Mount Kolon Bastak in Northern Tehran

Northern Tehran has countless mountains above 4000 m, which are geographically located in the central Alborz mountains.  Mount Kolon Bastak is one of the highest summits in the Central Alborz region in Iran, with an altitude of 4170 m above sea level.  The closest village to this summit is Shemshak, 40 km north of Tehran and 60 km from central Tehran.  It is the most convenient place to choose for spending the night before your climb. Shemshak village has a 2700 m altitude above sea level.  It is famous for being one of the first ski resorts in Iran which opened in 1958.  It is the third largest ski area after Dizin and Darbandsar.

Mt. Kolon Bastak is an excellent choice for acclimatization before ascending Mt Damavand (5610m) and Alamkuh (4850m), as it is near Tehran city and is not a technical peak. No particular gear or special equipment is needed to ascend the peak in mid-spring, summer, and autumn. You can drive up to 3400 m to the base of the mountain, the starting point of the trek. From the peak, you can continue the trek through the ridge towards the east and then ascend Sarakchal mountain (4210m).
