What is the cheapest way to go surfing in Europe?
It's probably best if you avoid France. Food is quite expensive compared to the other countries.
I'd suggest Nothern Spain or Southern Spain (even cheaper) if you go during surfing season. Portugal is also really cheap and even more laid back when it comes to wild camping etc.
Also, it might make sense for you to go to one of the hundreds of surf camps for a week. Sometimes you can even get board rental, accommodation in nice tipee tents and full board for around 200€/week and person. If you need help picking the right camp for you, feel free to hit us up anytime.
