Start of the Voie Verte de l'Avesnois

Located in the Avesnois Regional Natural Park, the Avesnois greenway connects Trélon with Ferrière-la-Grande in the north via Liessies, Solre-le-Château, Lez-Fontaines, Sars-Poteries and Dimont. Along the way, you will discover the landscapes of the Abbé-Val-Joly state forest, the Helpe Majeure valley and the Solre basin. A varied route between nature and heritage.
The Voie Verte de l'Avesnois (Emerald Trail) uses approximately 30 km of the old railway line that opened in 1885 and connected Maubeuge to Fourmies. Closed to passengers in 1969 and to goods in 1976, it is still used occasionally for freight on the Maubeuge-Ferrière-la-Grande and Trélon-Fourmies sections.

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