I'm getting confused with 'The Ardennes'...I've been through what I thought was 'The Ardennes' but looking at the map that seemed to be from Givet, due south to Charleville-Mezieres, then due east to Esch-sur-Alzette on the Luxembourg border, but that route was all entirely in France...however most ride blogs about 'The Ardennes' seem to talk about roads and routes entirely in Belgium...?
So I'm not sure if I've been through it or not

(the biking part of The Ardennes, I mean).
Are there any recommendations for a route on the Belgium side...and a town to stay in for a few days?
