Grand-Lahou is one of the most unusual and moving places on the Ivorian coast: a lagoon town where the great Bandama River, after crossing half the country, meets the Atlantic Ocean. It is called 'the town of three waters', because the river, the lagoon and the sea come together here in a landscape of water, sand and coconut palms. Home to the Avikam people, it lives from fishing and from a close, and at times dramatic, relationship with the water.
Its history has a unique chapter: old Grand-Lahou, or Lahou-Kpanda, a colonial settlement built on a narrow sand spit at the river mouth, which the sea and the shifting river mouth have gradually swallowed. Houses, churches and entire buildings have been engulfed by the water, in a slow shipwreck that turned the place into a worldwide symbol of coastal erosion and climate change. Walking through its ruins facing the ocean is an unforgettable experience.
This practical guide covers Grand-Lahou: how to get there from Abidjan, how to visit the old settlement and the river mouth by pirogue, what to see in Azagny National Park with its mangroves and wildlife, where to stay and eat, and how to get around this world of water. A destination for curious travellers and lovers of nature and powerful stories, looking for an authentic Côte d'Ivoire off the usual circuits.
In the early 20th century, Grand-Lahou was an important colonial comptoir and one of the first economic centres of the Ivorian coast, home to the Avikam people at the mouth of the Bandama. The old settlement, Lahou-Kpanda, flourished on a sand spit between the river, the lagoon and the sea, but coastal erosion and the shifting river mouth —made worse by the construction of the Kossou dam in the 1970s— gradually swallowed it, forcing the town to move inland in 1973. That story, from thriving comptoir to a town engulfed by the water, is told on our history page.

Origins, formation and what the sources say.
The land around Grand-Lahou has long been home to the Avikam people (also called the Brignan), a lagoon community of fishers and traders settled at the mouth of the Bandama River, where the river, the Tagba Lagoon and the Atlantic Ocean meet. This rare meeting of three waters (fresh, brackish and salt) shaped the community's life, economy and identity.
The Avikam lived from fishing in the lagoon and the sea, from gathering and from trade, making the most of their strategic position on the coast. Like other lagoon peoples of Côte d'Ivoire, they were in contact with the European sailors who travelled the Gulf of Guinea from the 15th century onwards, trading local goods for merchandise brought from Europe. The lagoon was at once a larder, a road and a border.
The mouth of the Bandama, one of the country's largest rivers, made this spot a link between the interior, whose goods and people came down the river, and the coast. That role as a meeting and trading point, along with the rich fishing in its waters, made Grand-Lahou an important settlement long before formal colonisation. It also laid the foundations for its later role as one of the first comptoirs on the Ivorian coast.
With French colonisation, made formal when the colony of Côte d'Ivoire was created in 1893, Grand-Lahou became an important comptoir (trading post) and one of the first economic centres on the coast. In the early 20th century the old town, known today as Lahou-Kpanda, flourished on the narrow sand spit at the river mouth, between the river, the lagoon and the sea.
French companies built trading houses there, along with administrative buildings, churches, colonial homes and everything else a busy port needed. Goods from the interior that came down the Bandama left through Grand-Lahou: palm oil, rubber, timber, and later coffee and cocoa. Imported goods came in the same way. The town went through a period of prosperity and became one of the busiest trading points on the Ivorian coast at the time.
As elsewhere on the coast, though, the rise of Abidjan drew trade away from the old coastal comptoirs, especially after the Vridi Canal opened in 1950 and gave the city its large deep-water port. Grand-Lahou began to lose its economic role, although it kept its fishing population and its beautiful setting between the three waters. The final blow, however, would come not from the economy but from nature itself.
The setting that had made Grand-Lahou's fortune, a narrow sand spit between the river, the lagoon and the ocean, also turned out to be its downfall. The mouth of the Bandama naturally shifts from east to west, and the coast suffers from strong marine erosion. Over the decades the sea and the river ate away the ground the old town stood on, at a rate of several metres a year.
Human activity made things worse. In the 1970s the large Kossou Dam was built upstream on the Bandama. It changed the river's flow and, above all, held back the sediment the river used to carry to the coast, which had helped replenish the sand on the spit. Without that supply, erosion sped up. Buildings, trading houses, churches and entire cemeteries of old Grand-Lahou ended up underwater or collapsed onto the beach.
As the water kept advancing, in 1973 the decision was taken to move the town inland to the site of present-day Grand-Lahou, some distance from the coast. The old town of Lahou-Kpanda was left half-abandoned, with a small community of fishers holding on among the ruins. It became one of the world's best-known symbols of coastal erosion and of what climate change does to coastal communities.
The Grand-Lahou area is more than a scene of erosion. It is also a natural treasure. Nearby lies Azagny National Park, a protected area of mangroves, wet savannah, swamps and forest along the lagoon and the Bandama. It was created to conserve one of the richest wetland ecosystems on the Ivorian coast.
Azagny is home to remarkable wildlife, including forest elephants, buffalo, monkeys, crocodiles, manatees and many waterbirds, and it is recognised as a wetland of international importance. An old colonial-era canal (the Asagny Canal) runs through the area, a reminder of efforts to link the lagoons by waterway. Today the park is an ecotourism destination and a reminder of the biodiversity found in the coast's lagoons and mangroves.
The park is managed by the Office Ivoirien des Parcs et Réserves (OIPR), and it gives Grand-Lahou another role: a gateway to a world of water and nature. Together with the drama of erosion and the beauty of the three waters, Azagny rounds out the picture of a region where the relationship between people and water is at the centre of everything. Sometimes that water gives life, and sometimes it is a threat.
Today Grand-Lahou lives between memory and hope. The new town, inland, is home to most of the Avikam population, who still make their living from fishing and from the lagoon, the river and the sea. The old town of Lahou-Kpanda, on the sand spit, has become a deeply moving place to visit. Its ruins facing the ocean tell the story of a town swallowed by the water and have become a powerful symbol of climate change and of how vulnerable coastlines are.
In recent years major coastal stabilisation works have begun, partly through West African coastal management programmes (such as the WACA programme, backed by the World Bank). They aim to slow erosion, strengthen the sand barrier and stabilise the mouth of the Bandama. These works offer hope to communities that for decades watched the sea carry away their land and their history.
For travellers, Grand-Lahou is a unique destination. Nature shows both its beauty and its power here. You can sail between three waters, visit the ruins of a town swallowed by the sea, explore the mangroves of Azagny and share the daily life of a fishing community. This is Côte d'Ivoire at its most authentic and moving, a country lived facing the water, remembering what was lost and determined to hold on.
