Parc del Nus de la Trinitat

It's an easy trip to this park using the red line (L1) on the metro (get off at Trinitat Vella). There is a huge, clean picnic area with barbecues, tables, benches, and a semicircular canal, a parade of poplar trees and olive trees in perfect formation, an impressive Roman frieze sculpture of 15 stampeding horses running in a meadow – 'Cavalls desbocats' ('Runaway horses'), by Josep Ros) – and more than 60 gardens that are cultivated by the retirees in the area.
