Deep in the south of Germany, close to the highest point in the country, Zugspitze, you can cross the border with Austria on foot. In fact you can walk over the border from the German state of Bavaria into Austrian Tyrol as many times as you wish. (Just don’t forget to switch your mobile data off as needed – if you’re using a German SIM card you’ll be roaming as soon as you cross the border.)
Hiking over the German-Austrian border in the Alps (easier than you may think)
