The Hajar Mountains are the highest mountain range within the eastern Arabian Peninsula. They located in northeastern Oman and the eastern United Arab Emirates. Lying 50 to 100 kilometers inland from the Gulf of Oman coast, they divide the low coastal plain of Oman from the high desert plateau.
The Hajar mountains start in the north, creating the Musandam peninsula. From there, the Northern Hajjar runs southeast, parallel to the coast but also moving gradually farther away as it goes. The middle section of the Hajjar is the Jebel Akhdar, which is the highest and wildest terrain in the country. Jebel Akhdar, in addition to the smaller Jebel Nakhl range, is bordered on the east side by the low Samail Valley. Eastwards of Samail are the Eastern Hajjar, which run east, towards the fishing town of Sur, nearly at the eastern point of Oman. Totally, the mountains stretch for 500 kilometers.
The low and coastal land that is north and east of the Jebel Hajjar is called Al Batinah Region, and the terrain that is inland of the mountains is Ad Dhahirah.
