The Saracens Cave (or Hole) is located on the right bank of the Fond des Haies stream. There are several entrances, but access is narrow and limited. It is far less impressive than some of the caves in the Ardennes or Namur region, but it still has its charm. The small paths leading to it can be dangerous without sturdy footwear or in wet weather.
