If you are visiting Morocco, you'll probably visit Marrakech. And, once there, you would probably want to see the deep South of Morocco. Then your destination would be Ouarzazate, I guess. To go there you have to go over the Atlas Mountain range, across the famous Tizi N'Tichka, and then point towards Aguelmouss, Ighrem N'Ougdal, Agouim and Ait-Ben-Haddou. But, just before reaching Aguelmouss, you can leave the main road (the N9) following the secondary one (the P1506) towards Télouet. Once there you can only go through the Ounila Valley and you'll see a wonderful red landscape that will stay forever in your mind. Don't miss the visit to the salt cave (approximately 31.292130, -7.184457), a gloomy but unforgettable place.
