It is 642 miles (1033 kilometers ) from Copenhagen to Prague, including the boat ride across the Baltic Sea to Germany. This trip runs through Berlin and Dresden in Germany and encompasses three distinct languages plus a change from Eastern to Western Europe. Unlike a national border, the line between Eastern and Western Europe is gradual and is loosely defined by language and culture.
It is 408 miles from Edinburgh to London and although the language is similar, the culture does change somewhat, even though both places are located within the United Kingdom. To be exact, Edinburgh is part of Scotland and London is part of England. Local dialects in the rural areas in both these parts of the UK can be quite strong.
From Hamburg to Munich, this journey of 470 miles (755 kilometres) takes place in Germany only. Hamburg is located in the north of the country near the Baltic and Munich is located in the south near the Austrian border. The language here is very much the same, but there is some variation in culture that exists between the northern and southern parts of Germany. By European standards this is a long trip, considering all the traveling takes place in one country.
This is a long journey of 1305 miles (2099 kilometers) that crosses three large countries that speak a Latin or Romance language. They are Spain, France and Italy and it is an interesting side note that the two non-connecting countries, Italy and Spain, have the two languages that are most similar.
This is actually a shorter journey than going from Madrid to Spain. The trip is only 1119 miles in length, which is the same as 1799 kilometers, but this journey crosses more culturally diverse terrain, because the voyage will take you through an English speaking country (England) and perhaps a German speaking one as well (Germany or Switzerland), depending on your route.
