This is the right place to begin with !

This place is amazing if you need information about what's to do in Montreal and Quebec. You can purchase tours and packages to New York City and Niagara Falls. There's a gift shop, a convenience store, public restroom, free 15 mins. parking (very convenient !) and there's a counter (Tourbec) where they do hotel bookings and packages to Quebec City, Tadoussac, NYC, Manhattan and Toronto. It's a bit crowdy and noisy during peek summer, but evething is very useful. 2 thumbs up !!!
