The hills are easy walking. The whole island reminded us of Bar Harbor, Maine and Gloucester, Massachusetts. Most of the shops were closed as we arrived on a Sunday. There were tents of food and crafts to purchase. Similar to "farmer's markets" in the US.
Glad we beat the lines and got the first 10:00 canal tour. Started to rain for the whole day after we got off. Fortunately, we our foul weather rain gear. The city itself was quaint. Bring lots of Euros and many shops do not take MC and.or VISA.
