Arabian Peninsula
Mountains

There are mountains at the eastern, southern and northwestern borders of the peninsula. Broadly, the ranges can be grouped as follows:

From the Hejaz southwards, the mountains show a steady increase in altitude westward as they get nearer to Yemen, and the highest peaks and ranges are all located in Yemen. The highest, Jabal An-Nabi Shu'ayb or Jabal Hadhur of the Haraz subrange of the Sarawat range, is 3,666 metres (12,028 ft) high. By comparison, the Tuwayr, Shammar and Dhofar generally do not exceed 1,000 m (3,300 ft) in height.

Not all mountains in the peninsula are visibly within ranges. Jebel Hafeet in particular, on the border of the UAE and Oman, measuring between 1,100 and 1,300 m (3,600 and 4,300 ft), is not within the Hajar range, but may be considered an outlier of that range.
