[1] The town of Aoulef lies at an elevation of 288 metres (945 ft) on the eastern side of an oasis.

The oasis is a part of the Tidikelt region of the central Sahara that extends from central eastern Adrar Province (where Aoulef is located) to northeast Tamanrasset Province around In Salah.

The sky is nearly always clear throughout the year and cloudy days are extremely rare.

Aoulef lies on the N52 national highway, which connects it to Reggane and eventually Adrar to the west and In Salah to the east.

A provincial road connects the town to Timokten, located just to the northwest of Aoulef.
