The third part of my adventure in Germany was a day trip from Munich to Zugspitze, the highest mountain in Germany.
I began the day just before 6am putting on many thermal layers and then looking like a bit of a fool catching the U-Bahn to the München Hauptbahnhof. From München you catch a train for about an hour and a half to Garmisch-Partenkirchen, where you switch to the Bayerische Zugspitzbahn (cogwheel/rack railway) to get to the mountain.
Halfway along the railway you can switch to the Eibsee Cable Car that takes you directly to the top of Zugspitze. This is what I did as it was the fastest and most spectacular way to get to the top of the mountain.
