From Old Town

There are three different ways to reach Cable Car from Dubrovnik Old Town First and second is from Pile or Ploče gates, and it takes approximately 8-12 minutes of walk around/behind city walls. There are pedestrian sidewalks from Ploče or Pile gates to lower station, path is not very steep and just with a few stairs, so it is quite easy to walk towards Cable Car.
Third and a bit quicker way, approximately 6-9 minutes, is by walking up the stairs from Stradun (towards Buža gate), and from there it takes just minute of walk across parking lot towards stairs below cable car, but it has a lot of pretty steep stairs and is intended for people in good shape.
