Garmisch-Partenkirchen was founded by uniting the two towns of Garmisch and Partenkirchen by a decree of Adolf Hitler to bring the 1936 Winter Olympics to Germany. The International Olympic Committee was going to pass over Germany as the host, because there were not enough hotel rooms in the host town, so Hitler forced the unification of Garmisch and Partenkirchen to create a larger town, which would be more appealing to the IOC.
Garmisch is less than an hour by car from Munich, and the ride is a beautiful stretch of Autobahn, unfortunately not the whole way. Expect to drive up to three hours on weekends and public holidays.
Also, trains leave to and from Munich every hour, and the (beautiful) ride lasts roughly 80-90 minutes.

Lines #1 and #2 run every 20 minutes (30 minutes on weekends) and head from the Klinikum(hospital) via Bahnhof(trainstation) to Kreuzeck(skiarea)or Breitenau(US-facilities).
