be safe
Heidelberg is an extremely safe city even by German standards. However, women walking alone at night should take the usual precautions they would do anywhere else. Walking along the northern Neckar banks at night would not be advised, except in groups, particularly by the Studentenwohnheime dorms. The shrubs are thick and it is very dark.
Usually there won't be any problem. If you are a bit 'paranoid' you can take a Taxi. If you are from New York, you might think they are cheap - if you are from East-Europe or Asia you will feel like they are ripping you off... use as needed. There are also "Frauentickets" available for women, you can buy these coupons for 8⬠and they will cover the fare for anywhere in the city.
Don't walk on bicycle lanes! - Really don't! they are often painted in red, but always separated from the pedestrian lanes by a white line: Heidelberg has more cyclists than motorists, and many of them have a rather cavalier way of riding. The southern parallel street to Hauptstrasse called Plöck is the main traffic channel for student cyclists between Bismarkplatz and University Square. During the day it can be such a buzz, it's already a sight worth visiting. But watch out: Many cyclists feel safe from the tourists there and lose all their good manners.
