What to do when it rains in Luxembourg? 6 family outing ideas

It’s raining… 🌧️ The trip to the park is a washout, the walk is postponed and the picnic will have to wait for better days. But there’s no question of letting the kids mope around at home! We’ve found 6 ideas for family outings in Luxembourg when it rains: museums, immersive experiences, games and discoveries… Sheltered from the rain, but not from boredom! 😎

Well, there you have it, just our luck, the rain is joining the programme. Goodbye outdoor outings, hello indoor activities! And all the better, because we’ve found a place where your kids can play grown-up for a whole day.

Head to City Concorde in Bertrange to discover SPILLY, Luxembourg’s first immersive indoor mini-city! Spanning more than 700 m², children aged 0 to 11 can explore a real little world designed especially for them.

Firefighter, doctor, pilot, baker… they choose their profession, put on their costume and get to work. Here, there are no rides or screens: they learn through play, make up stories and let their creativity do the work 👨‍⚕️✈️

A lovely way to develop independence, self-confidence and imagination, while having a great time like little rascals 😏

📍 City Concorde, Bertrange - LU

Tired of museums where the phrase “Don’t touch!” comes up every three minutes? Head to PLOMM, the Children’s Museum in Wiltz, where little explorers aged 0 to 12 are the ones in charge.

Here, there’s no question of standing obediently in front of display cases: you touch, test, create, climb and, above all, imagine. With interactive exhibitions, creative workshops and experiences to share, every corner of the museum invites children to become active participants in their discoveries.

And the star of the place is undoubtedly the Story Tree 🌳. Standing 7 metres tall, it hides a maze in its roots and a nest perched in its crown. Plenty of opportunities to climb, explore and live a thousand adventures.

This summer, the On the Move! exhibition invites children to explore the different ways of travelling: with their bodies, their ideas, materials or simply their imagination. And with the LOVE exhibition, they can also discover the thousand and one ways of talking about love, through emotions, creativity and little everyday stories. Exactly what it takes to turn a rainy day into a great adventure ☔✨

📍 2b Avenue de la Gare, Wiltz - LU

Is it raining outside? Perfect, we were just planning to lock you up. Head to Prison Island Luxembourg, the country’s first action game, located in Bonnevoie!

Here, there are no padlocks to open for 45 minutes: 28 cells, 28 challenges and zero clues. It’s up to you to put your brainpower, agility, precision and, above all, your team spirit to work to collect as many points as possible 😏

Some cells put your muscles to the test, while others challenge your logic or coordination. And with several difficulty levels, you can come back and try your luck without playing exactly the same game again.

Accessible from age 8 (accompanied by an adult), Prison Island is played in teams of 2 to 5 players!

And right now, until September 13, take advantage of their summer offer: on Tuesdays and Thursdays, 1.5 hours of play for the price of 1 hour! Enough to extend your sentence… without increasing the bill 😏 

📍 34 Rangwee, Luxembourg - LU

If the weather has convinced you that the sofa is your best friend for the day, we might have a better idea. Head to the Luxembourg Science Center in Differdange.

At this interactive discovery center, you touch, test, handle and experiment. More than 100 interactive stations are waiting for you. You can lift a car with the strength of your arms, challenge a robot at foosball or discover the world’s largest plasma ball ⚡

And if you want to take the experience even further, it’s time for the 20 Science Shows, accessible from age 6. Electricity, fluids, optics, magnetism, acoustics… Science becomes a real spectacle before your eyes.

A perfect outing for rainy days, where kids can let off steam while getting their neurons working. And honestly, if learning were always this fun, perhaps we would all have been top of the class 🧠

📍 1 Rue John Ernest Dolibois, Differdange - LU

It’s raining outside and you’re stuck at home with a bunch of overexcited kids? We have an idea: lock them up. Well… figuratively speaking! 😂

Take them to CROCUS Escape Room in Luxembourg! For 60 minutes, your tribe will have to observe, search, think and solve puzzles to complete their mission. Here, everyone can contribute their own little idea: the kids with their overflowing imagination, the parents with… their life experience (well, normally) 😏

Several adventures are on the programme: a Casa de Papel-style heist, tourists stranded in the middle of nowhere or a magical getaway to Hogwarts (if you can find Platform 9¾, of course 🪄). It’s up to you to search, think, communicate and outsmart the traps before the timer signals the end.

CROCUS also offers free-roaming virtual reality games . Zombies, parallel worlds and total immersion: perfect for those who think an escape game isn’t intense enough yet 🧟

📍 14 Rue Robert Stumper, Luxembourg - LU

Looking for a dry outing when the weather decides to do whatever it wants? Head to the National Museum of Natural History of Luxembourg, in the heart of the Grund, to discover animals, nature, evolution and little mysteries of our planet. And some of the creatures are so realistic that you almost expect to see them move… 👀

In addition to the exhibitions, you can enjoy the planetarium, workshops, gardens and numerous activities to discover science in a different way 🌌

🎉 GREAT DEAL: NATURMUSÉE-FEST 2026!
