am trying to find the bus schedule from Berchesgaden to Konigsee. I believe it is bus route 843
I think bus 842, the Königssee Express, might be a better option. Complete information for the RVO (Regionalverkehr Oberbayern) can be found at www.rvo-bus.de, but it is in German (why do the Germans make everything in German?). You can see a map of the bus network in Berchtesgaden here. The schedules are here. (Substitute the bus line, 842 or 843 for 841 in the URL).
