Rather than retracing the N10 back to Marrakesh via Tinerhir and Ouarzazate, adventurous desert travellers opt for the N12, which traces the southern foothills of Jebel Saghro via Alnif, Tazzarine and Nkob. The road sees little traffic and few tourists and provides an interesting link through prime fossil-hunting territory to the Draa Valley, where it emerges at Tansikht 63km north of Zagora and 98km south of Ouarzazate. Kasbah-studded Nkob is the most atmospheric place to stay and provides a good base for Jebel Saghro treks and exploration.
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.
Nomad crossings, rose valleys and two-tone kasbahs: even on paper, the Dadès Valley stretches the imagination. From the daunting High Atlas to the north to the rugged Jebel Saghro range south, the valley is dotted with oases and mudbrick palaces that give the region its fairy-tale nickname – Valley of a Thousand Kasbahs. Some of the best views are only glimpsed when travelling on foot, along hidden livestock tracks between the Dadès and Todra Gorges and nomad routes across the Saghro.
Al Hoceima is a great place to spend a few days. Quiet, relaxing and hassle-free, this modern seaside resort was founded by the Spanish as Villa Sanjuro. The town was built as a garrison after the Rif Wars in the early 20th century; rebel Abd Al Krim operated nearby. Independence brought the name change to Al Hoceima, but Spanish influence remains strong in language, architecture and business.
Being stuck between a rock and a hard place is a sublime experience in the Todra Gorge, where a 300m-deep fault splits the orange limestone into a deep ravine at some points just wide enough for a crystal-clear river and single-file trekkers to squeeze through. The road from Tinerhir passes green palmeraies (palm groves) and Berber villages until, 15km along, high walls of pink and grey rock close in around the road. The approach is thrilling, as though the doors of heaven were about to close before you.
Prepare for your senses to be slapped - Marrakesh's heady sights and sounds will dazzle, frazzle and enchant. Put on your babouches (leather slippers) and dive right in.
Midelt sits in apple country between the Middle and the High Atlas and makes a handy break between Fez and the desert. Coming from the north, in particular, the landscape offers some breathtaking views, especially of the eastern High Atlas, which seem to rise out of nowhere.
For pure mountain air that cuts through the heat and leaves you giddy, don’t miss the highest mountain in North Africa: snowcapped Jebel Toubkal (4167m), situated in the heart of the Toubkal National Park. Mountain trails criss-crossing Jebel Toubkal start from Imlil, which is located at the end of the Mizane Valley. On the way to Imlil, you could make a pit stop 47km south of Marrakesh at Asni for roadside tajines and the Saturday souq.
Snaking down through the dramatic Ziz Gorges from Rich, the Oued (River) Ziz brings to life the last southern valley of the Ziz and the Tafilalt oases before puttering out in the rose gold dunes of Merzouga. Starting just south of the Middle Atlas town of Rich and about 30km north of Errachidia, the tremendous Ziz Gorges provide a rocky passage south through the Tunnel du Légionnaire (built by the French in 1928). To the south, the valley widens, presenting a spectacular sight: a dense canopy of palms wedged between ancient striated cliffs, which date to the Jurassic period. It's worth taking some time here to explore the rich, untouristed palmeraies (palm groves).
When a wealthy family refused hospitality to a poor woman and her son, God was offended and buried them under the mounds of sand called Erg Chebbi. So goes the legend of the dunes rising majestically above the twin villages of Merzouga and Hassi Labied, which for many travelers fulfil Morocco's promise as a dream desert destination.
