Overview and Things to Consider
Luxembourg is one of the three remaining Grand Duchies in the world and has been occupied, annexed, and guaranteed neutral more times than any nation its size should reasonably have to endure. The country achieved permanent neutrality in 1867, was occupied by Germany in both World Wars, and joined the founding group of the European Union. Luxembourg City serves as one of the three capitals of the EU and hosts the European Court of Justice. The country is very wealthy - GDP per capita is among the highest in the world - and prices reflect this.
Luxembourg City is the main draw and can be done in two full days. The old town (Ville Haute) on the plateau above the valleys, the Grund neighborhood below in the valley, and the Kirchberg plateau with its modern EU quarter create a city with unusual topographical character. The Casemates du Bock - a network of underground fortifications carved into the sandstone - are the most distinctive sight in the country.
Getting There and Around
Luxembourg Airport (LUX) is compact and well-connected to Brussels, London, Frankfurt, Paris, and other European hubs. Luxair is the national carrier; budget carriers also serve the airport. The airport is 6km from the city centre; a free shuttle bus and cheap taxi make it accessible. Luxembourg is famously the first country in the world to make all public transport (trains, buses, trams) free for passengers - since March 2020, you pay nothing to use any public transit in Luxembourg.
Within Luxembourg City, the free bus and tram network covers everything. The city is also very walkable, particularly between the old town, the Grund valley, and the Pfaffenthal. For the Ardennes and Moselle Valley regions, a rental car or the national train/bus network work - Luxembourg is small enough that no journey within the country takes more than 90 minutes.
What's Changed Since 2016
The free public transport policy (implemented 2020) was a globally noted experiment that has made the country easier and cheaper to get around than any other in Europe. The policy has not significantly reduced private car use (car ownership remains high) but has made it more convenient for visitors and commuters who cross from France, Belgium, or Germany daily.
Luxembourg City's Kirchberg district (the EU quarter) has expanded with new cultural institutions - the Philharmonie Luxembourg (concert hall) and MUDAM (Museum of Modern Art) are both worth visiting and were developed in the city's push to position itself as a cultural capital alongside its financial reputation. The city's restaurant scene has improved, with more independent dining options rather than just expense-account restaurants for EU civil servants.
Ideas to Consider for Your Visit
The Casemates du Bock are the defining Luxembourg experience - a 23km network of tunnels and casemates carved into the Bock promontory from the 10th century onward, used as shelter during WWII for up to 35,000 people. Open from March through October. The view from the Chemin de la Corniche (called 'the most beautiful balcony in Europe' by visitors since the 17th century) across the Alzette valley and the Grund below is the city's defining visual.
The Ardennes region in the north of Luxembourg has Vianden Castle (a fully-restored medieval castle in a river valley that's one of the best-preserved in Europe), the town of Echternach (Luxembourg's oldest town, with an extraordinary Basilica of St Willibrord), and hiking trails through beech forests and river valleys that are quiet and beautiful outside summer weekends.
The Luxembourg Moselle wine region along the southeastern border with Germany produces Riesling, Pinot Gris, Pinot Blanc, and Crémant de Luxembourg sparkling wine. The villages along the river - Remich, Grevenmacher, Stadtbredimus - have wine estates offering tastings. Luxembourg Moselle wines are little-known internationally and well-priced for their quality.
Realities to Be Aware Of
Luxembourg uses the euro and is expensive - one of the most expensive countries in Europe for accommodation and dining. Mid-range hotel in Luxembourg City: €150-250 per night. Restaurant meal: €20-40 per person for a main course. The free public transport offsets some of this. Many travelers visit Luxembourg as a day trip from Brussels (2 hours by train), Trier in Germany (50 minutes), or Metz in France (50 minutes), which avoids the hotel cost entirely.
If Luxembourg Is Part of a Longer Trip
Luxembourg sits at the crossroads of Belgium, Germany, and France. The Benelux circuit (Brussels, Bruges, Luxembourg, and connecting towns) is a natural two-week Western European itinerary. The German Moselle wine country continues from Luxembourg's Moselle right into Germany - a wine-focused trip that crosses the border seamlessly.
Yearly Things to Consider
Luxembourg has a temperate continental climate - four proper seasons, with cold but usually snow-free winters in the city and colder, snowier winters in the Ardennes. Spring and autumn are pleasant for the city and for hiking. Summer is warm and the most popular for the Ardennes and Moselle. The country is small enough that weather variation within it is more about altitude (the Ardennes plateau versus the Moselle valley) than north-south differences.

Ideas for Itineraries
3 Days in Luxembourg
Three days covers Luxembourg City properly and adds a regional excursion. Day one: the old town (Chemin de la Corniche, Bock Casemates, Cathédrale Notre-Dame), the Grund valley below. Day two: MUDAM museum and the Kirchberg European quarter in the morning, afternoon at the Luxembourg American Cemetery and Memorial (Patton is buried here). Day three: drive or train to Vianden Castle in the Ardennes, returning in the evening.
5 Days in Luxembourg
Add overnight in the Ardennes - base in Vianden or Echternach for two nights, hike through the Mullerthal trail region (the Luxembourg's Little Switzerland area, a sandstone canyon landscape east of the capital), and stop at Echternach Abbey. A Moselle Valley afternoon with wine tastings at Remich can be added on the final day back toward Luxembourg City.
1 Week in Luxembourg
A week in Luxembourg makes most sense as the country itself plus day trips across the borders to Trier (50 minutes, Roman Porta Nigra and cathedral), Metz (50 minutes, excellent Gothic cathedral and the Pompidou Centre Metz), and the Belgian Ardennes (Bouillon Castle, Han-sur-Lesse caves). Luxembourg is genuinely better as a base for the greater Ardennes region than as a standalone destination.
2 Weeks or More in Luxembourg
Two weeks based in Luxembourg City makes sense for people working or doing business in the EU quarter - the city has a significant international community and good quality of life infrastructure. For travelers, two weeks in the Luxembourg region means combining it with Belgium (Brussels, Bruges, Ghent are all within 2 hours), the German Moselle, and Alsace in France. Luxembourg itself is small but the surrounding region is substantial.
Luxembourg Travel FAQ
Yes. Since March 2020, all standard class public transport in Luxembourg - trains, buses, and trams - is free for all passengers. No ticket needed for second class travel within Luxembourg. First class on trains still requires a ticket. The policy applies to everyone including visitors. The entire country's network runs on a single system and free transit covers all of it.
Two full days covers Luxembourg City properly: the old town and Casemates, the Grund valley, the Kirchberg cultural and EU quarter, and the American military cemetery. A day trip from Brussels, Trier, or Metz is possible and viable for a quick visit, but you'll miss the city at night and the slower pace that lets the dramatic topography sink in. Two nights is the right minimum if you're treating it as a destination.
Vianden is a medieval castle in the Our River valley in northern Luxembourg, dating from the 10th century and extensively restored in the 20th. It's one of the largest and best-preserved medieval castles in Europe outside of France. The village below the castle is charming, the cable car up gives good valley views, and the castle interior has good interpretive materials about Luxembourg's medieval history. An hour and a half from Luxembourg City by bus or car.
Luxembourg has three official languages: Luxembourgish (Lëtzebuergesch, used in daily conversation), French (used for legislation and administration), and German (used in media and education). Most Luxembourgers speak all three plus English. In practice, travelers are served in French, German, or English without difficulty. Luxembourgish, a distinct Germanic language, is not expected of visitors but a 'Moien' (hello) is appreciated.
Depends on your interests. As a day trip from Brussels or Trier, you can see the Casemates and Chemin de la Corniche adequately. As a destination, two nights in the city plus a night in the Ardennes gives you a genuinely distinctive experience - the underground fortress system, the valley topography, and the Ardennes castle and forest landscape are not replicated elsewhere in the region. It's expensive, but the free public transport and shorter distances mean overall costs compare reasonably to neighboring countries.
