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 east and then ascend Sarak Chal mountain (4210m).
