Things to Do in Luxembourg: 18 Picks From a Local Weekend Trip

Luxembourg City is small enough to walk end to end in under an hour, which is exactly why most people write it off as a day trip from Brussels or a stopover between France and Germany. I did the same thing the first time — took the train in from Trier for six hours, saw the old town, and left. I went back for a proper weekend later and realized I'd rushed the wrong parts and skipped the good ones.

This list of things to do in Luxembourg covers what I'd actually prioritize now: the free public transport system nobody mentions, the underground fortifications that are more interesting than the postcard shots, and the day trips that make the country worth more than an afternoon.

Get the free public transport sorted first

Luxembourg made all public transport — trains, trams, and buses, nationwide — free in March 2020. No ticket, no app, no pass needed for buses and trams within the country. It's the only country in the world that does this, and it changes how you plan a trip here: day trips to Vianden or Echternach cost you nothing but time. The only exception is first-class train seats, which still cost a small supplement, and cross-border trips (to Trier, Metz, or Arlon) that get billed at the domestic rate up to the border.

If you're coming from Frankfurt like I usually do, it's about a 3-hour train via Trier, roughly €35–50 one-way depending on how far ahead you book. From Brussels it's under 3 hours direct, from Paris about 2 hours on the TGV.

Walk the Old Quarter and the Corniche

The Old Quarter (Vieille Ville) is a UNESCO World Heritage Site, and it's genuinely worth the title — narrow lanes, Gothic and Renaissance facades, and fortification walls that wrap around a gorge instead of a flat old town. Start at Place d'Armes, walk to Place Guillaume II, then follow the Chemin de la Corniche, which locals call the "most beautiful balcony in Europe." It's free, open all year, and gives you views over the Alzette valley and the Grund district below. Give it 45 minutes to an hour if you're not stopping for photos every few meters, which you will be.

Come back at night once — the fortification walls are lit and the Place d'Armes cafés stay open late in summer.

Bock Casemates — the actual highlight

The Bock Casemates are 17km of underground tunnels carved into the rock, originally built by the Spanish in the 17th century and expanded by the Austrians and French. This is the one attraction in the city I'd rank above the cathedral. It's cool (literally — bring a layer), a little claustrophobic in the narrower sections, and gives you a real sense of why Luxembourg was called the "Gibraltar of the North."

• Price: around €8 for adults, less for students and kids
• Hours: 10:00–17:30 daily, March through October (shorter hours off-season — check before you go, it does close for winter maintenance some years)
• Time needed: 45 minutes

You can also book a self-guided tour ticket that pairs the casemates with a city train loop if you'd rather not walk the whole old town on foot.

Notre-Dame Cathedral

Notre-Dame Cathedral is the country's only cathedral, built in the early 17th century in late-Gothic style with some Renaissance additions. Entry is free, and it's a 10-minute stop unless you're there for the crypt, which holds the tombs of the Grand Ducal family and John the Blind, King of Bohemia.

• Price: free
• Hours: roughly 10:00–17:00, closed during services
• Honest take: it's fine, not a must-see on its own. Pair it with the Old Quarter walk rather than making a special trip.

Grand Ducal Palace

The Grand Ducal Palace is the official residence of the Grand Duke, and you can only see inside during guided tours in summer (usually mid-July to early September), which need to be booked in advance through the tourist office — they sell out. Outside of that window, you're looking at the exterior from the street, which is still worth a five-minute detour on your way through the old town but not a dedicated stop.

MUDAM — Grand Duke Jean Museum of Modern Art

If you're into contemporary art, MUDAM is in the Kirchberg district in a building designed by I.M. Pei (same architect as the Louvre pyramid). The collection rotates and leans conceptual — go in with that expectation.

• Price: around €8, free on the first Wednesday evening of the month
• Hours: closed Tuesdays, otherwise roughly 10:00–18:00 (later on Wednesdays)

Day trip: Vianden

Vianden is the best single day trip from Luxembourg City and worth building a full day around. The train-plus-bus combo takes about an hour each way (free, per above) and drops you below a castle that actually looks like the fairy-tale version people picture.

• Vianden Castle: around €10 entry, restored from a 10th-century original, open daily with slightly shorter hours in winter
• Chairlift: around €5 one-way, gives you a view over the town and the Our River — I'd do this before the castle for the orientation shot
• Victor Hugo House: small museum in the writer's former home, worth 20 minutes if you have time left

Total time on the ground: 4–5 hours including lunch, which is enough to see everything without rushing.

Day trip: Mullerthal and Echternach

The Mullerthal region, nicknamed "Little Switzerland," is sandstone rock formations, forest trails, and the town of Echternach, which has one of the country's oldest religious sites — the Abbey of St. Willibrord, founded in the 7th century. If you hike, even a short 2–3 hour loop on the Mullerthal Trail near Berdorf is worth the trip on its own. If you don't hike, Echternach's old town and the abbey basilica are still a reasonable half-day.

Bourscheid and Beaufort Castles

Both are 10th–11th century ruins in the north, less crowded than Vianden, and both work as a combined half-day if you have a car — public transport gets you close but not directly to either. Bourscheid has better-preserved fortifications; Beaufort has the more dramatic ruin. If you only have time for one castle day trip, make it Vianden — these two are for people who've already done that and want more.

Moselle Valley wine villages

The Moselle Valley, along the German border near Remich, is where Luxembourg makes its crémant (sparkling wine) and Riesling. It's quiet compared to Vianden, which is the appeal — a slow afternoon of a winery tasting and a walk along the river rather than a checklist of sights. Tastings run roughly €10–15 for a flight at most producers, and the crémant is noticeably underrated for the price.

What I'd skip

The Pfaffenthal lift (the free public elevator connecting the old town to the Grund) gets recommended as an "attraction" in a lot of guides. It's a functional piece of public transit, not an experience — take it if you're walking between neighborhoods anyway, don't detour for it. Same with the Philharmonie concert hall unless there's actually a concert you want to see; the building from outside is a five-minute look, not worth timing your trip around.

Best time to visit Luxembourg

May through September gives you the longest days and the outdoor terraces open, but July and August bring the most tour groups through the Old Quarter. I'd pick late May or September — good weather, thinner crowds. December has a genuinely good Christmas market on Place d'Armes if you're doing a winter Europe trip; just expect the Bock Casemates and some castles to run reduced hours.

Consider travel insurance before you go — it won't change your Luxembourg trip, but it covers the cross-border train delays and lost luggage that actually do happen on multi-country itineraries like this one.

FAQs: Things to Do in Luxembourg

What are the top things to do in Luxembourg? Walk the Old Quarter and the Chemin de la Corniche, go underground at the Bock Casemates, and take the free train out to Vianden Castle for a half-day. Those three cover the city's best free attraction, best paid attraction, and best day trip.

What are some quirky things to do in Luxembourg? Ride the Pfaffenthal lift between the old town and the Grund just for the mechanics of it, or take the free bus to the German border and start the Mullerthal Trail from there instead of driving to a trailhead.

Where should I go for a break in Luxembourg? The Moselle Valley, near Remich. It's a 30–40 minute train ride and the pace is completely different from the city — vineyards, river walks, and a crémant tasting instead of a checklist.

What's a good day trip from Luxembourg City? Vianden. It's about an hour away by free public transport, the castle alone takes 1.5–2 hours, and the chairlift and Victor Hugo House fill out the rest of a comfortable day.

Is Luxembourg expensive to visit? Public transport is free, which offsets a lot. Museum entries run €5–10, and meals are similar to Frankfurt or Brussels prices — expect €15–20 for a casual lunch, more for a sit-down dinner.
