Brussels is small, walkable and full of surprises, but it does not always reveal itself at first glance. The old town around the Grand-Place is compact, the upper town with its museums is a short climb away, and the Atomium and the European quarter are a quick metro ride out. This guide covers what to book ahead, how to get around, how long to stay and how to fit the headline sights into a few easy days.
What to book ahead
Brussels is less booking-heavy than Paris or Amsterdam, but a few tickets are worth securing in advance. The Atomium is the big one: book online to skip the ticket line, especially at weekends and in school holidays. Belgian Beer World and Choco-Story are easy to book a day or two ahead, and a Bruges day trip should be booked a few days in advance, especially in summer and around the festive season. For the Magritte Museum and the Comics Art Museum, buy on the official sites; queues are rarely long, but advance tickets save time. If you plan to see many museums, compare the Brussels Card, which bundles entries and can include public transport.
How to get around
The old town is best on foot, and most first-timers walk everywhere between the Grand-Place, the royal galleries, Manneken-Pis and the Mont des Arts. For longer trips, the STIB metro, trams and buses are efficient; tap a contactless card at the readers or buy a ticket from a machine. Metro line 6 goes to Heysel for the Atomium. From Brussels Airport, trains run to the city's main stations in under half an hour. International trains arrive at Brussels-Midi, which is a short metro or tram ride from the centre. Taxis and ride-hailing apps are available, but rarely needed.
How many days
Two days covers the essentials of the city: one for the old town and upper town, one for the Atomium and a museum or two. Three days lets you add a day trip to Bruges, or Bruges and Ghent together. Four days gives you time to slow down, explore neighbourhoods like Saint-Gilles or the Sablon, and add a second day trip.
Day one: the old town and the upper town
Start early at the Grand-Place, when the square is quiet and the gilding catches the sun. Walk to Manneken-Pis, then stop at Choco-Story for a chocolate demonstration. After lunch, walk through the Galeries Royales Saint-Hubert and climb to the Mont des Arts for the view. Spend the afternoon at the Magritte Museum or the Musical Instruments Museum, finishing with a coffee on the MIM rooftop. In the evening, visit Belgian Beer World in the old stock exchange, then return to the Grand-Place to see it lit up after dinner.
Day two: the Atomium and comics
Take the metro to Heysel in the morning for the Atomium, starting at the top sphere for the view. Families can add Train World in Schaerbeek in the afternoon, a short train ride away. Otherwise, head back to the centre for the Comics Art Museum and follow the comic-strip murals through the streets. End the day in a traditional beer café.
Day three: Bruges
Join a guided day trip to Bruges, or Bruges and Ghent, or take the train independently. Either way, you will see canals, belfries and medieval squares, and be back in Brussels for dinner.
Money and practicalities
Belgium uses the euro, and cards are widely accepted. Tipping is not expected, but rounding up for good service is appreciated. The city is bilingual, French and Dutch, and English is widely spoken. Many museums close one day a week, often Monday, so check before you plan. Watch your pockets in crowded areas around the Grand-Place and the main stations.
When to go
Spring and early autumn are pleasant and less crowded. Summer brings festivals and, in even-numbered years, the flower carpet on the Grand-Place. From late November, the winter festival fills the centre with markets, lights and a skating rink. Rain is possible in any season, so pack an umbrella and keep a museum in reserve.
