Rules in force · 10Non-EU visitors get 90 days in any rolling 180-day window…The Grund and Clausen lie far below the upper town
  • Europe ↗Non-EU visitors get 90 days in any rolling 180-day window, counted across all 29 Schengen states together — not per country; the Entry/Exit System now logs each crossing, so an overstay is detected automatically.
  • Europe ↗On the first Schengen entry since EES began, non-EU travellers give four fingerprints and a face photo at the border instead of a passport stamp; there is nothing to apply for or pay in advance.
  • Benelux ↗Dutch and Belgian police can ask anyone to show identification (in the Netherlands from age 14): carry the original passport or EU ID card — a photocopy is not accepted.
  • Benelux ↗Tap-in fares, Dutch and Belgian domestic tickets and Luxembourg's free transport all stop at the border: buy an international ticket for cross-border legs, or you will be fined on board.
  • 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.
