The Tombeau du Géant, a listed Natural Monument, is one of the most famous and most photographed locations in the Belgian Ardennes and the Semois Valley. The most popular viewpoint is near the village of Botassart, about 450 meters as the crow flies from the Semois and about 140 meters above the river.

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)
