Ag Oua–Ag Arbech lies north-north-east of the town of Gao in the east of the country. Provisional boundaries for the site are as follows; the Niger river from opposite the village of Aguinaouiaoui north along the river to opposite Doumbaria-ou-Echak, north-east to Amakouladji on the Gao–Bourem road, continuing in the same direction to 16°40’N 00°00’W, then due east to 00°17’E, turning due south to meet the course of the wadi running through In Chaouag, following the course of the wadi south-east until it reaches the road from Gao to Almoustarat, and from there to Aguinaouiaoui. This area includes part of the ancient watercourse of the Tilemsi valley, open desert, dunes, rocky outcrops and mixed cultivation together, with scattered shrubs and trees along the Niger river.
