Which cities should a perfect trip to Germany include.
The perfect trip to Germany includes three major cities. If you plan to travel to Germany via plane, it is best to fly into either Berlin, Munich, or Frankfurt airport. These are the biggest airports in the country. From there, you can either travel around by high-speed train or you can take a car and drive on the famous German 'Autobahn.' If you want to experience driving without a speed limit, I would recommend the latter. A perfect trip to Germany must include visiting Munich, Berlin, and Hamburg. All three cities are amongst the largest cities and Germany, with over 1 million people living there, but have each unique cultural as well as historical characteristics. Berlin's present is still influenced by its division into East and West Berlin during the cold war. The city with its two centers is a world city of culture, politics, media, and science. Berlin offers great nightlife, world-class museums, and a lot of sights of historic relevance. Hamburg is known for its port, playing a historic role in trade as a member of the medieval Hanseatic League. The city lies on the River Elbe, and its many canals are crossed by around 2,500 bridges, making it the city with the highest number of bridges in Europe. Munich is the last city you must include on your trip. The city is the largest city in the German state of Bavaria and is well known for its world famous October Fest. Munich is often ranked as one of the most liveable cities in Germany, and attracts visitors with its food culture, parks, and is proximity to the German Alps.
