The island has an area of 32 ha. The coastline comprises granite boulders and slabs, with a steep rise of about 5 m to a flat calcarenite plateau covered with sandy soil which supports Nitre bushes (Nitraria billardierei) and African boxthorn bushes (Lycium ferocissimum). There are small caves and overhangs among limestone cliffs immediately inland of the granite boulders.
