Passau sits on a peninsula so narrow that from the fortress above you can see three rivers meeting at once — the green Inn, the blue Danube and the black Ilz, each keeping its colour for a while after they join. Italian architects rebuilt the town in baroque after a 17th-century fire, so it feels less German than Mediterranean.
1. Veste Oberhaus terrace
Fortress above the town · Map ↗
The three-river view — the single best panorama on the Danube, and the reason to come.
2. The Ortspitze
Tip of the peninsula · Map ↗
Standing at the actual confluence, water on both sides. A very literal "our two lives becoming one" setting.
3. Residenzplatz & the baroque lanes
Old town · Map ↗
Pastel Italian baroque, wrought-iron signs and narrow shaded streets.
4. St Stephen's Cathedral
Old town · Map ↗
Home to one of the largest cathedral organs in the world, with daily recitals in season — an unusual soundtrack for a celebration.
The confluence as a metaphor
Photographers love the Ortspitze for the obvious reason: two different waters becoming one and continuing together. It is the most naturally symbolic setting on this entire list, and it costs nothing to walk out to.
Getting there and around
Passau is about three hours from Prague and thirty minutes from the Austrian border, which makes it an easy add-on to a Linz or Danube trip. The old town is small and entirely walkable; the fortress is reached by a shuttle bus, a road or a footpath.
Frequently asked questions
How far is Passau from Prague?
About 250 km, roughly three hours by car through the Bohemian Forest. It is also only half an hour from the Austrian border and 90 minutes from Linz.
Where is the best viewpoint in Passau?
The terrace of Veste Oberhaus, the fortress on the hill above the old town. It is the only place you see all three rivers meeting clearly.
Can you see the different river colours?
Often, yes — the Inn runs pale green with alpine sediment, the Danube blue-brown and the Ilz dark. The contrast is clearest in good light and after dry weather.
Is Passau good for a river cruise proposal?
It is a major Danube cruise port, and local boats run confluence trips in season. A short cruise at golden hour is one of the nicest ways to do it here.
