Luxembourg doesn’t always make it onto the typical Europe itinerary, often overshadowed by its bigger neighbors, but it turned out to be one of the most walkable, easygoing destinations I’ve visited in a while. Compact, scenic, and surprisingly good for wandering without much of a plan, it’s a country that rewards curiosity. Here’s what stood out from my trip, including the one spot that completely exceeded my expectations.
The Highlight: Kasematten der Stadt Luxemburg
If there’s one thing I’d tell anyone visiting Luxembourg City, it’s this: don’t skip the Casemates (Kasematten der Stadt Luxemburg). This underground network of fortified tunnels, carved into the rock beneath the old city, was originally built for military defense, and walking through it feels genuinely adventurous in a way most historical sites don’t. The structure itself is fascinating, with narrow passageways, old cannon openings, and multiple levels connecting throughout the rock.
What really made it memorable, though, was the view. Several openings along the walk look out over the Alzette Valley and the lower part of the city, and the contrast between being underground in centuries-old tunnels one moment and looking out over a scenic valley the next is such a unique combination. If you only have time for one “touristy” stop in Luxembourg City, this is the one I’d prioritize.
Getting Around: Free Public Transportation
One of the most pleasant surprises of the trip was discovering that Luxembourg’s entire public transportation system — buses, trams, and trains within the country — is free. There’s no ticket to buy, no app to figure out, and no fumbling for change. It makes the whole country dramatically easier to explore, especially if you’re staying in the city but want to take a day trip elsewhere.
As a bonus for anyone who tends to run out of mobile data while traveling, city WiFi is available in a number of public areas around Luxembourg City, which was a small but genuinely appreciated convenience.
A Couple of Practical Tips
Luxembourg has a fairly strong Sunday closure culture, with many shops, restaurants, and even some attractions closed for the day. If you’re planning a short trip and want to make the most of your time, it’s worth checking opening hours in advance rather than assuming everything will be open, especially if your visit overlaps with a Sunday.
It’s also worth packing a compact umbrella. The weather can shift quickly, and rain showers are common enough that having one on hand saves you from getting caught out mid-walk.
Touristy Stops Worth Making
Kathedrale unserer lieben Frau (Notre-Dame Cathedral) — Luxembourg City’s main cathedral, notable for its Gothic architecture with later Renaissance additions. It’s centrally located, making it an easy stop to fold into a walking route through the old town.
Abtei Neumünster (Neumünster Abbey) — A former Benedictine abbey that’s since been converted into a cultural center, hosting exhibitions and events. Its location along the Alzette River, beneath the old city fortifications, makes the surrounding walk just as worthwhile as the building itself.
Kasematten der Stadt Luxemburg — As mentioned, an absolute must. Give yourself enough time here to actually explore rather than rushing through, since the passageways and viewpoints are easy to miss if you’re moving too quickly.
Best for Walking: Grund
If you enjoy aimless wandering while traveling, the Grund district is where I’d send you. Sitting in the lower part of the city along the river, below the more commercial upper town, Grund has a quieter, almost village-like feel despite being just a short walk (or elevator ride) from the city center. It’s the kind of neighborhood where the walk itself is the point, rather than any single landmark.
Where to Eat
Brasserie Guillaume was a highlight for food. It specializes in seafood and offers a solid selection of Luxembourgish wine, which isn’t something you see internationally very often, making it a great opportunity to try local wine alongside a proper meal.
Bazaar came recommended by hotel staff as a Michelin-recognized option, though I didn’t personally make it there this trip. It’s on my list for next time, and worth considering if you’re looking for a slightly more elevated dining experience during your stay.
Bakery Stop: Oberweis Grand-Rue
For anyone with even a mild sweet tooth, Oberweis Grand-Rue is worth a visit. The cake selection is extensive, and my personal favorite from this trip was their pain au chocolat, simple, but done really well. They also carry Pâté au Riesling, a savory Luxembourgish pastry filled with meat and cooked in Riesling wine, which makes for an interesting contrast if you want something savory alongside all the pastries.
Final Thoughts
Luxembourg surprised me. It’s compact enough to explore thoroughly in just a few days, but layered enough — between the old town, the underground Casemates, and quieter neighborhoods like Grund — that it doesn’t feel rushed or thin on things to do. Add in free public transportation and a genuinely good food and pastry scene, and it’s an easy country to recommend for a short European getaway, especially if you’re looking for somewhere a little less crowded than the usual capital cities.
