Three of the largest cities in Belgium include Antwerp, Ghent, and Brussels, and traveling between the cities is quite easy due to the number of options that are available. For example, there is plenty of train service between all these three cities aboard Belgian Railways, which offers train service between all three of the cities several times perh every day. Another option for traveling between all the cities is to travel by busses operated by FlixBus, which also makes several trips between all of these cities every day. Because the country of Belgium is geographically small, the distance between all of these cities is not that far, so you could even hop into a rideshare car or a taxi to make the trip between all the cities. Of course, one final option, if you prefer to do your own driving, is to rent a car at one of the major airports in the country and then do the driving yourself on the very well-maintained road system that exists in Belgium.
