My family and and I moved to Germany two years ago due to my husband's job with the U.S. Department of Defense. As (happily) displaced Americans, we feel über-blessed to be surrounded by world-famous castles and museums. I relish my time at the local saunas, my husband loves going out with his buddies for bratwurst and beer, and my son gets a kick out of playing among castle ruins.
So far, our favorite field trip has been to the Barefoot Park (Bad Sobernheim Barfußpfad), a 2-mile walking trail along the Nahe River in Southwestern Germany. Barefoot parks range from short trails (100 yards or less) to longer loops, such as the one we experienced. They're unpaved, with varying surfaces ranging from dirt to wood chips to rocks of all shapes and sizes. Sometimes they have obstacles, such as water features or wooden bridges. The park we experienced was the first of its kind in Germany, and to this day, Germany has the most barefoot parks in Europe.
