 Bus route 400 (served by Arriva) has two stops along the western edge of the town, and takes the passenger either to Leiden in the north or Zoetermeer in the south.Prior to 2015, the 400 was numbered 365 and made an hourly ride through to the town itself.When Ariva was planning to scrap the route in 2013 (which was inherited from Connexxion which served Zoeterwoude-Dorp previously with their now defunct route 32), inhabitants protested and Arriva eventually caved.
