The triangular Sinai peninsula extends from the Mediterranean sea soutwards into the Rea Sea. It measures 400km from north to south and 200km east-west and is mostly desertic. The Sinai peninsula is relatively flat in the north and mountaineous in the south. The highest elevation is Mt St Catherine (2629m). Nearby lies the 2285m high Mount Sinai where supposedly Moses received the ten commandments from God. It attracts a large number of tourists who come to relax on its beautiful Red Sea coast and to visit the historic sights.
