The Moroccan village or ksar known as Tamegroute (also spelled Tamgrout) may be difficult to reach yet it is well worth the journey. This fortified mudbrick labyrinth on the edge of the Moroccan Sahara was for centuries an important center for religion and education. Walk passageways, both above and underground. Visit the Zaouia Naciri, built by the Naciri Sufi brotherhood and home to a marabout or holy tomb, religious institute for boys, and Koranic library. Tour medieval potteries. And if you are here to marvel at the Sahara, travel 5 km to the sand dunes at Tinfou or trek the last stretch of road 78 km to M'hamid.
