I have the link to this forum from a friend from Serbia, he said there are many bikers from whole balkans. and i will find there information and help. So I Apologize.
I have written to my friend who will make this trip that he should visit Serbia too. And he consider now a route from Hungary to Serbia, and than to Bośnia i Hercegovina.
Dakle, dati nešto bilo dobra mjesta u Srbiji, a kolega iz Mađarske će putovati u Srbiju, a zatim u Bosnu.
