I will be in austria taking a language course for like 28days. I want to visit the upper engandine (Sils Maria) in Switzerland and numerous places in germany ( freiburg, tubingen, weimar, leipzig maybe, munich etc). I will basically be in vienna though. I want to check out the austrian alps too though. So do I need a pass or should I just wing it? I would be traveling on the weekends (4).
