how can I get a "konus card? Can the konus card be used at the places that I'm going?
my route is roughly
Day 1: Freiburg > Todtrau > Feldberg > Freiburg
Day 2: Freiburg cathedral > titisee > triberg
Day 3: Triberg > triberg waterfall > gengenbach
any advice for what buses/trains to take when going to these places?
