My first time back to Montreal in 10 years and had to re-visit Old Montreal. It's one of those rare historic areas in Canada where you can pretend you are in the 1800's. From the cobblestone road to the Old Port to Notre Dame, there are plenty of historic buildings and structures to tour.
I loved walking on the Old Port as you get a great view of the St. Lawrence river and see some other attractions such as the Science Centre. In addition, there are plenty of benches.
Verdict: One of the must-visit sites in Montreal. Don't miss out.
