The Rubh Al Khali. Part of the larger Arabian Desert, the Rubh Al Khali or Empty Quarter is the largest contiguous sand desert in the world, covering some 650,000 square kilometres across parts of Saudi Arabia, Oman, the UAE, and Yemen. The stunning Liwa Oasis is at the heart of it all and many say is the site that provides the ultimate desert camping experience. For a first-timer venturing into the desert it is advisable to have at least a couple of cars and an experienced guide for company.
