This is simply a great view of the Siegtal. And especially for railway fans when a red S-Bahn or a red RE9 passes through. By the way, a photo of this view can also be seen in the Wikipedia article about the Cologne S-Bahn: https://de.wikipedia.org/wiki/S-Bahn_K%C3%B6ln

Impressive castle complex, especially when you first saw it from the valley. Unfortunately not always accessible.

A little below the Plateau you will pass this vantage point of Drachenburg Castle on the way. The view of the (almost kitschy) castle with the Rhine and the Bonn skyline in the background is great. Photos from the small platform almost automatically have postcard quality.

The model shows it at its best, around 1300. You can see here that the castle complex consisted of four parts, namely the main castle, the outer castle, the old town and the new town. It is one of the largest castle complexes in western Germany.
