L'étang de la Conge

Created by sand extraction in the 1960s, part of this quarry is now open to the public on municipal land. An educational trail offers visitors the chance to discover some of the original natural environments to be found near the Castelle urban area: ponds, reedbeds, wet meadows, ponds, flooded woodland, populated by various species of orchid (Spotted Orchid), dragonflies, amphibians (Red Frog), birds and the Marsh Fern.
