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.

PART 1: UPPER DANUBE (Austria)

Navigation Overview - Austria

Distance: Regensburg to Vienna - ~350 km

Time: 5-7 days

Current: 4-6 km/h (downstream—fast!)

Character: Castles, vineyards, Baroque cities, Austrian precision

Locks: None (free-flowing river Austria/Slovakia)

Hazards: Strong current, bridge pilings, commercial traffic

River navigation tips:

Current is STRONG - Approach docks/marinas at angle, engine ready
Bridge pilings - Stay center-channel, avoid eddies near pilings
Commercial traffic - Cargo barges have right of way, stay clear
Anchoring - Find eddies behind islands/points (current less strong)
VHF - Monitor river traffic channels (varies by country)
