Église Saint-Lambert (Nismes) walks

Over millions of years, the action of water has carved huge chasms up to 20 metres deep into the limestone. These natural chasms are called "Fondrys". In Belgium, they are only found in the Viroin region. Discover geological curiosities and viewpoints. Explore beautiful landscapes combining rocks, rivers and limestone grasslands where numerous orchids appear in spring.

Standing on a rock, you look out over the natural chasm of Fondry des Chiens. The limestone soil of the region gives this place an otherworldly feel and takes you on a journey without leaving the country. Who said you had to go far away to get a change of scenery? Hike without description, to be followed on the Visorando app.
