Cloud Forest is one of the oldest and most beautiful forests in Iran. It is the continuum of northern forests in south of Alborz mountain range. It is located 50 Km north east of Shahrood. The forest is full of steep hills, and a river runs in there. Summer is the best time to see the forest, and the morning is the best time to take photos. When the clouds come, it will be very difficult to use a digital camera.
