El Allia lies about halfway between the two main cities in the province, Touggourt and Ouargla. Vegetation (mostly consisting of palm groves in the area) is supported by groundwater, as most of the surface is usually dry. The landscape in the area is a mix of barren rocky plains and sand dunes.
Like other towns in the Sahara, El Allia has a hot desert climate, with very hot summers and mild winters, and little precipitation year-round. Temperatures may reach as high as 50 °C (122 °F) in summer and as low as 6 °C (43 °F) in winter.
