Who talks about the 'Grand Duchy of Luxembourg', appoints immediately the most striking feature of the country, namely its size or better said: his greatness in small things. 'Big' is the duchy only 80 km (50 miles) from north to south, while it's from east to west even less than 60 km (37 miles). The name 'Luxembourg' ('little castle') gives a better description of the true country. In Luxembourg you can visit picturesque places along the Moselle and in the Luxembourg Ardennes in the north. Public transport is very well arranged at low prices. Mullerthal - called also Little Switzerland - is the most popular tourist region because of its beautiful landscape with rocks, waterfalls, forests and rivers. It's actually the valley of the river Muller at the border with Germany. The largest town there is Echternach.
