Part 3 of the famous German castle road. A really beautiful and quiet route which follows the river Neckar, drives in Bavaria forest and runs through lot of castles. Awesome scenery and not traffic at all. The complete roads goes like this: Heidelberg - B37 - B27 - Heilbronn - B39 - L1035 - L1036 - Langenburg (great castle)- Rothenburg (another one great castle) - B13 - Ansbach - B14 - Nornberg
Note: there are lot smaller castles around the route
