My wife and I will be staying with German friends for a few days in late August this year and have one day we need to fill with them. They live in Oberhaching just south of Munich, so we thought of checking out one or two towns or villages within a couple hours from there on a day trip. We've been to Ludwigs castles, Garmish-P, Fussen, Oberammergau previously and don't need to revisit those, although that isn't out of the question.
Looking for suggestions on destinations for the day please. Our German friends will have a vehicle. We enjoy simply strolling around authentic old town areas connecting with the locals, checking out architecture, people watching, stepping into cafés, and great meals (..and beer, of course).
