  • Luxembourg ↗Luxembourg is in the EU and the Schengen area; the EU Entry/Exit System applies to non-EU visitors. Check the official EU and Luxembourg sources for your passport.
  • Luxembourg ↗Public transport inside Luxembourg is free in second class; cross-border trips and first class still need tickets.
  • Luxembourg ↗Luxembourgish, French and German are official; English is widely understood in the capital.
  • Luxembourg City area ↗Rural buses run less often in the evening and on Sundays: check the return time before you leave the city.
  • Luxembourg City ↗The Grund and Clausen lie far below the upper town: paths and lifts exist, but with large bags take a taxi to the door rather than the stairs.
  • Luxembourg City ↗Buses, trams and trains inside Luxembourg are free in second class: no ticket is needed for a city trip, but cross-border and first-class travel is paid.
