As the capital of Belgium, Brussels is a popular destination for tourists, and many EU authorities and related professional events. As a result, there is always high demand for accommodation and delegates are therefore strongly recommended to make flight and hotel reservations well in advance.


Belgium is serviced by most leading airlines operating direct flights from major cities throughout Europe and the rest of the world. The closest airport is the Brussels International Airport.  It is located around 20 minutes away from the city center by taxi; standard fares apply to all Belgium taxi drivers.
