Passau

Three rivers, one old town, and a clear beginning to the Danube route.

Information about Passau

Passau is one of the Danube’s best natural route lessons. Three rivers meet here: the Danube, Inn, and Ilz. That geography explains the city before any sightseeing begins. Water brought trade, power, flood risk, architecture, and movement into one tight old town.

The city works well at the beginning or end of a Danube river cruise because it gives the journey a visible hinge. You can stand near the confluence, compare water colours and river widths, then walk into streets shaped by bishops, merchants, bridges, and river traffic.

Passau is pretty, but that is not the main point. The useful question is why it exists here. The answer is the water: three routes meeting in one place, with the Danube continuing east toward Austria and beyond.

Interesting facts about Passau

Passau is known as the “City of Three Rivers” because the Danube, Inn, and Ilz meet here.

The confluence is one of the clearest places on the Danube to understand river geography by simply looking at the water.

The old town sits on a narrow peninsula, which makes the river setting visible from many streets.

Passau’s position has long made it a gateway between Bavaria, Austria, and the wider Danube route.

Veste Oberhaus

Veste Oberhaus gives Passau height and context. From above the old town, the three-river geography becomes easier to understand: Danube, Inn, and Ilz meeting below, with streets and bridges squeezed between water and hills.

The fortress also shows the political side of river cities. Passau was not only pretty or convenient. It was a place to control, defend, tax, and watch.

For a Danube route, Veste Oberhaus is useful because it turns the confluence into a full picture. You see why the city grew here and why the river made it matter.

Dreiflüsseeck

Dreiflüsseeck is the point in Passau where the city’s geography becomes visible. The Danube, Inn, and Ilz meet here, making the old town feel like a peninsula between routes rather than just a pretty Bavarian centre.

This is a simple but important stop. Stand at the confluence and the map becomes physical: three rivers, different colours and volumes, one city built around movement.

For a Danube journey, Dreiflüsseeck is a clean beginning or ending. It explains why Passau matters before the route continues toward Austria and the wider Danube.
