'There and deserts and there are deserts', the explorer Ralph Bagnold famously said. But the Western Desert, a vast expanse that starts at the western banks of the Nile and continues well into Libya, is the desert of deserts. Covering a total of 2.8 million sq km and bordered by Libya in the west, Sudan in the south and the Mediterranean in the north, it is a world of desolation and beauty -- and one of the few places in Egypt where you can go for days at a time without seeing a soul. Five isolated but thriving oases dot this otherwise uninhabited expanse: Kharga, Dakhla, Farafra, Bahariyya, and to the north-west of these, Siwa. (--from Lonely Planet, Egypt).
