We will be spending 3 days in Colmar this December, primarily visiting the Christmas markets. We arrive around noon on Thursday and will spend the rest of the day exploring the town. On Friday, we will be taking the train to Strasbourg for the day.
We're looking for suggestions for the third day. We don't have a car, so it will be local transportation. One idea we had was to visit Basel but were thinking about doing that on our way to Zurich. So, that leaves us with Saturday. We're open to any suggestions.
