The best places to visit in Luxembourg, ranked

Luxembourg is deceptive. A country 82 km from top to bottom manages to hold a fortified capital, more than 70 castles, sandstone gorges and a valley of vineyards. This isn’t a list of everything there is. It’s what I’d put in front of someone coming for the first time, with a score and a reason for every place.

The capital comes first, and deserves to

Luxembourg City grew from a rocky spur wrapped by the Alzette in 963, and for centuries it was one of the great fortresses of Europe. What survives is an old town clinging to the cliff and a lower district, the Grund, down by the river. UNESCO listed the old quarters and fortifications in 1994, and that’s why the old town tops my list at 9.6.

I’d start on the Chemin de la Corniche, the rampart walk between the Bock and the Citadelle, and then drop down into the Grund. The Bock Casemates earn their 9.2 even with a guided tour to pay for, because going into the tunnels that held the fortress together changes how you see the city from above. In between you’ll pass the Grand Ducal Palace, open only in summer, and Notre-Dame Cathedral, which is free.

The castles I’d actually pay for

Of Luxembourg’s 70-plus castles, only a handful let you inside, and that’s where you need to choose. Vianden Castle is the most complete, with restored halls and the view over the Our valley, which is why it gets 9.3. In October it opens from 10:00 to 17:00 and an adult ticket is €13.

Bourscheid is a different animal. Its eleven towers stand 150 m above the Sûre and the visit feels more like a ruin than a palace, which I rather like. Clervaux is on the list for what’s inside, The Family of Man photography exhibition, and Beaufort closes it because it pairs so well with a walk. The full ranking, including the ones you can only see from outside, is in castles in Luxembourg.

Rocks, a waterfall and a lake you can swim in

The Mullerthal, nicknamed Little Switzerland, is for me the biggest surprise in the country. Think sandstone forest with narrow passages between the rocks, wooden ladders and the Wolfsschlucht, a gorge 40 m deep. The Mullerthal Trail adds up to 112 km in three loops, and you don’t need to walk them end to end. A half-day stretch from Echternach or Berdorf is plenty to get the idea.

Up north, the Upper Sûre lake covers around 380 hectares behind a dam built in 1961. It’s the largest body of water in the country, supplies drinking water to roughly 70% of the population and has designated swimming areas in summer. Esch-sur-Sûre, with its ruined castle, sits right beside it.

Is the Moselle worth it if you don’t drink wine?

Less so, honestly, which is why it’s in tenth place. Remich has a 3 km promenade under lime and cherry trees and boats leave from the quay, but what makes the Moselle special is the wine, with 1,189 hectares of vines in 2025 and crémant as its calling card. If that’s not for you, I’d spend the half day in the old mining south instead, at the Belval blast furnaces, where €5 gets you up to a platform 40 m above the ground.

What didn’t make the cut

The Grand Ducal Palace is the obvious gap, and the reason is the calendar. In 2026 it opened only from 18 July to 30 August, for 75-minute guided tours that sold out, and there’s no word yet on 2027. If they line up with your trip, book the moment they appear. I’ve also left out the Kirchberg, with Mudam and the Philharmonie, because it’s more about contemporary architecture than a first visit.

Fitting the list into your days

One day, the capital. Two days, the capital plus a castle up north. Three or four, add the Mullerthal and the Moselle. Public transport is free and reaches all of these, so you don’t need a car, although for Bourscheid or the Upper Sûre lake one saves time. If you’re planning several paid visits, price it against the LuxembourgPass, which covers 81 attractions.

When you’re after activities rather than sights, they’re in things to do in Luxembourg, and if it’s photographs you’re travelling for, my pick is in the most beautiful places in Luxembourg. The whole country, with its regions, transport and where to stay, is pulled together in my Luxembourg travel guide.

If you would rather have a local show you round, book a guided tour in Luxembourg and choose by the reviews.

A car frees you from timetables: search car hire in Luxembourg on DiscoverCars and compare companies.
