec's largest cemetary and has several entrances. Get off at metro stop Edouard-Mont Petit and hike up the hill to the university and into the cemetery. It is well kept and houses many nice plants, trees and flowers. There are three sections, each for those buried that are of the Catholic, Protestant or Jewish faith. Some very prominent families are buried here, including the Molson's. Walking along you will reach the peak of Mount Royal that is more touristy and gives a great view onto the city.(the Belvedere)
