Editing Danube (section)

== Geography ==
The upper Danube begins at [[Donaueschingen]] and flows east through southern Germany. It enters [[Austria]] near Passau, then crosses northern Austria before reaching [[Vienna]]. The river continues to [[Bratislava]], where it leaves the Alpine region and enters the Pannonian Basin.

The middle Danube flows through Hungary and passes [[Budapest]]. Farther south, it follows parts of the Croatian and Serbian borders before reaching [[Belgrade]]. It then turns east toward the Iron Gates, a gorge between the [[Carpathian Mountains|Southern Carpathians]] and the Balkan Mountains.

The lower Danube begins downstream of the Iron Gates. It forms much of the border between Bulgaria and [[Romania]], then turns north through eastern Romania before bending east toward the Black Sea. Near Tulcea, it divides into the branches of the Danube Delta.
