He started from Vienna, where he ended some years ago his Via-Alpina, and is now heading to Bratislava, before entering Carpathian territory further north. His goal is nothing else than... Niš, in Serbia, by the end of the high season !
It's worth mention he consulted numerous useful SP pages to prepare his trip... Their authors will probably recognize themselves
We can follow his progress on his site :
