From Ouarzazate, the N9 plunges southeast into the Draa Valley, formed by a narrow ribbon of water from the High Atlas that occasionally emerges triumphantly in lush oases, particularly between Agdz and Zagora, a stretch of about 95km. The drive from Agdz to Zagora takes three to four hours, though the more scenic Circuits Touristiques route follows the piste through the oasis. Beyond that, a road takes you 96km further south to M’Hamid, a town 40km short of the Algerian border that marks the end of the road and the start of the desert proper.
Erfoud makes a pleasant pit stop on the journey heading south to Merzouga from Fez or Meknes, with wood-fired madfouna (Berber 'pizza'), fossils dating back hundreds of millions of years and the photogenic ancient Ksar M’Aadid, 5km north of town. The souq at the southern end of Erfoud sells local dates and fresh produce, and in October the town has an increasingly popular date festival, with dancing and music.
After crossing the rocky and forlorn expanses of the hamada (stony desert) south from Tarfaya, the Western Saharan city of Dakhla is an appealingly relaxed destination. A constant feature is the cobalt intensity of the Atlantic Ocean, softened here by palm trees, a pleasant oceanfront esplanade and a shallow island-studded lagoon.
The delightful resort town of Oualidia (also spelled Walidiya) spreads around a gorgeous crescent-shaped lagoon fringed with golden sands and protected from the wild surf by a rocky breakwater. With a good selection of accommodation and great fish restaurants (the town is particularly famous for its oysters), it's a popular weekend and summer retreat for Marrakshis and Casablancais, and a perfect destination for those needing a break after the bustle of the Marrakesh medina.
Oujda is the largest city in eastern Morocco, with a modern facade that belies its millennium-old age. Despite its heritage, it receives very few foreign travelers. The reason for this is found on the map: it was once the busiest border crossing with Algeria, making it popular with traders and tourists alike. When the border closed in 1995, Oujda's economy took a major hit. However, recent tourism development along the nearby Mediterranean coast, and the consequent rise in importance of the airport, are having a positive knock-on effect. In addition, Oujda's university remains a mainstay of the economy and the city’s intellectual life.
In its heyday, Fez attracted scholars and philosophers, mathematicians and lawyers, astronomers and theologians. Craftsmen built them houses and palaces, kings endowed mosques and medersas (religious schools), and merchants offered exotic wares from the silk roads and sub-Saharan trade routes. Although Fez lost its influence at the beginning of the 19th century, it remains a supremely self-confident city whose cultural and spiritual lineage beguiles visitors. Something of the medieval remains in the world’s largest car-free urban area: donkeys cart goods down the warren of alleyways, and while there are still ruinous pockets, government efforts to restore the city are showing results.
