Visit Anzali Lagoon to witness a fragile international wetland where quiet waters meet rich bird life along the Caspian shore.

The place

Anzali Lagoon sits as a remarkable coastal liman in the northern Iranian province of Gilan, right along the edge of the Caspian Sea near the port city of Bandar-e Anzali. The wetland environment physically splits the town into two distinct halves, creating a watery maze where land and sea blur together. Because of its specific geographical position, the area experiences high levels of humidity and rainfall that set it apart from most other wetlands across the country, though water levels fluctuate considerably depending on seasonal rains and dry spells. The wider ecosystem encompasses protected zones such as the Selke Wildlife Refuge and the Siahkesheem Marsh, providing crucial habitats for a great variety of wildlife.

Recognised internationally for its ecological importance, Anzali Lagoon earned protection under the Ramsar Convention. Yet this watery expanse faces serious environmental pressures. Urban waste and industrial runoff from nearby settlements have accumulated in the basin, threatening the survival of numerous animal species and dozens of resident and migratory birds. Local authorities and conservationists continue to grapple with how to balance regional development plans with the preservation of this delicate coastal habitat. Travellers arriving here find a landscape of quiet reed beds and floating vegetation, framed by the grey-blue expanse of the Caspian Sea and the damp, fertile air of the northern coastal plain.

Its story

The environmental history of Anzali Lagoon is one of continuous physical transformation, shaped by shifting sea levels, changing upstream irrigation practices, and human intervention over generations. Historical studies show that the lagoon possessed significantly higher water salinity during the nineteenth and early twentieth centuries than it does today. Over the decades following the nineteen-thirties, the overall surface area of the wetland shrank dramatically, contracting to a fraction of its former expanse due to siltation, land reclamation, and changing water flows from tributary streams.

More recently, environmental dynamics have shifted again. Rising water levels in the broader Caspian basin have increased the interchange of water between the sea and the lagoon, while upstream agricultural irrigation has altered the balance of salt transport in incoming freshwater streams. This tug-of-war between fresh river inputs and brackish sea surges creates a gradient of salinity, with fresh waters dominating near tributary mouths and brackish conditions prevailing closer to the main harbour opening.

Despite ongoing ecological challenges, the wetland remains a notable destination for naturalists and bird watchers who come to observe the seasonal movements of waterfowl. Formal recognition arrived on twenty-first December nineteen seventy-five, when the site was officially registered under the Ramsar Convention on Wetlands. This designation placed international attention on the lagoon's biological richness, underscoring its dual identity as a fragile natural sanctuary and a heavily impacted coastal waterway.

What to see

Culture

At Anzali Lagoon and across the surrounding province of Gilan, visitors encounter a deeply hospitable culture rooted in regional traditions and warm social customs. While international media often portrays Iran through a tense political lens, ordinary Iranians are famously welcoming, generous, and genuinely curious about travellers from other lands. Conversations over tea are common, and guests are treated with immense care and respect. Persian etiquette places a high value on politeness; locals use honorifics such as Aghaye for men and Khanoome for women, frequently employing plural verbs and pronouns to show deference. When greeting, people often raise a hand to shake or offer a warm hug, accompanied by the welcoming phrase Kheili Khosh Amadid. At the same time, society retains a degree of insularity, and outsiders should remain mindful of local sensitivities regarding photography and political discussions. If you are male, avoid initiating a handshake with a woman unless she offers her hand first.

What to wear

Around Anzali Lagoon and the humid northern province of Gilan, traditional clothing reflects both practicality and regional heritage. Historically, communities living near the Caspian Sea wore loose, lightweight garments suited to heavy rainfall and subtropical humidity, utilising local textiles and natural fibres. Today, urban residents in nearby Bandar-e Anzali dress in standard contemporary Iranian styles, with men wearing trousers and shirts, while women wear trousers or skirts paired with coats or tunics, accompanied by a headscarf. For visitors exploring the wetland, clothing should balance local modesty standards with comfort in a damp, humid climate. Lightweight, breathable fabrics such as cotton work best for warm days, while a waterproof layer is essential given the region's frequent rainfall. Women must observe national dress codes by wearing a headscarf, loose trousers, and a tunic or coat that covers the arms and hips. Men should wear full-length trousers rather than shorts. Sturdy walking shoes or sandals are recommended for navigating damp paths and boat docks around the lagoon.
