Located to the Southwest of the City Centre, Montjuïc is a broad shallow hill with a relatively flat top overlooking the harbour. The eastern side of the hill is almost a sheer cliff, giving it a commanding view over the city's harbour immediately below.

The views of the city from Montjuic are a must for a Barcelona visit.
