Itinerary
Belgium in a Week: Two Countries in One, Two Different Modes
Belgium is small enough that distance is never really the problem — Brussels to the Ardennes is under two hours. The actual planning decision is mode: Flanders runs on frequent, dense rail that makes a car actively unnecessary, while the Ardennes' thinner rail coverage makes a car close to essential. Treating the whole country as one trip with one transport plan wastes whichever half you didn't plan for.

Days 1–3: Flanders, entirely by train
Base in Brussels and treat Bruges, Ghent and Antwerp as day trips — each is under an hour by direct train, frequent enough through the day that no advance booking or fixed timetable planning is needed. A workable three-day split: one full day in Brussels itself (the Grand Place, the EU quarter, Art Nouveau streets), one day trip to Bruges for the canals and medieval centre, one day trip to Ghent for Saint Bavo's Cathedral, with Antwerp added as a fourth day if time allows or swapped in for one of the others. None of this needs a car at any point, and renting one for these three days would only add parking costs and city-driving hassle for no real benefit.
The switch: don't try to day-trip the Ardennes
The temptation is to bolt an Ardennes day onto the same Brussels-based, train-only trip — it's the planning mistake worth flagging loudest. Towns central to an Ardennes visit either lack a train station entirely or sit some distance from one, and a single rushed day trip by train and bus covers barely one site properly. The Ardennes rewards a genuine mode switch: pick up a rental car in Brussels (or at Namur, the practical northern gateway to the region) rather than trying to reach it on the same rail pass that worked perfectly for Flanders.
Days 4–6: the Ardennes, entirely by car
Once the car is picked up, base somewhere central like Namur or La Roche-en-Ardenne rather than commuting back to Brussels each night — the region rewards staying inside it. A workable three-day Ardennes leg: one day at Han-sur-Lesse's caves and wildlife reserve, one day split between Bastogne's war museum and a stop in Durbuy or La Roche-en-Ardenne, one day on the Ourthe or Lesse for kayaking (spring through early autumn) or a Hautes Fagnes moorland hike. This is the inverse of the Flanders days: here the car is what makes the itinerary work at all, not an optional extra.
If you only have four or five days
Pick one half rather than compressing both — a rushed single Ardennes day tacked onto a Flanders trip satisfies neither, and the reverse (a single hurried Flanders city squeezed into an Ardennes-focused car trip) has the same problem in miniature. A four-day Flanders-only trip (Brussels plus three day trips) is genuinely complete on its own terms; a four-day Ardennes-only trip built around one car rental from Brussels is equally complete. The full six-day version above is for a first trip that genuinely wants both halves properly, not a compromise squeeze of either.
