The North of the province is a humid to semi-humid mountainous region, while the south is dry.
Taleghan is the coldest town and Eshtehard is the hottest town of the province. Summer is the best time for visiting this area as it has mild weather then. However, Ski resorts in the north of the province host man tourists during the winter period.
