We just went to Montreal for 3 days. You can spend some time in Old Port and Old Montreal area and the Notre-Dame basilica which was beautiful. We also hiked up the Mont Royal and took the bus back in town. You can also go to Insectarium and Planetarium.

Jardin Nelson restaurant is a very good option with family in the Old Montreal (Jacques-Cartier Place) with live jazzz music.

Have fun!!

We'll be staying on a house on a lake near Mont Tremblant for a week and also spending four nights in Montreal. Any suggested activities? I assume we will be spending a lot of time at the lake house, but will probably head to town a few times. How is the splash park? Would a 3 year old like the gondola?

How about Montreal? Restaurants with good food that are family friendly?
