Take the A44 motorway to the "Südkreuz Kassel" junction. From there, take the A49 in the direction of "Kassel-Innenstadt". Leave the motorway at the "Kassel-Niederzwehren" junction and follow "Frankfurter Straße" into the city. 500 metres after the Jet petrol station, turn left into "Altenbaunaer Straße". Cross the tram tracks twice as you proceed. Then turn half right into "Oberzwehrener Straße".
