A guided tour, lasting approximately three hours, which begins in the Joan Brossa gardens and passes by the Alcalde viewpoint. This stroll along Montjuīc enters a wooded area that ends at the Camí del Mar path, passing along the entire coastal side of the mountain to the foot of the Montjuīc castle. Surrounded by a dense pine grove, this castle still preserves the tower, Torre del Guaita. The next stop is the Migdia park, which connects with the high plateau of Gurugú and the old path, Camí de l'Esparver, once home to an Iberian village. This was the first populated city centre and the location of many of the quarries that provided the materials necessary to build the streets and palaces of Medieval Barcelona. This activity will take place every Sunday.
