Beautiful area, indeed. Liked so much the old buildings from the old centre and the stone bridge... And the ginger cat... And the flowers... and... No, no, forget all this, I liked your whole post!! :)
When you said Colmar, I checked in the map. So it is close to where we stayed, in Mulhouse, three years ago, and from there we passed the Rhine river and continued our travel in Germany. Now some desire hits me to do a similar route this summer, but, let's see how things go until then!!
Yeah Mulhouse is in the Alsace, just south of Colmar. It definitely has the same sort of vibe to it but is a larger city. An Alsace trip is definitely worth it if you like these sorts of towns.
Colmar - Kayserberg - Riquewihr - and Strasbourg are all amazing spots in the region. Eguisheim, Obernai and Chateau de Haut Koenigsbourg could be added in as well depending on time. You can see a lot of amazing destinations all in one small area and just a few days since all are so close together.
Anyway, that's in case you ever do go there.
I do like them and I wish we could do several days routing and visiting smaller towns there. Nothing is impossible, it's not that far away :)
Until then, your posts serve perfectly :D
