No trip to Berlin, Germany, would be complete without some sort of activity that acknowledges the country’ history between 1918 and 1990. During a casual stroll through the city you will come across various museums and monuments, and a paved brick line that criss-crosses the city to outline where the Berlin Wall once stood. And as a solo traveler it is all well and good to stroll around, stopping in areas that catch your interest, but I honestly cannot more highly recommend signing up for a Third Reich Walking Tour if you get the chance.
I firmly believe that everyone should visit a World War II Concentration Camp simply for the reminder of what we are a civilization are capable of. For this reason, and many others, visiting a concentration camp was on my bucket list.
