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 first observation tower on the Côte d’Auclin dates back to 1923. A new structure was inaugurated in 2001. The tower stands on a 150m³ concrete base. It has eight floors supported by four wooden pillars surrounded by iron, with a total height of 31.60 m (385 m altitude, or 180 m above the Semois). (InspiRoute)

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