We set off from Garraf train station and headed into the Massís de Garraf natural park, towards la Morella. We followed GR-92 up Serra dels Pins, gradually making our way to la Morella. The route alternated between walking on forest paths, gravel roads and asphalt. From la Morella we enjoyed the view of Montserrat, Collserola and the contaminated city of Barcelona. For the route back, we followed the forest path down to Castelldefels.
