One of my last adventures in Germany was a trip to a zip lining adventure park, Abenteuerpark Schloss Lichtenstein, close to Reutlingen. I've been to the same one about a year ago but they have so many different zip lining routes that it didn't matter.
This time I went with a big group of friends including my roommate Tine.
If you have never been to a zip lining park before, it is so much fun, if you aren't afraid of heights.
