Luxembourg in euros: free buses and trains, French-German-Luxembourgish, 112, traveler tips, and an eSIM for a country you cross in an hour.
Sichere, effektive und private eSIMs auf der ganzen Welt
Luxembourg is a grand duchy the size of a large national park, with a capital that still has a fortress in its bones: the casemates, a viaduct view, and a Kirchberg plateau of EU glass that feels like a different town. You can ride a tram across the whole story. Since 2020, buses, trams, and second-class trains have been free nationwide — the rare travel fact that is both true and useful every single day.
The country speaks Luxembourgish, French, and German in the same café, sometimes in the same sentence. English is widely usable in the city. Menus switch language without apology; you should too. The currency is the euro. 112 is the general emergency number; 113 reaches the police. Tap water is fine. Plugs are Type C/F.
Leave the capital. Vianden's castle above the river is the fairy-tale half-day. The Mullerthal — Luxembourg's Little Switzerland — is sandstone trails and gorges, not a slogan. The Moselle is wine villages and a slower clock. Cross-border workers flood the roads at rush hour; the free train is how you refuse to sit in that car park.
A first trip that works is two nights in Luxembourg City plus one landscape, not a checklist of every commune. Eat gromperekichelcher, a pastry that has more butter than language, and a glass of local crémant. The duchy is small. That is the luxury: you can understand it without rushing.

Ride second class without a ticket inside the country. Crossing into France, Belgium, or Germany can put you back in paid territory. Check the journey, not the slogan, when the destination is Metz or Trier.
Bonjour, guten Tag, or moien — then English if needed. Starting in English in a village bakery is fine; starting mid-order without a greeting is the same mistake as in Paris.
Walk the Chemin de la Corniche, do one underground stretch if you like tunnels, and eat in Grund or Clausen rather than the first terrace on the bridge.
Pick a marked loop, wear shoes that can take mud, and screenshot the return bus from Echternach or Berdorf. Treating it like a city park walk is how you miss the last ride.
If you must move at 8am or 6pm, take the free train. The motorways toward France and Germany are why the free-transit policy exists.

There is no castle train. Ride to Ettelbruck, take the hourly bus to Place Engelmann, then walk the steep Montée du Château. That last stretch is the price of the turret view.

CFL upgrades, especially at weekends, turn a simple Ettelbruck change into a slower puzzle. Check mobiliteit.lu the night before you promise anyone a casual castle morning.

Yes, on buses, trams, and 2nd-class trains inside Luxembourg. First class and many cross-border legs are not free. Carry ID if asked; it is still a real network, not an honor-system rumor.
French and German both work in the city; Luxembourgish is welcome. English is widely understood in hospitality. Greet first, then speak. A translation app on mobile data covers the village menu.
Maps and messaging in a compact country: a small plan is enough unless you are on work calls. Download Mullerthal tiles if you hike.
You can. An eSIM means the first free bus is already in the app, which matches how this country is designed to be used.
Only on a regional Europe plan. The borders are minutes away. A country-only eSIM will die on a day trip to Trier or Metz.
eSIM-Tarife
Even with free trains, you still need a map, a tram time, and a translation of a menu that flipped from French to German. A prepaid eSIM is online at Findel before you ride into the valley, with no kiosk for a country you might leave tomorrow.
If Trier, Metz, or Arlon is on the weekend plan, use a regional Europe eSIM. Luxembourg-only data stops where the fare-free zone stops.
