A 1,600–1,900 km loop from Marrakech threads kasbah towns to the sands of Erg Chebbi and Erg Chigaga in late October, when days run 10–11 hours and desert highs sit near 24°C. Three 4x4s travel as a convoy, mixing paved valleys and classic pistes like Lac Iriki. The plan hinges on clear convoy rules, sand driving basics, and practical logistics in places like Ouarzazate, Tinghir, Rissani, Zagora, and M’Hamid. Fuel, cash, and water dictate pace; wind and flash-flooded wadis dictate route. The goal is simple: keep margins wide and connect Morocco’s fortified mud-brick towns to its open ergs safely.
