Drachenfels

The Drachenfels ("Dragon's Rock") near Königswinter is the most famous hill in the Siebengebirge range and one of the classic viewpoints on the Rhine. Its summit, about 321 m (1,053 ft) high, is crowned by the ruins of a medieval castle, with vineyards, the fairytale Schloss Drachenburg and sweeping river views below. Ride up on Germany's oldest cog railway or hike the old donkey path; either way it is one of the best day trips from Bonn or Cologne.

Where it is and how to get there

The Drachenfels rises above the small town of Königswinter on the east bank of the Rhine, roughly 10 km southeast of Bonn and about 40 km from Cologne. Regional trains on the right-bank Rhine line stop at Königswinter station, and light rail line 66 runs from Bonn's main station to Königswinter, so the trip is covered by the Deutschlandticket. From Cologne, plan on about an hour by train. A car ferry also links Königswinter with Bonn-Mehlem across the river. Drivers will find several parking lots near the valley station, but the railway operator advises following local signs, as roadworks can confuse GPS directions.

History and legends

The hill is an ancient volcanic dome of trachyte, a stone quarried here since Roman times and used in the Middle Ages for buildings including Cologne Cathedral. Quarrying threatened to destroy the hill, so in 1836 the Prussian state bought the quarry to save it, an early landmark of German nature conservation. The castle was begun after 1138 by Archbishop Arnold of Cologne and was razed in 1634 during the Thirty Years' War; the keep and part of the great hall survive.

Legend says this is where the hero Siegfried of the Nibelung saga slew the dragon and bathed in its blood. There is no historical proof, but the story, along with Lord Byron's 1816 verses in Childe Harold's Pilgrimage, made the Drachenfels a magnet for Romantic-era travelers. It is often called "the most climbed mountain in Europe," though no figures back that claim.

Things to do

• Summit plateau with a modern glass restaurant building, officially opened in 2013.

Is it worth visiting?

Yes, especially on a clear day. Allow 2 to 4 hours, including the castle ruins, a drink on the plateau and perhaps Schloss Drachenburg. Hikers can walk up the steep Eselsweg (Donkey Path) from Königswinter's riverside in about an hour; families often ride up and walk down. Spring and fall bring the best light and fewer crowds than summer weekends.
