About Colmar

Colmar's Little Venice quarter, the Unterlinden museum and the Isenheim altarpiece fill a compact old town, with the Pfister house and the market square anchoring the lanes. The Alsace wine route runs south through Eguisheim and Riquewihr, and the Christmas markets turn the town into one of Europe's best-known Advent destinations. May to October is best for vineyards and villages; summer is busiest, and harvest fills the cellars.
