As the public transport is very good in Montreal, you don’t have to worry about getting around. The Metro will take you to all the main tourist attractions and is fast and efficient. There are relaxing boat rides along the river, which are a great way to see the sights.
The city also has 450 kilometres of bicycle paths, which makes cycling around the city very easy and pleasant. If you want to go a little further afield and explore more of Canada then you might want to consider hiring a car.
