Carrière de Ligny-Plage is an old pebble quarry in the Belgian province of Namur, now serving as a fishing and diving site. Underwater are numerous old tools that remind of the original purpose of this quarry. Between 0 and 9 metres you have good to very good visibility in Carrière de Ligny. Below 9 metres, visibility quickly drops to half a metre. You can't just dive here. You must first ask permission from the fishing association.
