The route between Montreal and the eastern city of Halifax is arguably one of the most scenic, and definitely the most overlooked, of Canada's rail routes. This overnight trip follows the St. Lawrence River and passes through the eastern provinces of New Brunswick and Nova Scotia. Dubbed The Ocean, because it runs all the way to the Atlantic, this is arguably one of the most scenic lines in Canada, and provides visitors with an up-close look at the landscapes of the provinces of Quebec, Nova Scotia and New Brunswick.
