Negev Desert; This desert region in the southern part of the country comprises about half of Israel's land area but is sparsely populated. The region is bordered by the town of Beersheba in the North all the way to Eilat in the South. The topography parallels that of the rest of the country with lowlands in the West, mountainous region in the center, and a valley in the East. The southeastern region of the desert is the most arid with less than 50 milimeters of rainfall annually. At the southern tip of the Negev are the Eilat Mountains with colorful layers of sandstone.
