This is less of a hike and more of a guided walking tour of Xanten. The goal here is to get all of the interesting viewpoints of the city. Of particular interest are the long-distance panorama views, I find the image of the cathedral rising above the plains to be a rather romantic image. This will help you find the shots that might be missed otherwise.

Deep in the Westerwald sits the great castle of the Solms family. Better described as a palace, it represents the 19th century ambitions of the Solms family. This hike is all about trying to get the best views of the castle.

This photo tour can be something of a hike, but it offers many of the most famous viewpoints in the Middle-Rhine. The first famous scene is of Kaub with its two castles from the opposite side of the river. Then there is the panorama over Bacharach with its medieval spires and its dramatic vineyards.

This is less of a hike and more of a photo-tour to one of the most fantastic parts of the Middle-Rhine. In particular, the picture of the Castle Katz overlooking the cliffs of the Loreley is among the most iconic in Germany. To see this view for yourself, as well as several others, you can simply follow the path here.

This hike is for photographers interested in the most spectacular views of the Trifels castle. For centuries, it protected the crown jewels of an Empire and its dungeons held prominent guests such as King Richard the Lionheart.
