A 17,000-foot tunnel network cut into a cliff, a castle Victor Hugo sketched from exile, sandstone canyons barely wider than your shoulders, and a wine valley that shares its slopes with Germany — Luxembourg packs an outsized range of Europe into one of its smallest countries. This five-day route covers the fortified Old Town and a Michelin table in Luxembourg City, Vianden’s hilltop castle, the Mullerthal Trail’s “Little Switzerland” rock formations near Echternach, and Crémant tastings along the Moselle — all linked by a genuinely useful fact: Luxembourg has run its entire national public transport network free of charge since 2020, so getting between all of it costs nothing at all.
Day 1Casemates & the Corniche
Land at Luxembourg Airport and take the free public bus straight into the Old Town — Luxembourg has run its entire national rail, tram and bus network fare-free since 2020, so today’s only transport cost is your own two feet. Spend the afternoon inside the fortress that gave the city its name.
🛎️ Check-In — Hotel Le Place d’Armes
Check-in 3pm · from €340/night
This Relais & Châteaux boutique hotel occupies a row of restored 18th-century townhouses right on the Place d’Armes, the city’s central square. Rooms mix exposed stone and timber beams with underfloor-heated marble bathrooms, and the rooftop spa looks out over the Old Town rooftops — an easy walking base for everything on the next two days.

🏰 Bock Casemates & Chemin de la Corniche
2–3 hrs · €9/adult (casemates)
Descend into the Bock Casemates, the 17,000 feet of tunnels carved into the cliff by the Spanish, Burgundians and Prussians over four centuries of fortification — part of why UNESCO calls Luxembourg’s Old Town “one of the greatest fortified sites in Europe.” Climb back out and walk the Chemin de la Corniche along the ramparts above the Alzette River, often billed as “Europe’s most beautiful balcony,” with the Grund quarter’s spires laid out below.
🍽️ Dinner — Brasserie Restaurant Um Dierfgen
Dinner · €28–35/person
Start with the national dish: judd mat gaardebounen, smoked collar of pork simmered until it falls apart and served with broad beans and boiled potatoes, at this old-town brasserie a short walk from the Place d’Armes. It’s hearty, unfussy Luxembourgish cooking, and a good first taste of a cuisine that borrows equally from France and Germany.

Day 2Grund, Kirchberg & a Michelin Table
Ride the free tram or simply walk down into Grund, the riverside quarter tucked below the fortress walls, then spend the evening at one of the country’s most celebrated tables.
🚋 Free Nationwide Public Transport
All day · €0 — free since March 2020
Luxembourg became the first country in the world to make every train, tram and bus free nationwide, a policy now several years in and still running. Use it today to loop between neighborhoods with zero planning: the funicular and elevators linking the Old Town to Pfaffenthal and Kirchberg run on the same free network, so there’s no reason not to ride down, walk along the river, then ride straight back up.
📸 Grund Quarter & the Wenzel Walk
Half day · self-guided, free
Follow the Wenzel Circular Walk down through Grund, where the Alzette River curls past Neumünster Abbey and pastel townhouses now hold wine bars and small galleries. The Pfaffenthal lift and glass funicular (also free) haul you back up to the Kirchberg plateau in under two minutes if you want to see Luxembourg’s modern EU quarter for contrast before heading back to the Old Town.
🍷 Dinner — Mosconi
Dinner · tasting menu from €145/person
Chef Ilario Mosconi has held a Michelin star at this Grund riverside dining room for years, pairing northern-Italian technique with Luxembourgish and Moselle-valley ingredients — expect handmade pasta, game in season, and a wine list heavy on Riesling and Crémant from the valley you’ll visit on Day 5. Reserve at least two weeks ahead; the terrace tables over the river go first.

Day 3North to Vianden
Ride the free regional bus north into the Ardennes to Vianden, a riverside town dominated by one of the largest and best-restored castles in Europe.
🚌 Transfer — Luxembourg City to Vianden
≈50 min · €0 (free public bus, Line 570)
The regional bus climbs out of the city and into rolling Ardennes farmland before dropping into the Our River valley at Vianden — and like every other bus and train in the country, it’s free. Leave the Place d’Armes by mid-morning to arrive with a full afternoon at the castle.
🏰 Vianden Castle
2–3 hrs · €10/adult
This 11th-to-14th-century castle stacks Romanesque, Gothic and Renaissance wings up a wooded hillside above the town, and its scale and restoration make it one of the most complete feudal castles in Europe — Victor Hugo sketched it repeatedly during his exile here. Walk the armory, the Knights’ Hall and the covered walkway before riding the chairlift above town for a wide view back down over the whole fortress and valley.
🛎️ Check-In & Dinner — Hotel Heintz
Check-in 3pm · from €120/night · dinner €30–40/person
This family-run riverside hotel sits right on the Our, a five-minute walk from the castle’s base, with a terrace restaurant serving regional Ardennes and Luxembourgish cooking — trout from the river is the thing to order. It’s simple, comfortable, and about as close to the castle gate as you can sleep.

Day 4Mullerthal Trail & Little Switzerland
Bus south to the Mullerthal region — nicknamed “Little Switzerland” for terrain that has nothing to do with the Alps and everything to do with dramatic sandstone — and spend the day walking one of Europe’s most underrated hiking trails.
🚌 Transfer — Vianden to Echternach
≈45 min · €0 (free public bus)
The free bus network connects Vianden to Echternach with one change, cutting south through the Ardennes foothills into the Mullerthal region. Drop your bag at the hotel before heading out to the trailhead.
🪨 Mullerthal Trail: Perekop & Schiessentümpel Loop
4–5 hrs · ∼9 miles · free
The Mullerthal Trail’s sandstone corridors are the reason for the region’s nickname: the Perekop passage squeezes the path between moss-covered rock walls barely wider than your shoulders, and the Schiessentümpel waterfall — arguably Luxembourg’s most photographed spot — drops over a stone arch bridge into a still pool ringed by ferns. Loop back through Berdorf for a coffee before the return bus.
🛎️ Check-In & Dinner — Hotel Bel-Air Sport & Wellness
Check-in 3pm · from €140/night · dinner €30–40/person
This Echternach hotel sits on the edge of town with its own pool and sauna — a welcome reset after a full day on the trail — and a dining room serving regional dishes with produce from the surrounding valley. Ask for a room facing the garden rather than the road.

Day 5The Moselle Wine Valley & Departure
Close the trip along the Moselle, Luxembourg’s wine river, tasting the Crémant and dry Rieslings that rarely leave the country before riding the free bus back to the airport.
🚌 Transfer — Echternach to Grevenmacher
≈35 min · €0 (free public bus)
The bus drops south from the Mullerthal plateau to the Moselle River, which forms the natural border with Germany for the whole of the valley. Grevenmacher’s riverside promenade is a pleasant five-minute walk from the stop.
🍷 Caves Bernard-Massard
1 hr tour · €9/person incl. tasting
Luxembourg’s best-known Crémant producer has been aging sparkling wine in these limestone cellars beneath Grevenmacher since 1921, using the same méthode traditionnelle as Champagne. The self-guided tour winds past riddling racks stacked with thousands of bottles before ending at the tasting counter upstairs.
Caves Bernard-Massard · +352 75 05 45 · bernard-massard.lu
🍇 Domaine Sunnen-Hoffmann, Remich
≈20 min south · tastings from €18/flight
A short hop downriver to Remich, this family-run estate farms south-facing Moselle slopes for crisp dry Rieslings, Pinot Gris and Crémant, and pours flights in a modern tasting room built into the vineyard itself. It’s a quieter, more personal stop than the big Grevenmacher cellars — worth the extra half-hour before heading back to the city.
Domaine Sunnen-Hoffmann · +352 23 69 81 46 · sunnen-hoffmann.lu
✈️ Transfer to Luxembourg Airport
≈40 min · €0 (free public bus)
The free regional bus runs from Remich back to Luxembourg City, connecting directly to the airport shuttle for your flight home — the fifth straight day of moving around an entire country without paying a single transport fare.
