Eau Noire (rivière) - Belgique 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.

This route takes you up to the Croix de la Roche in Lomme, where you can enjoy a magnificent view of Nismes. This limestone peak topped with a cross offers a unique view of the Viroin valley. La Roche à Lomme is known beyond its borders for its great biological value. The rocky slope to the south-east is covered with Mediterranean-style flora, enhanced by the abundant presence of boxwood.
