Imamzadeh Ali Lake

Imamzadeh Ali Lake lies along the Haraz Road, near the village of Ab Esk. It is regarded as one of the most striking natural attractions in the Larijan district of Amol County, in Mazandaran Province. Today the lake is a popular destination for nature lovers. It formed after the large landslide of 1377 (Solar Hijri) along the Haraz River. The landslide blocked part of the riverbed and created a calm blue expanse in the heart of this mountainous region.

The lake is estimated to be about 700 metres long and 130 metres wide, and its appearance still bears traces of the former river. The lakebed is covered with branches, plants and the remains of the natural vegetation that existed before the landslide, and this combination creates a distinctive and unique landscape. The water is home to species such as brown trout (red-spotted trout) and rainbow trout, and it is still managed under the supervision of a local fishing club. Anglers can therefore enjoy a pleasant experience in a quiet mountain setting.

To reach the lake, take the route from Jajrud to Abali, then on to Polur and Ab Esk. From there, a short access road continues to the lake. Because of the region's climate and the mountain road, the best time to visit is from late spring to mid-autumn, when travel is easier and the scenery looks clear and vibrant. Practising responsible nature tourism plays an important part in sustaining this natural environment. This means not leaving litter, protecting the vegetation and behaving appropriately while fishing, all of which helps preserve its beauty for future generations.
