Circuit de Montjuïc

"This park is vast on and around Montjuïc, south of the city center. The small mountain overlooks the main Mediterranean terminals, with the 17th-century Castel de Montjuïc at its peak. It now houses a military museum that affords impressive views of the city and the water. Montjuïc Park is also home to several of Barcelona's top museums, including the Olympic Sports Museum (Museu Olímpic i de l'Esport Joan Antoni Samaranch), the Barcelona Ethnology Museum (Museu Etnològic de Barcelona), and the macabre but fascinating Museum of Funeral Carriages (Museu de carrosses fúnebres)."

"Montjuïc, meaning "Jewish Mountain" in medieval Latin and Catalan, is a hill overlooking Barcelona harbor. A great place for views on a clear day, you can also ride the Telefèric de Montjuïc cable car to/from Barceloneta beach. For more info visit - https://www.telefericdemontjuic.cat/en"

"There are some nice views from the various pathways outside the Palau Nacional de Montjuïc museum. If you arrive before sunset then you can appreciate some lovely views of the city from this area."
