Situated along one of Germany's most scenic river valleys between the Rhine and the Moselle river, Koblenz is a striking city with a glamour of its own. The Upper Middle Rhine Valley, extending for 65 kilometers from here to Bingen, was assigned the tag of UNESCO World Heritage Site because of the region's natural beauty along with its cultural and historical significance. It is one of Germany's oldest settlements that dates back at least two thousand years. The medieval castles, lush green vineyards, historic sites, waterfront promenades and rolling hills here will awe you. The views from the Ehrenbreitstein Fortress overlooking the confluence of the two rivers and the city are unmissable
