In Hungary the Danube has become a lowland rather than a mountain river, as it crosses the flat Hungarian plain. A brief exception is this crossing of the Börszöny Mountains between Nagymaros and Visegrád, an area with beautiful scenery as the Duna river makes an S-curve in front of the royal fortress at Visegrád.
