Passau is a nice little city at the border between Bavaria (Germany) and Austria and is called the “3 rivers town”: the main river is the Danube (or Donau), crossed by the Inn and the Ilz rivers
That location, on 3 rivers and on the country border gives this city all his character and interest. It’s a roman city foundation, and all along the past history, this city played an important role in many different situations. When you come into the city (by highway it’s the A3 from Regensburg to Linz), follow the signs to the old city and park there. Then (and that’s the great pleasure) just go into the narrow streets of the old city and discover it.
You can follow the signs to the Stephansdom (or St Stephen’s cathedral), beautiful “baroque” church built in 1688 which is really worth the visit! Then go north in direction of the majestic Danube river and walk along direction east. After a while, you’ll come to the intersection with the Inn river and you can walk way west along this other beautiful “riverscape”. If the sun is shining you have a lot of different colors in this city, and the light of the river is great too. A perfect place to walk and take pictures! :)
