Flowing through France, Luxembourg and Germany the Moselle is the serene little sister of the Rhine. On an Avalon Moselle river cruise you can meander alongside quaint villages, picturesque vineyards and historic medieval castles. This 340-mile waterway rises in the dramatic Vosges Mountains of north-eastern France before curving gracefully into Luxembourg. En route it twists through some of Germany’s prettiest wine country and finally joins the Rhine at Koblenz. Winding between steeply contoured slopes, the river valley provides the perfect conditions for wine-cultivation. High, south-facing hills and slate soils ensure that young vines capture the most nutrients from the sun. The resulting fruits – crisp, floral Riesling, Elbling and Müller-Thurgau varieties amongst them - are admired the world over, while the vine-clad vistas provide a truly restful backdrop to a river cruise.
