Backpacken through España!! Español

Holaaa everybody,

From 13 july - 22 july I am going to backpack through Spain!
I will go on my own and I am very excited.
Has anyone some tips for me? Something I cannot miss when I am in Spain.
I hope for some great suggestions!
And maybe I will see you there haha.

Adíos!

Good luck,

I don't know whether you will be hitchhiking but if you consider it I found this to be the most useful related website: http://hitchwiki.org/

Have fun!
