Rodderberg

About

The Rodderberg is an extinct volcano in the east of the municipality of Wachtberg near Bonn, Germany. The last eruption was 250,000 years ago. It is situated just above the Rhine valley. Together with the Drachenfels directly opposite, the Rodderberg narrows the Rhine valley. This gorge portion is the southern limit of the lowland-bay of Cologne. The Rodderberg offers views to the Siebengebirge, the Rhine valley and up to the Cologne Cathedral, about 50 km away.
