Taking a 3-day desert tour to Erg Chebbi dunes in Merzouga means sitting in the car for ten hours on the day's last day from Merzouga to Marrakech. We, therefore, recommend a minimum of 4 days for a Desert Tour from Marrakech to Erg Chebbi to break the journey each way and have time to see the sites along the route. The 4 Days Sahara Desert Tour to Erg Chebbi dunes and back to Marrakech are highly recommended simply because there are so many things to see and do besides camel trekking and a night stay in a deep Sahara desert camp.
