This story had to be mainly about the
cheap route of how to get from Krakow to Slovakia (and Banska Bystica in
particular), but due to some difficulties it turned into my personal
mini-adventure.
If you wonder how to get from Krakow to Slovakia, you
might find different options. Direct bus to Banska Bystrica for 200 zl. (almost
50 euros), via connection trains(one of them might lead you even to the boarder
of Czech Republic), via bus to Bratislava(service provided via Polskibus), via
Katowice (depends on your timetable), Lysa Polana and Chocholow.
