Mostly good and smooth asphalt with little traffic (unless there are lots of tourist SUVs and buses driving through).
Beautiful route with some climbs and descents, all of which are also doable for beginners with mostly 8-10%, sometimes up to 13%. The actual climb goes north.
You can also find more information about the tourist highlight in the north under the name Grand Cascade de Tamghaza (although "Grand" is very relative), the great gorge is interesting, less so the waterfall (cascade)
