Great Dune information
Douz is the most convenient place to get a taste for the Sahara, though it's really only a taste. The Sahara desert proper starts 50km south of the Zone Touristique. Unless you're planning a longer excursion into the desert, the action centres around the great dune. It can't compare to the sand seas of the Grand Erg Oriental, but is a gentle introduction for those with limited time.
