The Harchies marshes, in the Hainaut, are wetlands of ornithological interest. This nature space offers one of the most diverse flora in Wallonia.

Located by the Musée de l’iguanodon de Bernissart, these 550 hectares are manged by the CRIE (Centre régional d'initation à l'environnement or Regional centre focusing on nature awareness). Its mission? Preserve this exceptionally rare area.


Mining led to collapses of the surface and subsoil in places. In time, the ground level water rose, creating these wetlands covering 125 hectares of the site.

What to do

  • Take a guided tour to learn more about the reed beds, a natural habitat (sadly getting rarer these days) for migrating birds
  • Use your binoculars to get a glimpse of the local fauna
  • Try one of the 2 routes on site (4.8 and 6.7 km)
