Nashtarud Lagoon

Nashtarud Lagoon is one of the most notable natural attractions of Mazandaran Province and one of the sights of Tonekabon County. It lies in the center of the town of Nashtarud, about 5 km from Tonekabon. This body of water, roughly 3 km long and nearly 50 m wide, sits within the urban fabric and is positioned so that many of the town's north–south routes end at it. Its unique setting next to the town and its bazaar makes it one of the most unusual blends of nature and city scenery in northern Iran.

Ecologically, Nashtarud Lagoon is an important habitat for various aquatic species and birds. It is a spawning ground for fish such as carp, Caspian roach (sefid), mullet and pike, and in the colder months it hosts migratory birds such as ducks and coots. The relative calm of the water, compared with the steep, fast-flowing rivers of the region, creates good conditions for recreation and nature tourism. The boats on the lagoon and the natural scenery around it give the place a distinctive, pleasant atmosphere and make it a popular spot for photography and relaxing.

Nashtarud Lagoon is very easy to reach: take the Tonekabon road toward Abbasabad to reach the town of Nashtarud, and the lagoon is there. The best time to visit is spring and early autumn, when nature is at its most beautiful and the weather is more suitable for sightseeing. When visiting this valuable ecosystem, it is especially important to follow the principles of responsible nature tourism, avoid harming wildlife and keep the environment clean, so that this natural and urban ecosystem is preserved for future generations.
