From the centre of Basle take the main road out of town to the south-west, following the directions either via Binningen > Bottmingen > Therwil or via Oberwil > Biel-Benken and then to Witterswil. Alternatively use the motorway link (J 18) and exit at Reinach South or Aesch.
By public transport (tram)
Take a No. 10 tram (from the SBB railway station or elsewhere in the city centre) in the direction of Flüh/Rodersdorf. From the tram stop in Witterswil it is only 5-7 minutes’ walk (north on the Biel-Benken road) to the TZW Technology Center.
