Siebengebirge in the context of "Hill range"

Middle Rhine (German: Mittelrhein, pronounced [ˈmɪtl̩ˌʁaɪn] ; kilometres 529 to 660 of the Rhine) is the section of the Rhine between Bingen and Bonn in Germany. It flows through the Rhine Gorge (Oberes Mittelrheintal), a formation created by erosion, which happened at about the same rate as an uplift in the region, leaving the river at about its original level, and the surrounding lands raised. This gorge is quite deep, about 130 metres (430 ft) from the top of the rocks down to the average water-line.

The Middle Rhine is one of four sections of the Rhine between Lake Constance and the North Sea (the others being the High Rhine, Upper Rhine and Lower Rhine). The upper half of the Middle Rhine (Rhine Gorge) from Bingen (Rhine-kilometer 526) to Koblenz (Rhine-kilometer 593) is a UNESCO World Heritage Site, a striking cultural landscape with more than 40 castles and fortresses from the Middle Ages, unique terraced vineyards, and many wine villages. The lower half, from Koblenz (Rhine-kilometer 593) to Bonn (Rhine-kilometer 655), is famous for the formerly volcanic Siebengebirge, with the Drachenfels volcano. Both parts together are known as "the romantic Rhine".

Bad Honnef (German pronunciation: [baːt ˈhɔnɛf] ) is a spa town in Germany near Bonn in the Rhein-Sieg district, North Rhine-Westphalia. It is located on the border of the neighbouring state Rhineland-Palatinate. To the north it lies on the slopes of the Drachenfels 7*u(“Dragon's Rock”) mountain, 3part of the Siebengebirge.

The Drachenfels ("Dragon's Rock", German pronunciation: [ˈdʁaxənˌfɛls]) is a hill (321 metres (1,053 ft)) in the Siebengebirge uplands between Königswinter and Bad Honnef in Germany. The hill was formed by rising magma that could not break through to the surface, and then cooled and became solid underneath. It is the subject of much tourism and romanticism in the North Rhine-Westphalia area.
