The reserve is located in the far north-east of the country and is bisected by the Walewale–Gambaga–Nalerigu road. The topography is hilly with a sharp escarpment running north-eastwards for several kilometres, to the village of Nakpanduri and extending eastwards to the border with Togo. The vegetation is a mixture of open Guinea Savanna woodland intergrading to Sudan Savanna, with trees reaching 10–12 m. The soil is generally sandy interspersed with large boulders.
