Withing easy reach of the town centre of Marche-en Famenne, the Fond des Vaulx valley offers wild landscapes: quite a contrast with the wide spaces of the Marche plain.

Fauna, Flora and legends

  • Stretching over 15 hectares, the Fond des Vaulx valley is part of a limestone fringe called Calestienne, modelled millions of years ago by the acidic water of the Ardenne massif, south from there.
  • Legends add to the mysterious atmosphere of the area...
  • A real paradise for nature lovers!

Fantastic walks

There are three paths to explore the area (from 2.2 to 4.5 km):

  • Caves such as the Grotte de la Ducasse, the Trou du Renard...
  • The Trotti-aux-Fosses sinkhole, listed an underground site of scientific interest in Belgium
  • Small depressions and rocks

The ASBL Fond des Vaulx organises guided tours on request.

Fun activities
