The Fondry des Chiens in Nismes, also known as the Belgian Grand Canyon, is a natural hollow formed by the seepage of rainwater through the limestone bedrock. It is a unique geological phenomenon and one of the few places in Belgium where you can see such natural gorges. The hollow is approximately 100 metres long and 20 metres deep. The area is surrounded by limestone grassland and dotted with rocks, crevices and caves. The site is rich in rare flowers such as wild orchids and ball daisies, and offers a habitat for various butterflies and lizards. The area is recognised as a nature reserve and is protected because of its vulnerable flora and fauna.

The Fondry des Chiens is a sinkhole in the Viroin-Hermeton Natural Park, located in the municipality of Viroinval, sub-municipality of Nismes, in the Calestienne. This natural phenomenon is a true masterpiece of Mother Nature and has no equal in our country. Over millions of years, water has carved a huge hole in the hard limestone. In some places this hole can be up to 20 meters deep. The rocks in the pit have impossibly soft curves and make it a spectacular sight. Protection: The entire area is integrally protected and is classified as a natural monument. Next to the Fondry des Chiens there is a beautiful calcareous grassland, where thousands of blue flower heads of the rare bollard flower stand out in the spring.

This is untouched nature in the sense that man cannot intervene. Fallen trees remain lying there and every now and then a rock stands in the way, forcing you to climb around and over the rock with the help of ropes and then descend again.

The narrow path winds its way along the shore. Roots and stones lie on the path. The path is somewhat eroded and the water is not far away. At the end of this first part you have to descend a small height difference over a large stone. Spicy!
