Traffic-free bike rides around Bouillon
The most famous representative of the dynasty, Godfrey of Bouillon (Duke of Lower Lorraine, c. 1060 to 1100), takes us back in time to the late 11th century. Geographically, however, the life story of this man takes us far from his homeland: across the Mediterranean to the Holy Land. He participated as a leading figure in the First Crusade and the conquest of Jerusalem. After the city's capture, he was to become king of the Crusader Kingdom of Jerusalem, but he rejected such a title, arguing that the only king over Jerusalem could be Christ himself, who was crucified and buried here—and resurrected.

This beautiful suspension bridge is 55 meters long and is located at the intersection of several hiking trails. The Moulin de l’Épine footbridge was built to connect hikes from Botassart and Corbion. The bridge only opened in 2020 after years of legal wrangling. A wooden watchtower stands on both banks of the Semois River. The Moulin de l’Épine footbridge consists of 22 galvanized steel elements with wooden planks held up by two strong cables. The bridge wobbles and sways quite a bit when hikers walk across it, but is otherwise as safe as can be. (TravelValley)

The "Conques" viaduct is located 1 km from the village center of Herbeumont. Construction of the viaduct began in 1902 by the Chagnaud and Cox companies. The viaduct was the first completed structure for railway line 163a. It took two years to build and is said to have used 9 million bricks. The brick construction of graceful, high arches, the central one reaching almost 40 meters above the Semois, is truly impressive. Although construction was completed in 1904, it would be another 10 years before the first trains (under German occupation) rolled over the viaduct! (Trails and hikes)

When we were there (early June) the view was largely obstructed by the bushes… a shame, but it remains a beautiful spot.
