Col de Saverne

The Col de Saverne is a natural pass in the north of the Vosges mountains, near Saverne, which permits travel between the départements of Bas-Rhin and Moselle, and therefore between Alsace and Lorraine.

Transport routes that traverse the Saverne Pass include national highway RN 4 and A4 autoroute A4, the Paris-Strasbourg railway, as well as the Marne-Rhine Canal.The area is noted for its botanical gardens, especially the Jardin Botanique de Saverne and the Roseraie de Saverne.

The Saverne Gap is a gorgelike passage that cuts through the Vosges from Arzviller to Saverne, following the course of the Zorn River for most of its length. The passage is barely 100 yards wide at some points.
