We were there the other week in a rental Duster.
Tarmac currently ends 61km west of Lab, then a thin, unprepared trail with a couple of junctions for a few kms, then picks up and becomes a normal piste via the valley drop (below) to meet new tar a few km south of Mseid.
I traced the route off Google/Bing sat.
Tbh, MW6 is more scenically diverse, but on the way we visited the rock art at
27.85183, -10.65733 and only a couple of good km off the main piste.
Very good Mk prehistory resource by Gandini.
Interesting chat with the bright young bloke who has been left to guard the fenced off site.
Not seen 'Tassili' style paintings like this anywhere else in southern Mk, but Gandini link IDs more.
We carried on SW to 'red sign jct' on the R101 Tan Tan–Smara road south of Abteh and on to Cheap Fuel Junction.
Not that interesting and some tricky route finding across the big oued.
We then took an excursion to the tomb complex of Sidi Ahmed Rguibi in the middle of nowhere.
Ancestral father of the Reguibat Saharawi.
Warm welcome but matey called someone and access denied.
Despite what the internet claims, '1000s' of pilgrims no longer (if ever) visit the site.
Back on the Gandini page I was trying to find this amazing looking place near Oued Chbika, even though I know these massive tombs never look as good from ground level.
Could not find it until I worked out that since that image was shot from a plane about 20 years ago the place has become a quarry for wind farm installations and capped off by a pylon pathway. One antenna remains under a pylon.
