Visiting Luxembourg: a practical guide

As of today there is no scheduled nonstop flight between the United States and Luxembourg: the airlines serving Findel connect through European or Turkish hubs, so most US travellers arrive via Frankfurt, Paris, Amsterdam, London, Istanbul or Lisbon.

That is about to change. On 25 August 2026 United Airlines announced daily Newark to Luxembourg service with the Airbus A321XLR, starting 2 April 2027. It would be the first scheduled nonstop link between the two countries, and it is the single biggest change to how Americans reach Luxembourg in a generation.

Luxembourg is in the euro area and in the Schengen area, so one entry covers most of Western Europe. Power is 230 V at 50 Hz with type F Schuko sockets: bring an adapter, and a converter for anything that is not dual-voltage.

Since a ministerial regulation took effect on 29 February 2020, buses, trams and second-class trains are free to everyone inside the country, residents and visitors alike, with no ticket needed. Luxembourg is the first country to have done this nationwide, and it is not a promotional scheme: you simply board.

There are exactly two exceptions worth knowing. First class on CFL trains is paid (3 euros for a two-hour ticket, 6 euros for a day). And free travel stops at the border: a cross-border journey needs a RegioZone ticket, 3 euros for two hours or 5 euros for a day, although second-class trains as far as the border stations at Athus in Belgium and Audun-le-Tiche and Volmerange-les-Mines in France remain free.

The policy shows in the numbers the government published after five years: rail ridership rose from 25 million passengers in 2019 to 31.3 million in 2024, and tram ridership from 6.2 million to 31.7 million.

Since 2 March 2025 the tram runs to the airport itself. A 3.9 km extension, including a 110-metre structure spanning the A1 motorway, added the Heienhaff park-and-ride interchange and the Findel terminus, so line 1 now covers 16 km end to end from the airport to Stadion, serving 24 stations and ten interchange hubs including Luxexpo on Kirchberg, Hamilius in the centre and the central station.

Trams run every day including public holidays. The airport branch runs every eight minutes by day, the central section every three and a half to four minutes. The first tram leaves Findel at 05:03 on weekdays and the last at 00:06 every day; in the other direction the last tram going all the way to the airport leaves Stadion at 23:17 Monday to Saturday and 23:12 on Sundays and holidays.

Buses 16 and 29 also link the airport to the central railway station every ten to fifteen minutes. All of it is free. No official source publishes an end-to-end journey time for the tram, so rather than invent one: check the live journey planner at mobiliteit.lu, and allow more time than a taxi would take.

The old quarters and fortifications of Luxembourg City have been on the UNESCO World Heritage list since 17 December 1994, and the reason becomes obvious the first time you stand on the Corniche and look down into the Grund. The city is built across a gorge; the walk down and back up is the sightseeing.

Under the Bock promontory run the casemates, the tunnels carved into the rock by successive occupiers. About 17 kilometres of them survive the demolition that followed the 1867 Treaty of London. The Bock Casemates admit visitors seven days a week, every fifteen minutes, from 09:45 with last admission at 19:00 and a maximum visit of 45 minutes, closing only on 25 December and 1 January. Admission is 11 euros for adults, 9 for students and visitors aged 60 and over, 5.50 for children from 4 to 12, and free below 4.

The best view in the city, though, costs nothing. The Pfaffenthal panoramic elevator drops 71 metres from the Pescatore park down into the Alzette valley, it is free, and it runs daily from 05:45 to 01:00.

Vianden Castle, an hour north, is the one castle to pick if you only pick one. It opens daily from 10:00 year-round, closing at 18:00 from April to September, 17:00 in March and October and 16:00 in the winter months, with last entry half an hour before. Admission is 13 euros for adults, 7 for students aged 13 and over with a card, and 4 for children from 6 to 12, each including a 1 euro municipal tourist tax.

East of the capital, the Mullerthal is what Luxembourg calls its Little Switzerland: sandstone formations, moss, narrow passages between rocks, and waterfalls. The Mullerthal Trail runs 112 kilometres across three main routes and five shorter ExtraTours, and holds the European Leading Quality Trails label. To reach its gateway town of Echternach, take the tram to Kirchberg Luxexpo and change to bus 201, direct every half hour.

South and east, the Moselle valley makes crémant and Riesling on terraced slopes around Remich and Grevenmacher, and Belval in the south turned its blast furnaces into a university campus you can walk through. All of it is inside a country you can cross in ninety minutes, on transport that costs nothing.

Summers are mild rather than hot. MeteoLux's 1991-2020 normals for Findel give mean daily maxima of 21.7 °C in June, 23.9 °C in July and 23.5 °C in August, with minima around 12 to 14 °C: pack a layer even in July.

Three moments are worth planning around. National Day is 23 June, but the celebration is the evening before, with the changing of the guard at the Grand Ducal Palace, a torchlight procession through the city and concerts. The Schueberfouer, a funfair that has run since the fourteenth century, fills the Glacis for three weeks from late August. And the Winterlights season, which is the umbrella for the Christmas markets, runs from 20 November 2026 to 3 January 2027.

In between, the Luxembourg City Tourist Office's Summer in the City season, 12 June to 18 September 2026, bundles open-air concerts, exhibitions and guided tours. Whatever week you land in, the events agenda on this site lists what is actually on, verified by hand.

Luxembourgish is the national language, and Luxembourgish, French and German are the official ones. English has no official status, but the national tourist board lists it first among the languages widely spoken here, and in the capital you will be understood almost everywhere.

Tipping is not the American ritual. Luxembourg law requires bars, hotels, restaurants and tea rooms to advertise their rates service included, and displayed prices must include VAT and every other tax. Rounding up is courteous; a fifteen to twenty percent calculation is not expected.

Shops keep continental hours: under the rules in force since 19 June 2026, retail may trade from 05:00 to 21:00 Monday to Friday and 05:00 to 19:00 on Saturdays, Sundays and public holidays. Sunday trading exists but is limited, so do not plan a Sunday around shopping.

Museums are cheaper than you expect, and sometimes free. The Lëtzebuerg City Museum charges 5 euros, is free for anyone under 21, and opens free to everyone on Thursday evenings from 18:00 to 20:00. The Nationalmusée charges 7 euros and is free for under-26s. Mudam, the contemporary art museum on Kirchberg, charges 10 euros and closes on Mondays. Museum Mondays are a real risk: several close.
