We’ve free-camped pretty much every major city in Spain but the last and by far the most challenging city to drive around and free-camp was Barcelona.
Having spent a full afternoon driving around the city, beach and port to look for parking we decided that free-camping in the actual city is near to impossible.
We ended up finding a good place to park (for free) near the Olympic stadium on Montjuic park, right opposite the swimming pool. We stayed here for 3 nights and even left the van unattended for 24 hours whilst we stayed with a friend across the city.
This is about 2.5km from La Rambla and a short walk to the nearest Metro station, Espanya.
