The entrance gate of Meddak Region is located at minimun 16 hours of Hike (32 hours there and back) from Djanet. After Assakao Pass, this is a long way included a large stretch of monotonous flat with "nothing to see" called Reg in Sahara. There are few and light rock arts on the sites of Meddak. It is probably why the author and his Targuia dromedaries caravaner staff found nobody, both local or tourist, during a 20 days trip across the area on october-november 2007. For these reasons, Meddak Region is seldom visited. Also younger guides did not know these ancestral path which occurs on these remote landforms and certainly did not want lost tourists here. My guide Mohamed Bilali aged 68 at the time of this expedition is native of Meddak and know very well these secluded sites. I will be fortunate to have him on the trip and on most of the one I had during nearly a decade on Tassili National Park. The sites visited during the expedition was Tan-Azoulagh, In-Tabakat, Ouan-Saken, Ibouan, Oumrak Canyon, Akchaheré, Emelell and Irekam-In-Tafest. The natural arches included on these pages are probably first reported.
