From the medieval village of Turckheim (where you can meet the last night watchman/town crier in France) to the pretty old town of Obernai, you can see a succession of villages: Niedermorschwihr, Ammerschwihr, Kaysersberg (here you can visit the castle overlooking the Alsace plains and feast your eyes on all sorts of ancient relics), Riquewihr (a fortified town of the middle ages with double ramparts which are beautifully preserved, and date from the end of the 13th century and the beginning of the 16th century), Ribeauvillé, and Ottrott. From here you climb up on to the plateau of the Mont Sainte-Odile (an ancient monastery proudly perched at 763 m on a rocky pinnacle).
You can also visit the ancient fortresses of Hagueneck (400m), Hohlandsburg (645m), Haut-Kœnigsbourg (710m first built in the 12th century), Saint-Ulrich (standing over the village of Ribeauvillé) and Ortenbourg...
