In other destinations, the day-trips are usually considered a “plus” and only recommend if you have extra time, however, in Belgium there are some cities that are as important as Brussels.
To do these day trips we recommend spending the night in Brussels and taking an early train or bus to the city of interest. Since the following towns are so close to Brussels and are all relatively small, you’ll only need one day to explore them. Moreover, hotels are generally more expensive outside Brussels.
A little further away, 177 miles (285 km) to the south east of Brussels, is Paris. Belgium’s capital is connected to this city by the Thalys train. This high speed train takes 1:20 hours to get to the capital of France.
