The Zagros Mountains (Kurish: Zagros - زاگرۆس, Persian: رشته كوههاى زاگرس), make up Iran's and Iraq's largest mountain range. They have a total length of 1 500 km from western Iran, on the border with Iraq to the southern parts of the Persian Gulf. The mountain range ends at the Straits of Hormuz. The highest points in the Zagros Mountains are Zard Kuh (4 548 m) and Mt. Dena (4 359 m). The Hazaran massif in the Kerman province forms an eastern outlier of the range, the Jebal Barez reaching into Sistan.
