An expansive urban woodland climbing the slopes of Collserola, west of Barcelona, this park unfolds amid dense Mediterranean vegetation. The Parc de l’Oreneta offers plans for those in search of calm or adventure alike: walking beneath pine trees, discovering the scent of aromatic herbs or climbing to the viewpoint to see how the city pushes through the green. And on Sundays, something special happens: the forest transforms into a small railway station, where a miniature steam train runs along tracks that seem lifted from another era. If there’s still energy to spare, zip lines and walkways invite you to move between the trees as though in an urban jungle.
