Our corner of Wallonia lies in the valley of a small river – the Rau de Vieux Fourneau – which tumbles into the larger river Aisne, which is in turn a tributary of Belgium’s second longest river, the Ourthe. For tourism purposes, the immediate surroundings are trademarked as Le Pays d'Ourthe & Aisne. We are in the Famenne region – or, geologically speaking, the “Calestienne”. This is an area of limestone known for its deep and giant caves carved out over millions of years, and adorned with enormous stalagmites and stalactites. Several of the caves are open to the public, including that of Remouchamp with its breath-taking subterranean gondola trip along the Rubicon river (not Julius Caesar’s Rubicon, but you can cross it nonetheless). Above ground there’s a varied landscape of bucolic beauty. The sombre, conifer hillsides of the Ardennes lie further to the south. Here, a mix of evergreen and broad-leaf trees is evenly balanced with pasture and hedgerows. Jagged teeth of rock stand like sentinels in mossy fairy-tale forests of pine, oak, beech and hornbeam. Cliffs overhang meadows and rivers and tumbling streams.
