Vallvidrera (Catalan pronunciation: [ˌbaʎβiˈðɾeɾə]) is a neighbourhood of the Sarrià-Sant Gervasi district of Barcelona, Spain.
It is situated in one of the sides of the Collserola hills, considered to be the lungs of the city due to the abundant forests it has.
This wealthy neighbourhood has excellent views of the whole city, from some specific places and in a clear day it is possible to see Mallorca and the Pyrenees on the horizon.
Although being a residential place it has important things such as, the Torre de Collserola (a communications tower designed by the architect Norman Foster), the Tibidabo Amusement Park and the Temple Expiatori del Sagrat Cor.
The neighborhood is also served by minibus line 111, which connects to the upper station of the Vallvidrera funicular and the top of the Tibidabo hill.
