Berchtesgaden-Salzburg-Munich on Lander Ticket?

As long as you go from Berchtesgaden to Salzburg via Frielassing you'll be covered. There is also a bus (RVO 840, the Watzmann Express) down the river from Berchtesgaden to Salzburg, but it goes through Austria and wouldn't be covered by the Bayern-Ticket.

If you go to Munich later in the day, that will be covered by the Bayern-Ticket, as well. And the starting time limit is 9 AM.

Thank you, Lee. I knew you'd have the answer.
