Introduction to the Neckar River: The Neckar River originates from the Black Forest and is an important tributary of the Rhine River. The Neckar River runs through the city of Heidelberg, close to the old city. In the green mountains and river valleys, it complements the old bridge and the castle, forming a perfect picture. There are river banks for pedestrians on both sides of the river, especially the north bank, where there are lawns and gardens, making it a good place to relax and enjoy the scenery. If you want to get more immersed in the local life of Heidelberg, you can also go along the north bank to the large lawn west of the Theodor-Heuss Bridge. On holidays with nice weather, it is a favorite leisure place for Heidelberg residents.
