Bonnevoie, one of the largest neighborhoods in the capital city, also called Luxembourg, stretches from the area south of the main train station to the old city. From the northern section, you can follow the Alzette River past abandoned factories (that they’re supposedly turning into beach clubs one day), under the bridge that takes the train to Germany, and end up in the Ville Basse (lower part of the city center). From there, you can climb ancient staircases to the connection with the Ville Haute (the upper part of the city center).
