In reply to danm:
> Friends have reported from several locations (Margalef, Suirana, Albarracin) that police have visited climbers in vans, told them the crags are now closed and to self isolate for the next 15 days, but that driving to the border is OK. Those who got there on a UK-Spain ferry are reporting that they can't book an earlier ferry home online and that you can't get through on the phone. So it sounds like either sitting it out or taking a punt that France doesn't fully lock down and going for a long drive home.
My sister's down near Valencia and was told they would be taking registrations, and the vans weren't to move.
Presume you'll have questions to answer of you arrive at another Spanish vanlife site after the lockdown has started if your reg has been logged, but you'll be OK wherever you park up if you've not been clocked yet.
