Kolagh Laneh Peak

Kolagh Laneh Peak (known by this name in some Persian sources and also called Gharghalan in local sources) is one of the summits of the Alvand mountain range in Hamedan Province, with unique natural scenery and climbing opportunities. The peak lies south of the city of Hamedan and is part of the broad Alvand ridgeline. Its height is reported as about 3410 meters, roughly level with other parts of the range, and it stands out alongside Alvand Peak and the other surrounding summits.

On the lower slopes of the Alvand massif, the vegetation consists of rangeland plants and shrubs that tolerate drought and cold. With increasing altitude, it thins out to sparse mountain plants. This mountain ecosystem suits a variety of wind- and cold-resistant vegetation and fits the semi-arid mountain climate of this part of the Zagros. The wildlife of the area includes small mountain species and mountain birds, found in sheltered spots and folds in the terrain.

The route to Kolagh Laneh Peak usually starts from the Ganjnameh parking area in Hamedan. After you reach the Mishan Plain, the route continues toward Takht-e Nader and then traverses the "Dozakh Dareh" valley until it reaches the Kolagh Laneh hut. From the hut, a footpath continues toward the summit, and parts of it are rocky and require extra care. The Alvand massif also lets you climb Alvand Peak along the same route, and this combined route is popular with climbers. The best time to climb is from spring to early summer, when the weather is milder and conditions for trekking are better.
