We had not been to Quebec City in 15 years, so a return trip was way overdue. We did it over Columbus Day 2016, adding Friday to make it a four-day weekend. That was enough time for a fun little expedition with plenty of sightseeing.
The Canadian dollar was worth about $0.75, so some things looked more expensive than they were. Overall it was easy to stay on budget. Gas is expensive there, but if you fill up in Fort Kent then you won't need to buy much or any gas until you get back over the border.
We spent Friday driving north through the length of Maine, departing I-95 at Sherman to take lonely Rte 11 past Mount Katahdin due north to Fort Kent, and then on to Riviere-du-Loup, Quebec, on the mighty Saint Lawrence. There was no foodie excellence that day, but we love that drive up Route 11 and the scenery was excellent. We spent the night at the Auberge de la Point in Riviere du Loup, a sprawling complex not far from the ferry terminal.
