Natural features divide the country into six distinct areas: Ru'us al-Jibal, including the northern Musandam Peninsula; the Batinah plain running southeast along the Gulf of Oman coast; the Oman interior behind the Batinah coast comprising the Hajar Mountains, their foothills, and desert fringes; the coast from Muscat-Matrah around the point of Ras Al Hadd, and down the Arabian Sea; the offshore island of Masirah; and finally the barren coastline south to the Dhofar region in the south.
