PRELUDE: THE DANUBE AWAITS

You're in Regensburg. The Main-Danube Canal is behind you. Ahead: the Danube.

For the next 2,500+ km, this river is your highway. It flows southeast—through Austria's elegance, Slovakia's castles, Hungary's plains, Serbia's gorges, Romania's delta—until it empties into the Black Sea.

The current is strong (4-8 km/h). Finally, after weeks of locking upriver, the river is working with you.

Romans built forts along it. Ottomans besieged cities on it. In 1364, it froze solid.

Now: you.

River navigation tips:
