Enjoy a travel through time aboard this authentic steam train, a wonderful way to discover the Viroin and Haute-Meuse valleys in Wallonia.

The steam railway of the three valleys or CFV3V goes from Mariembourg to Treignes, via  Nismes, Olloy-sur-Viroin and Vierves, the latter being listed as one of the prettiest villages in Wallonia. You are sure to fall under the charm of the picturesque landscapes along the way.

You can learn more about this network, famous in Europe for its beauty at the Musée du Chemin de Fer à Vapeur des Trois Vallées.
