Roc de la tour is a unique rock formation and a natural viewpoint in the French Ardennes close to Belgium, situated at an altitude of 400 metres in the Château-Regnault forest. In spring it’s more green, but even in autumn it’s a great climbing spot. As it is close to the Semois river, you can enjoy many hiking tours in green nature close to the towns Monthermé, Tournavaux, Les hautes-rivières and even Vresse-sur-Semois in Belgium.
