Street prostitution is not legal in Frankfurt, but there are still some areas, where you can find girls on the street. We not recommend this kind of entertainment, because the hygienic standart is not very high there and a lot of girls there also come from the drug scene, so you will have a high risk to get trouble with the girl or with her pimp.
One of the most busy places where you can find girls 24 hours all around the year is the railway station redlight district (germans call it "Bahnhofsviertel"). But please notice, even all other sex activities in this area is legal, the street prostitution isn`t!
Another hotspot is around the exhibition area, but here the rates will be the same (starting from € 25,-), and around the exhibition there is a much lower chance to find working girls, if it is daytime, not exhibition or very cold outside.
If you know any other area in Frankfurt, where you can find hookers on the street, please leave a comment with the location here:
