[3] The town of Reggane and its neighbouring villages lie next to the southernmost oasis of the Tuat region, which stretches northward to Adrar.

The Tidikelt region, a plain with isolated oases, lies to the east, including towns such as In Salah, In Ghar, Aoulef and Tit.

To the west is the sandy Erg Chech desert, while to the south lies the vast barren plain of the Tanezrouft.

The area in the heart of the Algerian Desert bounded by Adrar - Reggane - In Salah is nicknamed the "triangle of fire" by local inhabitants due to the extreme heat that bakes the region from May to September.

The Tanezrouft track is the southern part of Algeria's N6 national highway, which connects to Adrar to the north and Bordj Badji Mokhtar to the south.
