Kayes is the big city of Mali's far west, stretched along the banks of the Senegal River near the borders with Senegal and Mauritania. It has an unusual reputation: that of being one of the hottest cities in Africa, a Sahelian furnace where the thermometer easily tops 45 °C in the hot season. But beyond the heat, Kayes is a city with history: it was a key hub on the legendary Dakar-Niger railway and the first capital of French Sudan, before Bamako.
Its main appeal lies both in the city itself — with its railway and colonial heritage — and in its surroundings: a few kilometres away is the historic Médine fort, witness to the colonial wars and the epic of El Hadj Oumar Tall; and along the Senegal River lie the Félou falls and the even more spectacular Gouina falls, true 'Niagaras' of the Sahel. The region is also the heartland of the Soninke people and the main cradle of Malian emigration.
As with all of Mali, honesty is essential: the country is living through a very serious security crisis and foreign ministries advise against travel. The Kayes region and its roads have not been spared the violence. That is why this guide serves a mainly cultural and informative purpose, and any travel decision must rest on up-to-date official advisories and professional security advice.
Kayes was born and grew with the Senegal River and the railway. In 1855, the French governor of Senegal, Faidherbe, had the Médine fort built near present-day Kayes to control river navigation; two years later, in 1857, the fort withstood a long siege by the troops of El Hadj Oumar Tall, a religious leader fighting the French and the kingdom of Khasso. Kayes became a river port and the starting point of the Dakar-Niger railway, and it was the first capital of French Sudan (1892-1899) before the capital moved to Bamako. Its full story is told on our history page.

Origins, formation and what the sources say.
Western Mali, where Kayes stands today, is a land with deep history. It is the heartland of the Soninke people, heirs to the ancient Ghana Empire (Wagadou), which between the 4th and 11th centuries was the first great trading power of the western Sahel, controlling the gold and salt trade long before the Mali Empire. The Soninke left a lasting mark on the region, in its social organisation, its Islam and its long-distance trade networks.
In the centuries before colonisation, the upper Senegal River area was organised into kingdoms such as Khasso, home to the Khassonké, a people of mixed Fulani and Mandinka origin. The Senegal River, which rises in the highlands of Guinea and flows into the Atlantic, was the great route for communication and trade in the west, and controlling it was key for any power that wanted to dominate the region.
By the mid-19th century, two forces were competing for that control: on one side, the French, who were pushing inland up the river from their base in Senegal; on the other, the great Muslim religious movements, above all the jihad of El Hadj Oumar Tall. The clash between them would shape the history of Kayes and of all of western Mali.
The historical episode that put this region on the map was the building of the fort at Médine and the siege it endured. In 1855, Louis Faidherbe, the energetic French governor of Senegal and the chief architect of colonial expansion, ordered a fort built at Médine, on the Senegal River, near present-day Kayes. The aim was to control river traffic and strengthen the French push into the interior of West Africa, towards the Niger.
The building of the fort ran head-on into the jihad of El Hadj Oumar Tall, the Toucouleur religious leader of the Tijaniyya brotherhood who sought to build a Muslim empire and drive out the French. In 1857, El Hadj Oumar Tall's troops laid siege to the fort at Médine in a long and bitter siege, as part of his war against the kingdom of Khasso, an ally of France. The French garrison, backed by its African allies, held out until a relief column led by Faidherbe himself arrived and broke the siege.
The defence of Médine was a turning point in the colonial conquest of the upper Senegal and of what would become French Sudan. It consolidated the French presence in the region and opened the way to the Niger. The fort at Médine, still standing near Kayes, is today the great reminder of that clash of empires and of the epic of El Hadj Oumar Tall.
Once the conquest was secured, Kayes grew quickly thanks to its strategic position on the Senegal River, at the point up to which the river was navigable from the Atlantic during the high-water season. The town became a river port and the gateway for the colonial push towards the Niger. It was so important that Kayes was the first capital of French Sudan (today's Mali) from 1892 to 1899, before the capital moved and, finally, in 1908, went to Bamako.
The great driver of Kayes's growth was the railway. The building of the Dakar-Niger line, which linked the Atlantic port of Dakar (Senegal) with the Niger River at Koulikoro, crossing western Mali, made Kayes an essential railway hub, with a station, workshops and depots. The railway transformed the region's economy, carrying goods, troops and travellers, and tied Kayes for good to the history of the train in West Africa.
That double role, river port and railway town, gave Kayes a notable colonial and railway heritage that can still be traced in its station, its buildings and its street layout. The town established itself as the main urban centre of the west, although its extreme heat also made it famous as one of the hottest places on the continent.
After Mali's independence in 1960, Kayes and its region developed a trait that still defines them today: emigration. The Kayes region became the main source of the Malian diaspora, above all towards France, but also towards other African countries, Europe and the rest of the world. The Soninke in particular have a very long tradition of migration, linked to their culture of long-distance trade and reinforced by economic hardship and the droughts of the Sahel.
This mass emigration has deeply transformed the region. The money emigrants send home to their villages has paid for houses, mosques, schools, health centres, wells and other infrastructure, changing the look of many villages. The bond between the Kayes region and its diaspora is so strong that the area's social, economic and cultural life cannot be understood without it: emigrants keep close ties with their communities and take part in their development from afar.
This makes Kayes an unusual region, with one foot in the Sahel and the other abroad, shaped by comings and goings, remittances and projects funded from outside. It is one of the keys to understanding society in western Mali and its relationship with the world.
Today, Kayes is still the major city of western Mali, a commercial, administrative and service centre for a vast region. The Senegal River remains its lifeline, and its waterfalls, Félou and Gouina, have also become a source of energy: the Félou hydroelectric plant, completed in 2014, and the projects at Gouina harness the river's force to generate electricity, as part of regional cooperation across the Senegal basin.
The region has a rich heritage: the fort at Médine, the Senegal River waterfalls, the town's railway and colonial legacy, and the living culture of the Soninke and Khassonké peoples. In its day, all of this made Kayes an interesting destination for travellers looking for a different side of Mali, more closely tied to colonial history and the great river landscapes of the west.
However, like the rest of the country, Kayes lives under the shadow of the serious security crisis that has affected Mali since 2012 and that, especially since 2022, has also spread to the west, with incidents and attacks in the region and on its roads. Foreign ministries advise against travel to the country. This historic city on the Senegal River thus faces the challenge of preserving its heritage and its way of life in a very difficult national context, and any visit must be based on official security advice.
