The first part of the W3 long-distance route immerses you in what was, in the 20th century, Belgium’s biggest iron and steel centre. From Tubize, you head south along the RAVeL that borders the Charleroi–Brussels canal, the Charleroi–Brussels historical canal and a short stretch of the Canal du Centre. Having crossed the city of wolves, La Louvière, a daughter of industry, the Line 422 RAVeL takes you gradually into rural settings.
