Beilstein is a tiny town sitting along the peaceful Moselle River (a.k.a. Mosel River in English). Beginning in France, the Moselle River enters Germany near Trier and meanders to Koblenz where it flows into the mighty Rhine River. While not nearly as popular as the Rhine Valley, the Moselle River Valley is a delightful place to visit as both sides of the river are dotted with castles, vineyards, and cute little villages.
