I'm getting lots of questions from potential GR1 hikers about wild camping in Spain. I've tried to answer as best as I can but because I haven't done any wild camping I can't claim to be an expert. Having explored various forums it's clear that most English hikers are confused about the legal status so I decided to do the thing I should have done in the first place and ask a Spaniard.
Juan Holgado is not, of course, any Spaniard, but an expert on all things to do with walking in Spain. I met him by chance on the third day of my trip from Tarifa to Budapest and since then he has become my Spanish walking mentor. He provided invaluable input into my Cicerone GR1 guide
and his website is a go to place for anyone planning a walking trip in Spain.
