Ait-Ben-Haddou is a cluster of earthen houses and towers on a hill above a river, on the caravan route between the Sahara and Marrakech, and on the UNESCO list since 1987. The road from Marrakech crosses the Tizi n'Tichka pass at about 2,260 metres, then Ouarzazate, and takes about four hours each way, so we plan it as a long day or as a stage on the way to the desert.
