Munich has 6 breweries you could visit...
I lived in Augsburg for 4 years. It's about 40 miles west of Munich.
Kloster Andechs (been there 4-5 times)and Hofbrauhaus (at least 50 times) are always good, but if you go north of Munich there's Aying and Erding if you like Hefe Weizens.
Between Ingolstadt and Munich is the Hallertau hops growing region. Look for signs that say "Hopfenstrasse" (Hop Street).
While it's certainly not fun in any sense of the imagination, I also recommend that you tour Dachau Concentration Camp. It's about 13 miles NW of Munich.
