I will be in Munich for about a week (Saturday -- Friday) for the Bavarian State Opera festival. The performances are on Sunday, Tuesday and Thursday evenings. I've been to Munich once before, and there are definitely things I wanted to see but wasn't able to. For those, I am thinking I will tackle on the performance days. On the 2 off-days (Monday and Wednesday), what would be some doable day-trips, keeping a home base in Munich?
I've been to Salzburg and don't really want to tackle the Ludwig castle crowds in the summer.
