The Al Hajar Mountains range in Oman, which stretches between 50 to 100 kilometers inland from the Gulf of Oman coast, includes Jebel Akhdar, sometimes known as "the Green Mountain," and stretches over 300 kilometers from northwest to southeast. One of Oman's most beautiful regions is this one. Jabal Shams (Mountain of the Sun), the highest point, is around 3,000 meters (9,800 ft) high. It is also the highest point in all of eastern Arabia and Oman. It is about 150 kilometers from Muscat and makes up the middle of the Al Hajar Mountain range.
