So yes, walk up and down Place Jacques Cartier, as this is pretty much the touristy hub of Montreal but also adorable and joyful in brief tastes if you're local. The narrow cobblestone alleys that lead off the pedestrian square are pretty and tucked with the usual tshirts and maple candy, their real virtue in them is in leading to the further stretches of the Old Port where there are art galleries and better restaurants and boutiques with higher end designers. \n\nIf you walk along the water towards the west you can see the giant old grain storage and the speakers on the shore that let you hear your voice echo around the empty old icons of industry. Eat a lobster roll, check out the crazy architecture across the water from back when Montreal was a 60s stoner dream of what the future would look like. \n\nI suggest starting from Champ de Mars Metro and then Walking up McGill to Square Victoria but anyway you do it just get lost in there, have some wine and cheese, have fun.
