Marrakech is close enough to the Sahara to make camel trekking in Morocco, on a 4 or 5 day tour from Marrakech, possible. Cross the Atlas Mountains and travel along oasis river valleys, through Berber villages and past abandoned kasbahs to the edge of the largest desert in the world. See the desert on an Erg Chebbi camel trek from Merzouga or an Erg Chigaga camel trek from a desert camp. Desert tours run from Marrakech to Marrakech or Marrakech to Fes via the Erg Chebbi dunes.
