You are in for a nice surprise. An incredible trek in one of the least explored deserts of Iran. Its remoteness has meant that it has stayed pristine and four wheel drivers have not yet got to it. Few, if any people have walked the entire L shaped dunes separated by playas and beautiful dried salt lakes. It is some 50 aerial kilometres and probably over 70 ground kilometres. The altitude of the dunes is between 800 to 1100 meters above sea level. The best time to do it would be from mid October until late March. It is now on offer.
