A short tour in the Avesnes countryside offering beautiful views of Solre-le-Château and its leaning bell tower. Route mainly on asphalt paths with however a grassy path over 600m. Possibility of walking from Lez-Fontaine to the hamlet of l'Epine via the greenway. Ideal departure: the square of Solre-le-Château where parking is easy and where it is possible to eat or refuel.

Very beautiful landscape and very nice asphalted railway line cycle path EV3. It's a shame that it isn't extended a little further.
