We fancy visiting Bavaria next year but it is such a diverse area I'm not sure where to base us. We would be flying so no car and we like to walk (15k no problem) but we are not actual hikers. Is Berchtesgaden a good place to stay for a week? Is there plenty to see and do in the area? I think, too, it would be easy enough to get to from Salzburg airport and we'd probably use taxis for transfers. How much would they cost?
