the Empty Quarter
Located in the Wilayat of A’Sunaynah, Ramlat Duhayth is a part of the Rub Al Khali (the Empty Quarter) known for some of the largest mega sand dunes in the world. Exploring the area is only possible by 4WD vehicle. It is recommended to go as part of a group with more several cars just in case one gets stuck in the sand.
Rubʿ al-Khali, (literally “Empty Quarter” in Arabic), also spelled Al-Rabʿ al-Khali, is a vast desert in the southern Arabian Peninsula, covering about 250,000 square miles (650,000 square km) in a structural basin that takes in a substantial portions of Saudi Arabia, as well as parts of Oman, Yemen, and the United Arab Emirates. It is the largest area of continuous sand in the world. It holds roughly half as much sand as the Sahara, which is 15 times the Empty Quarter’s size but composed mostly of graveled plains and rocky outcrops.
The desert is 1,000 kilometres long, and about 500 kilometres, and its topography is varied. In the west the elevation is as high as 2,000 feet (610 metres) and the sand is fine and soft, while in the east the elevation drops to 600 feet (183 metres) with sand dunes, salt flats, and sand sheets. The terrain is covered with sand dunes with heights up to 250 metres (820 ft), interspersed with gravel and gypsum plains.
