This city is the official border between Europe and Asia. You can even skip several times from Europe to Asia and back and of course take a photo standing in two parts of the world simultaneously. The Soviet artifacts, historical references to the last resort of the last Tsar and his family, mixed architecture and friendly locals create the vibrant picture of Ekaterinburg. If youre more into heritage and traditions you'll definitely enjoy the tours to the villages of Koptelovo and Verkhnee Dubrovo to see the traditional architecture and get to know the locals.
