Better known as Parque de las 7 tetas (7 tits park) because the hills' shape, this green area is famouse because the great city views u can get from every hill. A ceramic factory and a dump where located there in the past, later restored into sports pitches (lower part) and those 7 hills.
Perfect spot to take some photos, read a book while enjoying a wonderful sunset, have a chat with your friends or couple, or just lie down on the grass while relishing of those wonderful views in a quiet environment. You can get there easily by metro (line 1, Buenos Aires《M》or 141 bus line from Atocha Renfe)
Fireworks show the first Sunday night after the 16th July (closing the El Carmen fair)
