Getting around Luxembourg: trains, buses, driving and domestic flights

Luxembourg is small enough that one mode covers most trips. Trains run the north–south spine and the Moselle; buses fill in the villages and the Müllerthal. Fares inside the country are zero in second class, so the decision is about time and frequency, not money.

The table below is the short version. Details for each mode follow.

Second-class travel on CFL trains and RGTR buses inside Luxembourg is free, including the tram in Luxembourg City. You do not need a ticket or a pass for domestic journeys. First class on trains is paid, and any leg that crosses into Belgium, France or Germany needs a ticket for the cross-border section.

The train network is a north–south spine: Luxembourg City to Ettelbruck takes about 30 minutes, and on to Clervaux about an hour. A branch serves the Moselle, useful for Remich, Wasserbillig and the wine villages. Buses cover what the rails miss: Luxembourg City to Echternach is about an hour, and Diekirch to Vianden about 20 minutes.

The main trap is frequency, not fare. Evening and Sunday service outside the capital thins out, and some village routes run a handful of times a day. Plan the last bus back before you set out, and keep a fallback in mind. Use the Mobiliteit.lu app or website for times, platforms and disruptions.

Luxtram links the airport at Findel with Kirchberg, the Gare and Bonnevoie, which makes it the simplest way between the airport, the EU quarter and the station. It is free, and it avoids the traffic and parking costs of driving into the capital.

In the city centre, buses and the tram cover the main axes, and the Pfaffenthal lift and the Kirchberg funicular connect the old town, the Alzette valley and the Kirchberg plateau in a minute or two. Both are free. Expect queues at the lift on weekend afternoons.

Tram extensions open in stages, so check the current line before relying on a stop that appears on an old map.

A car is not needed for the standard first trip. Trains and buses reach Luxembourg City, Vianden, Echternach, the Moselle and the Müllerthal, and parking in the capital is paid and tight. Rent a car only if your plan centres on remote Éislek villages where buses are sparse.

If you do drive, expect rush-hour congestion on the approaches from Belgium, France and Germany, and paid parking in Luxembourg City. Fuel is cheaper than in some neighbouring countries, which is why cross-border drivers fill up here. Roads are good and distances short: anywhere in the country is under about 1 h 30 from the capital.

Cycle paths follow the Moselle and old rail lines, which makes bikes a good fit for the river valley and the Müllerthal. Vel'OH! is the city bike-share scheme, with a low-cost subscription; short rides are the usual pattern.

The capital and the north are hilly, so an e-bike helps if you are not a regular cyclist. Walking covers the old town and most village centres; outside them, distances between villages are too long to walk as transport.

Tap water is safe to drink, so refill a bottle rather than buying water for short trips. Public toilets in the capital's centre are free; elsewhere, cafés expect you to be a customer.

Most shops close on Sunday, and many museums close on Monday or Tuesday, which affects how you plan a day around transport. If you are relying on a bus to a museum or a village, check both the timetable and the opening day.

Vianden is the classic car-free day trip: train to Ettelbruck or Diekirch, then a bus of about 20 minutes up the valley. Echternach is about an hour by bus from Luxembourg City and pairs well with the Müllerthal trails. The Moselle villages — Remich, Wasserbillig — sit on the train branch.

For all of these, the constraint is the return service, especially on Sundays and in the evening. Fix your last connection before you leave the capital, and treat the free fare as a reason to travel light rather than a reason to improvise.
