I spent ten days in Germany this summer. We spent one night in Salzburg, which was about a four hour car ride from Munich. I think the consensus was that one night was not enough in Salzburg, but we really enjoyed the time that we did spend there. There are tons of trips that you can take from there, the Eagles Nest was the one I was most interested in (and the Sound of Music tour!). We also spend a couple nights in Garmisch, which I believe is a couple hours from Munich, but was a good point from which to visit Neuschwanstein, the Zugspitz (the highest point in Germany), and where you can do some hiking in Park Nock Guell (sp?) and other outdoor activities. We stumbled upon a very fun Alpine Festival while in Garmisch that was basically a summer version of Octoberfest and it was AWESOME. A little bit further from Munich, about three hours to the West, is Rothenburg ob der Tauber, which is in my opinion, is definitely worth the trip. It is a really cute and beautiful walled city, and may have been the highlight of my trip.
