Alam Kuh (also Alam Kooh, Persian: علم کوه) is a mountain in the Alborz mountain range in the north of Iran between Tehran and the Caspian sea, forming a peak of the Takht-e Suleyman Massif. At 4,850 m high, it is the second highest peak in Iran, only to Mount Damavand at 5,671 m.
The 800 m high steep granite north face provides some of the most difficult and interesting mountaineering routes in the country and the climbs rank alongside major climbing routes in the European Alps. In addition to local climbers, the north face attracts European climbing teams, the first known ascent being by a German party Gorter/Steinauer in 1936 up the north west ridge.
The mountain range supports permanent snow and glaciers and although the southern slopes of the range tend to be dry and barren the northern valleys leading to the Caspian Sea (which offer the best approaches to the mountains) are wet and lush with vegetation.
