Brussels is full of kids-friendly museums: impressive collections, playful staging, and often enough to easily occupy 1h30 to 2 hours indoors. Some ideas tested and approved by the family:
- Comic Strip Museum – For fans of Tintin, Spirou and company.
A nice outing from 4–5 years old, even more fun if your children already know some characters. - Choco-Story – A gourmet tour around Belgian chocolate.
Interesting for the whole family; Bonus: it smells good and we’re dry! - Train World – Impressive locomotives and modern scenography.
Allow 1h30 with the family, very popular with 6-12 year olds. - Autoworld – The Automobile Museum in Brussels.
Car enthusiasts (young and old) will love it. - French Fries Museum – Playful and original, ideal for a light and fun outing.

🎭 Immersive activities
Fancy an outing that is different from the classic museum, while remaining well sheltered ? Brussels offers several permanent or long-term immersive experiences: optical illusions, sensory paths, 360° projections, light shows, etc. Among our ideas to try on a rainy day:
- WOM – World of Mind – A great journey of illusions and magic: room of mirrors, vortexes, overturned rooms, interactive installations… Ideal from 6–7 years old.
- SENSAS Brussels – A sensory journey in teams, often in the dark, with challenges to be met: perfect for pre-teens and teenagers (from 7 years old).
- MOIR – Museum of Infinite Realities – A virtual and introspective museum, a stone’s throw from the Grand-Place, with an interactive tour to get to know each other better. Rather for older children / teenagers.
- Museums of Illusion – Optical illusions, “impossible” pieces, trompe l’oeil for photos… Great idea for a family outing on rainy days.
And of course, you will also find below the perfect temporary immersive exhibitions of the moment if you come to Brussels for a weekend.

❓ Frequently Asked Questions – What to do in Brussels when it rains?
On rainy days, bet on 100% indoor activities: fun museums (Natural Sciences, Comics, Train World, French Fries Museum, etc.), immersive experiences (WOM, SENSAS, MOIR, temporary immersive exhibitions) and indoor or mostly covered guided tours. These are outings that work just as well with tourist families as with Brussels residents.
Yes, teenagers love immersive experiences, sensory journeys (such as SENSAS), interactive museums and guided tours that are “out of the ordinary” (investigations, dark stories, street art…). These are good options to get them moving without feeling like you’re “dragging them through a museum”.
On rainy days, especially on weekends or during school holidays, indoor activities fill up very quickly. It is strongly advised to book online as soon as you know your niche. For families, it avoids queues with children.
Most museums and immersive experiences allow you to stay between 1 and 2 hours on site, which is ideal with children. Beyond that, they get tired, especially when it’s dark or there’s a lot of noise. Also plan some time for travel, the locker, the shop, etc.
More and more places in Brussels are accessible to people with reduced mobility and strollers (lifts, ramps, adapted toilets). But this is not systematic: it is better to check the practical information before booking, especially for immersive experiences in the basement or in old buildings.
Absolutely: most of the experiences and museums can be rediscovered very well even if you live in Brussels. It’s a great idea to vary the classics (cinema, shopping mall) and keep the kids busy on rainy weekends without necessarily leaving the city.
