Belgium Driving Guide – This guide not only tells you what the best itineraries in Belgium are, but it also means you what you need to know about driving in Belgium from the dos and don’ts on Belgian roads.
BUS > STIB/MIVB in Brussels • De Lijn in Flanders • TEC in Wallonia. Most tourists will not need the bus companies, as it is much more user-friendly to take trains between cities and go on foot inside them. There is also the Kusttram, running along almost the whole Flemish seaside from France to the Netherlands—definitely worth a trip in the summer.
RAIL > Belgiantrain.be – Use the official journey planner operated by the National Railway Company of Belgium to find train itineraries and prices. Thalys • SNCF • Eurostar • Deutsche Bahn
AIRPORTS > Brussels Airport, also known as Zaventem due to the town in which it is mainly located, is Belgium’s main airport. Brussels South Charleroi Airport, about 50 km (31 mi) south of Brussels, mostly serves low-cost carriers.
WATERWAYS > P&O Ferries operate a daily sailing every evening from Hull to Zeebrugge taking 12½ hr for the crossing. DFDS Seaways Ferries operates ferries from Dover to Dunkirk every 2 hr.
