The impressive Bouillon Castle towers high above the Semois and is one of the best-preserved medieval castles in Belgium. With its massive walls, secret passages, and spectacular views over the valley, it feels like stepping back in time. An absolute eye-catcher during any hike in Bouillon.

A beautiful stretch along the water, the route is easy to do with a dog. (We had a shepherd.)

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)

From this bridge you have a beautiful view of the Semois on both sides.

The fortified castle of Bouillon is situated on three rocky ridges and offers stunning views of the city. During your visit, you can also take in a falconry performance. Falconry was a true art form during the Middle Ages. You can conclude your visit with the Scriptura Museum, which chronicles the history of education, and the exhibition of the fresco "The Armed Pilgrimage of Godfrey of Bouillon." The castle is open daily.

You can walk along the water here, but this is a pressure point.
