The Best Rainy Day Activities in Brussels
Brussels gets rain year-round, but a wet day here is far from a wasted one. The city packs in some of Europe's finest museums, covered galleries, breweries, and atmospheric indoor spaces that reward slow exploration whatever the weather.
Brussels receives rainfall in every month of the year, so having a strong indoor plan isn't just useful — it's essential. Fortunately, the city is extraordinarily well-equipped for exactly this. The museum scene alone could fill several rainy days without repetition, and that's before you factor in covered arcades, historic breweries, and underground archaeological sites. Whether you're arriving for the first time or know Brussels well, the attractions below give you the best possible wet-day itinerary. For a broader picture of the city's indoor and outdoor offerings, see our guide to things to do in Brussels. Most major museums cluster in the Royal Quarter and the European Quarter, making it easy to combine two or three in a single day. Note that many institutions close on Mondays, so check opening hours before you head out.
💡 Local tip
Most Brussels museums close on Mondays. The Art & History Museum opens Tuesday–Friday from 9:30 to 17:00 and on weekends from 10:00 to 17:00. The Brussels City Museum opens Tuesday–Sunday from 10:00. Always verify hours on the official website before visiting.
World-Class Art & History Museums
The Royal Quarter is the densest concentration of serious museum-going in Brussels. You can spend a full rainy day moving between the Royal Museums of Fine Arts, the Magritte Museum, and the Museum of Musical Instruments without ever stepping outside for more than a few minutes. Each institution stands on its own terms, so pick based on your interests rather than trying to squeeze in all three at once.
1. Spend Hours Inside Bruegel and Magritte's World
A vast complex covering Belgian art from the 15th century to the present. The Old Masters Museum holds Bruegel and Rubens; the Fin-de-Siècle Museum traces Symbolism and Art Nouveau. Budget at least two hours — most people need three.

FAQ
Which Brussels museums are free to enter?
The House of European History and the Parlamentarium are both free. The Royal Museums of Fine Arts offer specific free-entry times that can change, so check the museum’s official website for the current first-Wednesday policy before planning around it. Many Brussels city museums offer reduced or free entry to under-18s and EU students — check each museum's official website for current terms.
Are Brussels museums open on Mondays?
Many are not. The Royal Museums of Fine Arts, Magritte Museum, Art & History Museum, Brussels City Museum, and BELvue Museum all close on Mondays. Some newer venues such as ADAM Design Museum or Belgian Beer World may be open on Mondays, but their schedules can change. Always check the official website of each venue before visiting.
What's the best area to be based for rainy-day museum-hopping?
The Royal Quarter (around Place Royale) gives you the Royal Museums of Fine Arts, Magritte Museum, and Museum of Musical Instruments within a five-minute walk of each other. The Cinquantenaire in the European Quarter clusters the Art & History Museum, Autoworld, and Military History Museum together. Both areas are easily reached by metro.
Is the Galeries Royales Saint-Hubert good for a rainy day?
Yes, it's one of the best options in the city centre. The 1847 glass-vaulted arcade is fully covered, houses excellent chocolate shops, cafés, and a bookshop, and connects directly to streets near the Grand-Place. It's not a museum, but it's a genuinely beautiful space to spend an hour browsing without getting wet.
How many rainy-day activities can I realistically do in one day in Brussels?
Two substantial museums plus one shorter stop (a brewery tour, the Galeries, or an underground site like Coudenberg) is a comfortable full-day itinerary. Major institutions like the Royal Museums of Fine Arts or the Art & History Museum each warrant two to three hours alone. Trying to visit more than three significant venues in a single day leads to fatigue and rushed viewing.
