Also known as: Laar National Park, Lar Mount, Damavand Mount

These mountains form the two branch ranges of the central Alborz Mountains, and are the highest sections of this range. To the north, after the Kahu (Sefid Ab) Pass, in the village of Garmabdar (district of Roodbar-e-Qasran), it sub-divides into two, the north western and south eastern ranges.

In the south western sector are the peaks of Takht-e-Khers and Seh Sang, extending towards the west, where the gigantic Damavand Peak is visible. In the south eastern sector, after running along the plains of Lar, the famous peaks of Haft Saran are apparent, and to the south of these plains are the peaks of Mehr Chal, Atashkadeh, Siyah Chal and Maaz. In the south eastern direction it joins the Khansak and Shad Kooh Mountains.
