Most visits to Luxembourg are trouble-free but you should be aware of the global risk of indiscriminate international terrorist attacks, which could be against civilian targets, including places frequented by foreigners.
Luxembourg has a number of minor rivers, such as the Eisch, the Alzette, and the Pétrusse, but the main river is the Moselle with its tributaries-the Sûre and the Our. Together, their courses serve as a natural boundary between Luxembourg and Germany. Along their banks, many of the country's medieval castles can be found.
In 1993 it was reported that Luxembourg had the highest worldwide per capita consumption of alcohol; an average of three beers a day for every man, woman, and child. French wine is the most commonly drunk alcohol, and fine beers from Germany and Belgium are widely available.
