More than 20 years ago, the small, adventurous fish Bernhard discovered the Black Forest capital of Freiburg im Breisgau and its little streams. Bernhard's grandchildren, the sweet little goldfish Lea and Philipp, have heard so much about Freiburg from their grandfather. One day, their curiosity becomes too much to bear, and they make a decision: We want to go to Freiburg! Today, on a beautiful sunny day, they take the leap from their pond over the wall into the streams. They dive into a new, fascinating world and follow the course of the streams through the winding streets of Freiburg's old town. A picture book and city guide for children and anyone who can still marvel!.
