Few journeys in the world are as raw, as photogenic and as legendary as Mauritania's iron ore train. Picture a steel serpent up to three kilometres long, with hundreds of wagons loaded with ore, crawling through the most absolute Sahara, between dunes and endless horizons, under a sky that turns from the blinding white of midday to the starry blanket of the desert night. Now picture yourself on top of one of those wagons, sitting on a mountain of iron, covered in black dust, living one of the most intense travel experiences on the planet.
This train is not a tourist attraction: it is the backbone of Mauritania's economy. Since 1963 it has carried iron ore from the mines of Zouérat, in the heart of the desert, to the port of Nouadhibou on the Atlantic, 704 km to the west, where it is shipped around the world. It is one of the longest and heaviest trains in existence, run by the state company SNIM, and its daily crossing of the empty Sahara has become a rite of passage for adventure travellers who make it to Mauritania.
This guide tells you everything you need to know to do it: how the train works, which stretches to ride (the classic Choum-Nouadhibou), the two ways to travel (on the ore, free and out in the open, or in the humble passenger car), how to prepare for the cold, the heat and the dust, and what precautions to take. Riding the iron ore train is hard, uncomfortable and dirty, and that is exactly why it's an adventure you will never forget.
The iron ore train was born with the mining that made Mauritania modern. In the mid-20th century, huge reserves of high-grade iron ore were found in the Kediet Ijill mountains, near what would become Zouérat, deep in the Sahara. To export it, it had to reach the sea, so the company MIFERMA built, around 1963, a railway of some 700 km across the desert to the port of Nouadhibou, even going around the territory of Western Sahara through a tunnel. After mining was nationalised in 1974-1975, the train passed to the state company SNIM, which has run it ever since. Its story, that of the iron that keeps the country going and of Africa's most astonishing railway, is told on our history page.

Origins, formation and what the sources say.
The story of the iron ore train begins with a mountain. In the far north of Mauritania, deep in the Sahara, rises the Kediet Ijill massif (or Kediet ej Jill), the highest point in the country. This dark mass turned out to hold one of the largest and purest concentrations of iron ore, known as haematite, anywhere in Africa. People had long known there was iron in the area, but it was in the first half of the 20th century that geological surveys revealed how enormous the deposit was. Here, in the middle of the harshest desert, lay enough wealth to transform an entire country's economy.
The problem was obvious. The ore lay more than 600 km from the sea, in a desert with no roads, no water and hardly any people, one of the most remote and inhospitable places on the planet. Mining the iron was pointless unless it could be carried out to a port and shipped to the steelworks of Europe. The only workable answer was to build a railway right across the Sahara, from the mines to the Atlantic coast. It was a colossal and risky undertaking, on a par with the great industrial epics of the century.
In 1952 the company MIFERMA (Société des Mines de Fer de Mauritanie) was set up to work the deposit, with French, British, Italian and other European capital. The plan called for mines at Zouérat, a deep-water port at Nouadhibou (then Port-Étienne) and a railway across the desert to link them. All this coincided with Mauritania's birth as an independent country in 1960, so from the very start the iron ore train was a central piece in building the new state.
Completed around 1963, the railway was a feat of engineering. More than 650 km of track had to be laid across extremely tough terrain: shifting dunes that threatened to bury the rails, stony plains, extreme temperatures and a complete lack of infrastructure, water and local labour. Materials and workers were brought in, the sand was fought day after day, and the result was a line strong enough to carry giant trains loaded with something as heavy as iron.
One of the most curious episodes had to do with geopolitics. The most logical route to Nouadhibou skirted the territory of what was then the Spanish Sahara (today Western Sahara). To avoid crossing land under someone else's control, the engineers dug a tunnel, the so-called Choum tunnel, which kept the line on Mauritanian soil. Years later, after political changes in the region, the trains switched to the shorter outer route, which does cross a stretch of Western Sahara. The tunnel remains as a reminder of the border tensions of the time.
The result was a line of about 704 km linking Zouérat with Nouadhibou, crossing the desert and passing through the Choum junction. From 1963 trains began running along it, loading ore at the northern mines and carrying it to the Atlantic port for export. One of the most extraordinary railways in the world had been born, a steel artery driven into the heart of the Sahara.
In its early years the mine and the railway belonged to MIFERMA, the foreign-owned company. But in the 1970s, amid the economic nationalism sweeping the post-colonial world, Mauritania decided to take back control of its main source of wealth. In 1974 the government of President Moktar Ould Daddah nationalised MIFERMA, and in 1974-1975 the state company SNIM (Société Nationale Industrielle et Minière) was created. Ever since, it has run the whole complex: the Zouérat mines, the railway and the ore port at Nouadhibou.
SNIM became the largest company in the country and one of the pillars of its economy. For decades iron ore has been one of Mauritania's main exports, often the biggest, and its sale to steelworks in China, Europe and other markets provides a crucial share of state revenue. New mines joined Kediet Ijill, such as Guelb El Rhein (discovered in 1981) and Mhaoudat, raising output to several million tonnes a year. All of that ore travels, without exception, on the iron ore train.
So the railway is neither a relic nor a tourist novelty. It is the living backbone of the Mauritanian economy and has run every day for more than sixty years. Every train that crosses the desert carries the livelihood of thousands of families, the state's income and a large part of the country's GDP. Understanding this means understanding why the train never stops, and why the journey carries a weight that goes far beyond adventure.
Over time, Mauritania's iron ore train earned a place both in travellers' imaginations and in the railway record books. To move the huge volume of ore efficiently, SNIM runs enormous trains of 200 to 300 wagons. They stretch for two to three kilometres, weigh tens of thousands of tonnes in total and are hauled by several diesel locomotives. It is often listed among the longest and heaviest trains in regular service anywhere, and watching it cross the desert, with kilometres of wagons rippling along the horizon, is hypnotic.
Very early on, the train started carrying people as well as ore. For the people of the desert (nomads, traders, workers), it was for decades practically the only way to travel between the interior and the coast. Riding for free on top of the ore wagons, or in the basic passenger car coupled to the train, became part of daily life in the Mauritanian Sahara. That custom, born of necessity, is what lets adventure travellers join the journey today.
Over the years, the ride on top of the ore, exposed to the sun, the night-time cold and the ever-present black haematite dust, became a travel legend. It is one of those bucket-list experiences that draws backpackers and photographers from all over the world to this corner of the Sahara. Documentaries, features and travel stories spread the image of the giant train and the adventurers perched on its wagons, until the iron ore train became one of Mauritania's great tourist icons.
Today, more than sixty years after its first run, the iron ore train still plays a double role. It is the economic artery that keeps Mauritania alive and, at the same time, one of the most sought-after travel adventures on the planet. Every day, kilometre-long trains cross the desert between Zouérat and Nouadhibou loaded with haematite. On top of them, or in the passenger car, ride both Mauritanians who use it to get around and foreign travellers looking for an extreme experience.
The journey is as raw as it ever was. There are no comforts, no services and no reliable timetables. There is sun, cold, wind, dust, discomfort and overwhelming beauty. That is exactly why it has become a rite of passage, a way of travelling 'for real' that stands in contrast to comfortable tourism. Crossing the Sahara sitting on a mountain of iron, covered in black dust, under the clearest starry sky in the world, is one of those experiences that stays with you.
The train's future is tied to that of Mauritanian iron and to the plans of SNIM, which is updating its rolling stock and studying expansions. As long as ore keeps flowing from the heart of the Sahara to the sea, the iron ore train will keep rolling. For Mauritania it is much more than a railway. It is the symbol of the country's wealth and the industrial achievement that put it on the map. For travellers, it is the gateway to an unforgettable adventure in one of the most impressive deserts on Earth. Few things capture the soul of this country better than that endless steel serpent crossing the golden emptiness of the Sahara.
