The Loreley is a popular destination on the Rhine and attracts numerous visitors to the Middle Rhine every year. Especially the view from the 132 meter high famous slate rock on St. Goarshausen with castle Katz and St. Goar with castle Rheinfels is worth a trip. No wonder, then, that the valley was designated a World Heritage Valley by UNESCO in 2002. Since the Rhine at the Loreley is only 113 meters wide but up to 25 meters deep, this spot is considered one of the most dangerous in the Upper Middle Rhine Valley. The Loreley is also known for the romantic ballad by the poet Clemens Brentano.
