A southward view of the E411, Belgium's main highway cutting through the Ardennes. Pic taken from the Viaduc de Custinne. In the distance, the blue-green of the Ardennes beckon. Follow this highway another 100 kloms or so and you're in the Grand Duchy of Luxembourg.
The inside of the ruins of the Chateau d'Herbeumont. Sorry, really got no time to elaborate.
A view on the Semois river meandering it's way through the hills. Note: the green sliver in the center is NOT the 'Tombeau du Chevalier'. That's the ridge in lighter green immediately to the right of this one.
A view of a slice of the Semois - the actual river is just beyond the grassy islet in the center of the photo. Photo taken from the finger of land known as the 'Tombeau du Chevalier'. Its more prosaic name is 'Presqu'ile de Boult'.
View of the Ile de Houx in the Meuse river, taken from amidst the ruins of the Chateau de Poilvache.
And finally a pic of the Chateau de Crupet, or rather its donjon surrounded by a moat/pool. Crupet is a lovely, tiny village more or less right between Dinant and Namur.
The photos don't do justice to the day, but may give you an idea of the landscape in much of Belgium's southeast.
