Kelardasht (Persian: كلاردشت, also Romanized as Kalārdasht) is a city in and the capital of Kelardasht District, in Chalus County, Mazandaran Province, Iran. At the 2006 census, its population was 11,921, in 3,361 families.
The city is composed of 5 districts (Hasankif, Lahoo, Kordichal, Valbal and Mejel). Hasankif has been the business district for many years and is currently also the political center.
Originally a farming area, in recent years much of its land was sold in small lots to build numerous villas which are occupied by summer visitors trying to escape the heat of Tehran and points further south.
Its attractions mainly consist of its natural beauty, including Alamkooh Mountain (the second tallest peak in Iran (4850 m)), Abbasabad Road, Valasht lake and cooler climate. But picnicking and mountain climbing in the area surrounding Rud-Barak are also popular, as well as in the lush Abbasabad Forest nearby.
The majority of the inhabitants speak Gilaki, but a few migrants speak Kurdish.
