Weltenburger Enge and Danube Gorge National Natural Monument

The "Weltenburger Enge" is also one of the "100 most beautiful geotopes in Bavaria" selected by the Bavarian State Office for the Environment.

150 million years ago, a shallow, subtropical sea covered the Kelheim area. Corals and sponges built up mighty reefs from limestone - today's rock faces of the Weltenburger Enge. Around 200,000 years ago, a tributary of the Urdonau dug its way through the limestone, creating the present-day riverbed of the Danube. Over a distance of around five kilometers, the river flows between the limestone cliffs that rise up to 70 meters: an impressive sight that is best enjoyed from a ship or boat.
