Div Asiab Spring Lake

Div Asiab Spring Lake lies in the northern highlands of Lar Plain, on the border between Tehran and Mazandaran provinces, on the southern slopes of Mount Damavand. This small, circular lake, about 20 meters in diameter and 2 meters deep, is hidden inside a limestone hill 10 meters high. Its water wells up from two underground vents and flows into the Sefidab River. Because of its sulfur minerals, the color of the spring water varies through the seasons from light blue to gray, and it has a sour taste. These features have made the Div Asiab Spring one of Iran's most unique natural attractions.

The water of Div Asiab Spring is of the sulfurous bicarbonate type and has therapeutic properties thanks to its mineral content. It is said to help strengthen the muscles and is known as a natural remedy for certain ailments. The water bubbling up from the spring's two vents creates a beautiful, captivating scene that draws the attention of every visitor. The lake lies between the Delichay and Sefidab rivers and is known as one of the most popular nature-tourism destinations in northern Iran. The vegetation around Div Asiab Spring includes medicinal and alpine plants such as poppies, borage, thyme, pennyroyal, wild garlic (musir), valak and astragalus (goon). Together with the wide meadows and the slopes of Mount Damavand, these plants create beautiful scenery. Besides its beauty, this vegetation reflects the biodiversity and ecological importance of the region.

To reach Div Asiab Spring Lake, take the Haraz Road toward Polur and then head toward Lar Dam. After passing the ranger station, you will reach the Aru nomads' settlement, which is the starting point of the hike to the lake. This mountain trail takes about 3 to 4 hours and requires good physical fitness and suitable equipment. The best time to visit the lake is spring, when Lar Plain is covered with poppies and the weather is pleasant. In summer, you can also enjoy the spring's cold water and camp beside it. To preserve the area's natural beauty, please avoid harming the environment, and collect your trash and take it to designated areas.
