From Florenville the Semois describes a broad curve and meets the through road again at Chassepierre, one of the prettiest villages on the Semois and a popular holiday resort. Slate-roof houses surround the Church of Saint-Martin which has interesting choirstalls, probably from Orval. In the surroundings can be seen caves used by hunters in the
Stone Age and prehistoric dolmens. About 1km beyond the village on the right of the road there is a lookout point with a good view of the village to the rear.
