The Western Desert in Egypt extends east-west from the west bank of the Nile until the border to Lybia for 600km and for almost 1000km from north to south. Several oases are located in the western desert, of which the largest and most important ones are the Kharga, Dakhla, Farafra, Bahariya and Siwa oases. Only parts of the western desert are accessible to tourists. Near the oasis of Farafra lies the White Desert, named after the white rock formations located in it. Siwa is a very large oasis surrounded by sand desert near the border to Lybia.
