The pretty town of Bernkastel lies in the heart of the Moselle wine region, and is known for its excellent dry whites based on the Riesling grape.

One of the prettiest towns in the Moselle valley, Cochem is a popular stop for river cruise ships. With an old town full of half-timbered houses and a castle perched on a hill it’s a quintessentially German scene, and the riverside promenade is lovely during the sunny summer months.

The Drosselgasse, a narrow cobbled lane flanked by old timber frame buildings, is particularly atmospheric.

Strasbourg is the capital of France’s Alsace region, right next to the border with Germany, and there is a tangible Germanic influence that sets the city a little apart from the rest of France.

Breisach is a small town on the western fringe of the Black Forest, separated from the French region of Alsace by a bend in the river Rhine. This proximity to France is reflected in a vibrant food and wine scene, and architectural highlights include the hilltop St Stephen's cathedral.
