Family hotels in Luxembourg: lakes, rocks and a room of your own

Travelling with children in Luxembourg has an advantage few other countries can match. Everything is close, public transport costs nothing, and there are swimming lakes, rocks to scramble over and castles within a distance a child will put up with in the car. The snag is elsewhere. No official source lists which hotels have family rooms, so I’m leaving names out. What I’ll give you is a way of choosing and the places where there actually is published information.

The option almost nobody considers, the hostel

I’m starting here because I think it’s the best answer for a lot of families. Luxembourg’s youth hostel network publishes its terms in detail. Each family gets its own room, most with their own shower and WC; there are high chairs, cots, board games and drawing materials; bed linen is included and so is breakfast. Ages 3 to 12 pay half, and under-3s pay nothing.

This isn’t a dormitory shared with strangers. And some of them have things a normal hotel doesn’t, like the indoor climbing wall, sports hall and trampolines at Echternach, the bowling lane at Beaufort or the indoor play areas at Beaufort and Lultzhausen. What they don’t have is a guest kitchen, so you eat in their restaurant or out. The full details are in youth hostels in Luxembourg.

Echternach, my base with children

My single pick would be Echternach. The lake on the edge of town covers 30 hectares, with 375 hectares of woodland around it, a footpath round the shore, pedalos and a free swimming area called Adventure Island that opens from 1 May to 30 September, 7am to 10pm. The hostel and the Roman villa are right beside it, and the Mullerthal rocks begin just beyond.

Echternach had six hotels in 2025 according to STATEC, plus three campsites. For the capital, the direct 201 bus leaves every half hour, according to the Mullerthal Trail operator, and costs nothing. Everything is covered in hotels in Echternach.

What about the Upper Sûre lake?

It’s the other big summer option. The Upper Sûre lake is the largest in the country, at about 4 km², with designated swimming areas from 1 May to 30 September. The Lultzhausen hostel sits right on the shore, with a large beach, canoe and kayak hire and an indoor play area for rainy days. Note one rule, in a canoe children aged 5 to 9 need two paying adults in the same boat, which rules out some family combinations. The surroundings are covered in Upper Sûre lake.

The capital with children

For a city break, transport is the trump card. Since March 2020 nobody pays for buses, trams or second-class trains, whatever their age, and that includes the Kirchberg funicular. My advice is to find a hotel next to a tram stop, because with little ones every change you avoid counts.

The city hostel is in the Pfaffenthal, below the Bock promontory, with a reception open 24 hours, which is welcome if you arrive late with sleeping children in tow. Families with a car should know it has its own free car park, a real saving in a city where on-street parking is charged at €0.50 to €2 each hour.

Two traps to avoid

The first is the spa. Mondorf Domaine Thermal is the country’s only thermal spa, but children under 16 can’t go beyond the thermal pool. A spa hotel is not a family plan here, however tempting the photos.

The second is the LuxembourgPass. Plenty of people look for a family rate that doesn’t exist. The official page says the group pass covers 3 to 5 people, related or not, and costs €55 for one day, €66 for two and €71 for three, at the prices published in September 2026. For a family of four visiting several museums and castles, it usually pays off; I explain it in LuxembourgPass.

How I’d split a family week

Two nights in the capital, near the tram. Three in Echternach, with the lake, the rocks and a day out to Vianden and its chairlift. And, if it’s summer, two by the Upper Sûre for the beach and a canoe. More ideas for things to do, rather than where to sleep, are in Luxembourg with kids.

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

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

So you do not pay over the odds, look at trains, coaches and flights to Luxembourg on Omio and pick the one that suits you.
