Just before taking the Cable Car from Parc Montjuïc Stop, go to the left along Avinguda Miramar, with the Cable Car station behind you, until you reach the Plaza de Neptú. Then take the first street on the right, Passeig de Santa Madrona, and walk for about five minutes until you reach a crossroad. Then, continue straight along to the Montanyans Avenue until you see the Museum.
