Very few people know that oil was produced in Collserola. In the middle of the last century, owners of farmhouses in this mountain range surrounding Barcelona owned olive trees, made self-consumption oil from them, and sold the surplus. But with the abandonment of the countryside throughout Catalonia, all this productive activity was also lost and the olive trees of Collserola, some centuries old, were swallowed by the forest. If in 1956 21.5% of Collserola were cultivated land, now it is only 6.4%. This not only represents a loss of the typical biodiversity of the area, but also has a dangerous collateral effect: it increases the risk of fire.

"For the locals it's great, but for businesses it's a load of rubbish. We are a tourist town, whether we like it or not, and if we don't let people come... I don't know what they will live on!" This is how Cisco, a resident of Cadaqués, sums up the new restrictions on access to Cap de Creus by car or motorbike. Since 11 June, you can only enter on foot, by bike or with the shuttle bus, about which there have already been many complaints about the service: the timetables are not clear and it costs 8 euros per adult. The town council admits that there are aspects that need to be improved, such as signposting, but they believe that the measure is essential to preserve the natural park and avoid images like those of last year, with peaks of 1,500 cars parked in every corner of the area.
