À Botassart

A - The Giant’s Tomb

Botassart, a village near Bouillon, is the scene of one of the loveliest, most majestic panoramas in the Ardennes. Here, the Semois makes the most of the relief, constantly winding back and forth. The loop it forms in Botassart is so tight that an island is born in the heart of this green ocean, creating the formidable tomb of a giant said to have been struck down here.

Did you know?

A ford enabled travellers, pedlars or soldiers of the time to cross the Semois and reach Bouillon. Opposite the mill stands the Hermit’s Rock (la Roche de l’Ermite). A hearth created in the rock provided shelter for a hermit-weaver in the late 17th century.

B - Walking

The Mill and the trellis bridge

Walking in the Semois valley when spring comes is delightful! The banks of the river are scattered with thousands of flowers. On the way to the bridge lies the beautiful Mortehan mill: at dawn, its wheel still stirs the waters of the race. Down below, the Semois valley lazily criss-crosses a vast meadow, rich in the river’s alluvial deposits. With the beginnings of warm weather, we can cross the Semois ford on foot, once the only way for the people of the valley’s villages. In season, a trellis bridge is thrown across the water. On the other side, a delightful route ascends the slope. The forest is majestic, as are all the massifs that encircle the Semois.

C - The Fairies’ Castle

Visitors enter the fortress along a corridor. The thick terrace walls command respect. In the Middle Ages, a keep 18 metres high and 13 metres wide dominated this highly strategic location. Encircled by the Munos and Monceux streams, these days it holds out the promise of a lovely walk…

From the fortress, a very pretty walk follows the course of the two streams. (Walking map on sale at the Tourist Office)

Access: The castle is on the Mortehan-Bertrix road.

À Mortehan

D - The old cemetery

It is sometimes difficult to describe the feelings aroused by sites like these. The old cemetery in Mortehan carries visitors into another world. The tombstones bewitch us in the early hours, when vapours rise from the Semois and pervade the area.

Access: The cemetery is hidden from the view of the living. At the little church, follow the road that goes down towards the river. The cemetery lies behind the shale houses.

À Dohan

E - A border rock

A highly strategic place in the Middle Ages. At the time, the castle kept watch over the ford, an alternative for those wishing to avoid the powerful lords of Bouillon.

Did you know?

In the Middle Ages, the ‘Roche Percée’, a natural site where a path runs alongside the river, was the border between the Duchies of Bouillon and Luxembourg, upstream of the mouth of the Alleines stream. The site, which is mentioned in a medieval treaty, also set the boundaries of the bishoprics of Reims, Trêves and Liège.


It is possible to reach the ‘Roche Percée’ following the path that runs along the Semois, just beyond the ‘Poteau de Léveau’. A narrow path from the rock takes you to a splendid panoramic view.
