My head is kind of spinning from looking into busses from Salzburg. Within the city itself I think I will mainly walk, but know I can buy a local bus ticket if needed. This seems straightforward enough. However I will be in Salzburg for a few days in early June and if the weather is pleasant I'd like to head out to a nearby mountain/natural area for some light hiking. Just spend half a day or so enjoying nature.
So my research has shown that Untersberg and Gaisberg are recommended nearby places, accessible by bus from Salzburg. I even found bus numbers and schedules. Great! But...how do tickets work? I see a lot about local zone vs. regional zones (multiple zones?), but no zone map, something about supplements for the city center, all sorts of things I can't figure out. All I want to know is what ticket covers this and how to buy it!
Also, if there is a better nearby mountain/hiking area, I'd be happy to hear about it.
