The walk leaves from the hamlet of Hourpes, which is where the blast furnaces were once operated and is a site worth visiting. Founded in the 17th century, the site is linked to the infancy of the metallurgical industry in Entre-Sambre-et-Meuse. Its château and workers’ houses seem lost at the heart of the countryside. The walk will take you to the Aulne abbey site where you can relax pleasantly in riverside cafés and restaurants along the water. Walking past the abbey, you can’t miss the magnificent Gothic transept. Return on the RAVeL along the Sambre river where the water level is still regulated by manual locks.
