Avinguda de la Reina Maria Cristina leads from Plaça d’Espanya towards Montjuïc. On the hill ahead of you is the Palau Nacional de Montjuïc, and stretching up a series of terraces below it are Montjuïc’s fountains, starting with the biggest, La Font Màgica, which comes alive with a 15-minute lights, water and music show repeated several times per evening.
