The view of the Drachenfels is one thing, but the whole section is beautiful. A little bit of '50s excursion muff - which is meanwhile also iconic. Then there is the Petersberg to see and also Castle Drachenburg. Recommended.
The building is a replica, I believe from the 19th century, but it is worth a visit from outside and inside. The day before the castle was closed because of shooting, but fortunately we had seen it on the web page. As: before check if open!
