La grotte de Nichet

The Ardennes conceals treasures right down to the bowels of the earth. The cave of Nichet is one of them. Naturally dug into the limestone of the Ardennes massif, it reveals to the visitor the mysterious forms with which nature has endowed it.
The Nichet cave is also the refuge of nutons, these small beings endowed with powers that can sometimes be encountered during a walk in the Ardennes forest.
Located in Fromelennes, the Nichet cave is an invitation for an imaginary escapade to the center of the Earth. This natural site, dug into the limestone, inspired popular mythology. During your visit, you will sink more than thirty meters into the “bowels of the Earth”, and will come across small inhabitants known as Nutons. You will also discover numerous rooms (the Moonlight Room, the Lion Gallery, etc.) spread over three levels. Added to this, an atmosphere with light and sound effects (tour in three languages) which accompany the explanations given by your guide. Tour in three languages. Exploited since 1895, the cave was reopened to the public in 1987. This cave has retained its original character and forms, incontestably, the most charming geological curiosity of the Ardennes.
