In the summer, France is my goal. One month, maybe more. I'm sixteen, from the EU, so how much can I expect to spend?
Let us take into account that I'm going to try to save as much as possible - ie, free camping(not at campsites except occasionally), hitchhiking, CouchSurfing and HospitalityClub as much as possible. Eating at supermarkets, that sort of jazz. Because I really don't want to put a dent in my parents' bank accounts, but I also can't really get work here in my country, especially seeing as the economy is taking a big shit-dive and already measly wages are getting cut by, oh, 10%.
I want to go most to Languedoc-Rousillon, perhaps detour into Spain to go to Barselona. So - south of France mostly. Oh, and I want to work on a organic farm for a week or two(WWOOF), but I will have to find out whether they take under-18's.
Thanks. :)

If you're hitchhiking, camping and couchsurfing you can do this very cheap indeed. Somedays you might not spend anything, but I'd budget at least ten or fifteen euros a day plus a couple hundred in case of unforeseen circumstances, which there always are..

Wwoof I believe very rarely takes under 18s. Depends on the country, I think.

Have fun!
