Another great option is to take a late train to the park in the North-West of Barcelona. For example, you can take the S2 to ''Sabadell'' (ticket zone 1) leaving from ''Placa de Catalunya'' and getting off at ''Beixador de Vallvidrera'': there is a big park which is nearly like a forest, and you will find a very good and lonesome place to stay within 500 meters from the station.
You can also take the metro from "Placa de Catalunya" to "Canyelles" station, walk about 200 yards uphill from the station and find some nice hills to camp/sleep out/hang a hammock in.
