Situated 3.5 kilometres south-east of the Pont de France, the Charlier viewpoint is on the left bank of the Semois, 500 metres from the old Leauwez redoubt, which provided security for Bouillon against an invader from the east. The forest opposite, to the north, is called Buhan. The river has bypassed the loop of the Han du Han and created the island of Locaillou, followed by the island of Stassart, over a distance of one kilometre. The Semois, on the left bank, comes up against a rock which, at a height of 2.5 metres, still bears the mark of the pike pole used by the miquelets (woodcutters), leaning on their wattle and daub, to push back the load of wood and prevent it from smashing against the rock. This is known as the "coup de lime". Downstream, shortly after the Leauwez ford, the Semois flows into the Burnelles stream, which runs before the Grimouty woods. The name comes from its location "behind the monastery", the former church of St-Charles, in the parish of Bouillon. There is not the slightest trace of habitation in the landscape, nothing but the Semois and the mixed deciduous and coniferous forest, a few traces of meadows on the distant horizon, and everywhere the silence conducive to meditation, interrupted by birdsong, enlivened by the flight of herons and buzzards.
