When entering Ouarzazate City, there is the Studio Ecla and a Gas Station. When you reach a roundabout, do not go straight.
Turn right into the way to Tifoultoute Kasbah and when you see the Kasbah, keep going down to cross the bridge.
When you have crossed it, keep going until yu cross another small bridge.
After 100 m from the second bridge, there is a sign of Sarayas which guides you to the place!
