Liwa Oasis is about 100 km south of the Persian Gulf coast and 150 km SSW of the city of Abu Dhabi, on the northern edge of Rub' al Khali desert.It is centered around 23°08′N 53°46′E and stretches about 100 km east-west, along an arch curved to the north. It consists of some 50 villages. The geographic and economic center of the oasis is Muzayri`, where the highway from Abu Dhabi enters the oasis and then divides to the east (65 km to the easternmost village, Mahdar Bin `Usayyan) and west (45 km to the westernmost village, `Aradah).
There are no statistical data available, but judging from satellite images, the population is estimated at 50,000 to 150,000.The villages of Liwa Oasis are the southernmost settlements of Abu Dhabi and of the United Arab Emirates. The southern border of Abu Dhabi with Saudi Arabia, which runs at a distance between 16 and 35 km to the Oasis, is a straight line in the Rub al Khali desert, which is largely uninhabited. Mahdar Bin `Usayyan is the southermost village of the Emirates, and also the easternmost of the oasis.10 km south of the border, and 40 km south of the eastern part of the oasis is the Saudi oil town Shaybah. However, there is no road linking Liwa Oasis and Shaybah, and no border crossing.A modern, multilane highway connects the oasis area to the capital, Abu Dhabi.
