Morocco for some reason does not have nearly enough bridges. To that end, be safe and pay attention to the weather forecasts and be warned that roads frequently flood over and make sections impossible.
Delays can last up to several hours after the storms stop, so you should have some basics in the car (water, etc.) to make any delay a bit more comfortable. If you don't know how your vehicle handles in high and/or fast moving water, don't even try it.
This is just a pointer that the road heading on up to the Dades Gorges follows a winding river that has created a fertile and lush oasis belt and therefore a lot of people do live and work along this route.
This makes the road a major access road and is trafficked by all sorts and not just cars to look out for - children making their way home from school, women carrying huge loads of vegetation to take home for their animals after a day in the fields, cyclists and vehicles of all sorts including donkeys
- and to stress that many people here do not have much or any road sense as well as people who are tired and not really thinking that they should be looking out for the car driver but the
other way around.
So take care when driving - rarely does one see use of illuminated gear and pedestrians do seem to meander all over the road as they socialise with each other!
The road can be quite potholed in places from time to time too. and take care for rocks that may be strewn across the road from the eroded and crumbling hillsides along the road ways.
as well as livestock such as donkeys that may just cross the road or just stand out in the middle of the road.
If you see a stack of rocks or stones, especially on the side of the road, this is the locals way of making a marker or warning sign of something to watch out for - eg a section of the roadside might have washed away
Leaving Ouarzazate it was blue skies and sunshine, as it was until we approached the Dades Gorge, when a thunderstorm with torrential rain blew up.
Rainfall can dislodge the rocks and soil from the Gorges cliff sides, resulting in rockfall and mud on the roads.
This resulted in a curtailed visit, and our 4X4 skidding on the way out of the gorge! This was in early September.
So if venturing up here, be sure that you have a good vehicle, and keep an eye on the weather.
