Mirador d'Horta
This splendid observation deck overlooking Barcelona is located on the road from Cerdanyola to Horta, at kilometre post 9.5, on the southern side of the Collserola Ridge.
It opened in 1995. If you go there in the evening, when the sun is beginning to set in the west, you can enjoy beautiful, clear vistas of the city. Almost at your feet are the Velòdrom, the districts of Horta and Montbau and, in the distance, the sea.
