The Mosel River winds through peaceful countryside in Germany, Luxembourg and France. Sailings of the Mosel -- or the Moselle, as it's known in France -- are often combined with cruises of the Rhine River.

These sailings are easy to budget as so much is included in Emerald's price -- accommodations, many meals and beverages and shore excursions. At each stop, sightseeing guides share intriguing stories about local history and culture.
