The Belgian Ardennes, from the Meuse to the High Fens

Citadels above the Meuse, the loops of the Semois, caves and the High Fens plateau. A five-day loop from Namur, through the forests of southern and eastern Wallonia.

The Belgian Ardennes, from valley to valley

The best way to see the Belgian Ardennes is to follow their rivers. From Namur, the road runs along the Meuse at the foot of limestone cliffs to Dinant, with its collegiate church and its citadel. Just past the town, it squeezes between the cliff and the Rocher Bayard, a rock needle about forty metres high. Legend has it that the horse Bayard split it with a kick of his hoof. Further on, the pointed towers of Vêves Castle look down on the village of Celles.

Then the road enters the forest. At Han-sur-Lesse, the Lesse disappears underground and comes out again at the far end of the caves. Further south, the Semois winds in wide loops between wooded hills. You look down on them from the Rochehaut viewpoint or from the one at the Tombeau du Géant.

To the east, you pass the Coo waterfall and the Spa-Francorchamps circuit, then climb onto the High Fens plateau, a moorland of peat bogs. Here the Signal de Botrange marks the highest point in Belgium, at 694 metres. The loop returns to Namur by way of Spa and Durbuy.

Bouillon and the Semois valley

Bouillon Castle stands on a rocky spur, in a loop of the Semois. Its keep was built between 1080 and 1090. The castle owes its fame to Godfrey of Bouillon. To pay for his departure on the First Crusade, in 1096, he pledged it to the Bishop of Liège. He died in Jerusalem in 1100, without ever coming back. Today you explore a maze of halls, underground passages and courtyards, with the town and the river below.

Downstream, the valley long lived off tobacco, introduced in 1855 by a schoolteacher, Joseph Pierret. Cultivation declined after the 1950s, and the last commercial production stopped at the end of 2025. At Vresse-sur-Semois and Laforêt, long wooden drying sheds remain, where the leaves were air-dried.

Since 2022, the valley has been a national park. When the water level allows, you can paddle down the river by kayak.

Bastogne held out until Patton’s tanks arrived on 26 December.

The Battle of the Bulge

On 16 December 1944, the German army launched a last offensive through the Ardennes. The next day, at the Baugnez crossroads near Malmedy, American prisoners were shot. Bastogne, a road hub, was surrounded on 21 December. Called on to surrender, General McAuliffe replied with a single word: “Nuts!”. Bastogne held out until Patton’s tanks arrived on 26 December. Further north, Malmedy was bombed by American aircraft on 23, 24 and 25 December: more than 200 civilians were killed. The offensive was pushed back by the end of January 1945.

The region still bears the marks. In Bastogne, the Mardasson Memorial, unveiled in 1950, is shaped like a star and bears the names of all the American states. Right next to it, the Bastogne War Museum, opened in 2014, tells the story of the battle.

The church of Orval Abbey, its large carved Virgin and the pool.

Orval Abbey

Florenville, Wallonia · 40 minutes from Bouillon

The ruins of the Cistercian abbey, burnt down in 1793, stand next to the abbey rebuilt from 1926. Legend has it that a trout brought back the ring Countess Matilda had lost in the spring. The brewery is not open to visitors.

Practical notes

When to go
May to October. Autumn colours the forests and opens the game season. In winter, several sites cut their opening hours.
Getting there
Namur is an hour from Brussels and just over three hours from Paris. No tolls and no vignette in Belgium.
Access
Everything is tarmac. The Semois roads are narrow; the descent from Rochehaut to Frahan is not advised for large vans.
Sleeping in a van
Plenty of campsites along the Semois, the Lesse and the Ourthe. Wild camping is banned in the forests and in the High Fens.
Worth knowing
The Han caves tram has not run since early 2026: check access on the caves’ official website. After the fire of August 2026, some areas of the High Fens may be closed: ask at Botrange.
Allow
Five days for the loop, plus half a day for Orval Abbey.

Food in the Ardennes

Ardennes ham, salted and often smoked, has had protected geographical indication status since 1996. In autumn, restaurants serve game from the nearby forests, wild boar and roe deer.

In Dinant, the couque is a biscuit of honey and flour pressed into carved wooden moulds, so hard that you break it into pieces. The abbeys of Rochefort and Orval brew Trappist beers, under the monks’ supervision.
