704 KILOMETRES OF TRACK
3 km TRAIN LENGTH (LOADED)
17,000t IRON ORE PER JOURNEY
~20 hrs TYPICAL JOURNEY TIME
1963 YEAR OF FIRST RUN
Somewhere between Nouadhibou and the iron-ore mines of Zouérat, a three-kilometre snake of metal grinds across the Sahara. It carries no seats, no toilets, no shade, and no apology.
Every few months, someone with a backpack, a set of ski goggles, and a surplus of optimism decides to climb aboard anyway.
The Mauritanian Iron Ore Train – officially the Train du Désert, unofficially “the Snake of the Desert” – has been crawling across one of the planet’s most forbidding landscapes since 1963.
Its job is straightforward: haul mineral wealth from the landlocked mines near Zouérat to the Atlantic port at Nouadhibou, 704 kilometres away, where the ore is loaded onto ships and exported to steel mills around the world.
It does this every day, rain or no rain (there rarely is), sandstorm or no sandstorm (there frequently is).
What its operators at the state mining agency SNIM did not plan for was the steady trickle of adventure-seekers who would one day treat it as the world’s most masochistic tourist attraction.
The Machine: A Monument of Industrial Scale
The numbers alone are staggering. According to Wikipedia’s documentation of the Mauritania Railway, the train consists of 200 to 210 ore wagons pulled by two diesel-electric EMD locomotives, stretching up to three kilometres from engine to last car – comfortably among the longest trains on Earth. Fully loaded, the entire consist weighs in the region of 17,000 tonnes.
The railway was built shortly after Mauritania’s independence from France in 1960 and inaugurated in 1963, designed as a pillar of the young nation’s economy.
Iron ore exports still represent one of Mauritania’s most significant sources of revenue, and the train runs 365 days a year to keep that revenue flowing.
The route cuts through northwestern Mauritania before threading briefly through a disputed sliver of Western Sahara – a quirk of post-colonial geography that once made this stretch a target for Polisario Front attacks in the late 1970s, effectively crippling the Mauritanian economy for years.
Today, that same section is a minor bureaucratic inconvenience: passengers must surrender their passports at Nouadhibou station to confirm they won’t slip across the border undetected.
“From the top of the iron ore, being able to overlook the vastness of the Sahara beyond the horizon, while greeting the occasional Bedouin and witnessing a breathtaking sunset, was an unbeatable experience.”
– Joan Torres, Against the Compass Travel Blog
The Passengers
Who Actually Rides This Thing?
The train was never built for passengers. There is, technically, a passenger carriage – an occasional addition managed by SNIM’s transport subsidiary ATTM – but its availability is erratic at best. Most people who board the train do not use it.
For many Mauritanians, particularly merchants, nomads, and people living in remote settlements along the line, the train is simply the most practical way to travel between the coast and the interior – a journey that by road requires a detour through the capital, Nouakchott, adding some 500 kilometres to the trip. They ride in the ore wagons freely, just as they have for decades.
One traveller described the scene from his perch atop the ore: a Mauritanian loading dozens of goats into a wagon fifteen cars back, and another man stacking what appeared to be his entire household contents into the wagon behind him.
Into this entirely functional, entirely non-touristic operation, the adventurous traveller has inserted herself.
No invitation was extended. No infrastructure was built for her comfort. She turns up at the station, wraps a turban around her face, pulls ski goggles over her eyes, and waits. This is the reality.
What the Experience Actually Involves
Accounts from travellers who have made the journey paint a consistent picture – one that is both genuinely spectacular and genuinely punishing, sometimes within the same hour.
The dust
Iron ore comes in three grades on this train: large fist-sized rocks, pebble-sized chunks, and what is essentially fine black powder. Regardless of grade, it goes everywhere.
By the end of the journey, travellers report being covered head to toe in dark metalite dust, their skin, clothes, and equipment uniformly blackened. Multiple masks are advisable; they will need changing. Goggles are not optional.
The temperature
The Sahara does not moderate its behaviour for tourists. Daytime temperatures regularly exceed 40°C, and the iron ore in direct sunlight becomes hot to the touch.
After sunset, the same desert that baked you in the afternoon will attempt to freeze you – night temperatures can approach zero in winter months.
Travellers riding in November to February encounter the most manageable conditions; summer journeys are advised against by everyone who has survived one.
The duration
The 704 kilometres take roughly 19 to 22 hours under normal conditions. The train stops unpredictably.
One traveller reported spending the night motionless in the desert waiting for a mechanical issue to be resolved.
There is no announcement system, no schedule posted anywhere, and no staff whose job it is to keep you informed.
The physical toll
Falls from moving ore wagons have killed people. The Wikipedia entry on the Mauritania Railway notes bluntly that death from falls is common among passengers.
The wagons have no seats, no handholds designed for human use, and no barrier between the ore pile and the open edge of the car.
A sleeping traveller who rolls at the wrong moment, or someone standing for a better view when the train lurches – the consequences are severe.
Extreme heat & cold
40°C+ by day, near-freezing at night. The ore itself acts as a heat sink, radiating warmth long after sunset – or absorbing it, depending on the season.
Toxic dust inhalation
Iron ore dust coats the lungs on every breath. Multiple industrial-grade masks are the minimum; even then, extended exposure carries health implications.
No safety infrastructure
Open wagons with no barriers, handrails, or fall protection. Falls from moving trains at 60 km/h have resulted in fatalities.
Medical isolation
The line runs through some of the remotest terrain on Earth. Medical assistance in the event of an accident or health emergency is hours away at minimum.
Legally discouraged
Mauritanian authorities have increasingly sought to restrict tourist access to the ore wagons. The train is industrial infrastructure, not a passenger service.
Sandstorms
The Sahara generates sandstorms with no warning. Riders caught in the open with no shelter face conditions that rapidly become disorienting and dangerous.
The Restrictions: Why Authorities Are Trying to Stop It
The train was designed for ore, not adventure tourism, and SNIM and Mauritanian authorities have grown increasingly uncomfortable with the attention.
The railway passed through a zone formally restricted to tourists for a decade – in January 2019, a limited tourism service resumed after a ten-year hiatus, this time using a proper passenger locomotive with two carriages on a designated tourist route that includes a visit to an iron mine.
That official tourist service exists in parallel with the informal tradition of riding the ore wagons. The two are not the same thing.
The official route is organised, supervised, and designed to give visitors a window into the railway’s industrial significance without the associated risks.
The unofficial tradition involves turning up at the station, negotiating informally, and hoping for the best.
Regulations restricting tourist access to the ore wagons are in place and have been tightened in recent years. Whether or how consistently they are enforced depends on who is on duty and what day it is.
Some travellers report being waved through without question; others describe lengthy negotiations or outright refusals.
Local guides who know the system have become something of an informal industry around the experience.
The Context: What the Locals Think About All This
One perspective that travel coverage sometimes glosses over: for the Mauritanians who ride this train out of necessity, it is not an adventure. It is transport.
The same ore dust that a foreign tourist finds photogenic coats the lungs of a merchant who has no other reasonable way home.
The same temperatures that a backpacker finds “challenging” are simply the conditions of daily life for a nomad family moving between the coast and the interior.
One travel writer who has covered the journey at length makes the point directly: while the experience can be remarkable for a voluntary adventurer with a return flight booked, it is worth remembering that for many aboard, there is nothing optional about it. The discomfort is not the point – it is the cost.
Alternatives: Adventure Without the Ambulance Risk
For travellers drawn to the idea of Africa‘s vast landscapes, industrial scale, and authentic encounters, but who prefer their adventures not to include open-wagon falls and toxic dust inhalation, alternatives exist that deliver on atmosphere without the attendant hazards.
SNIM Tourist Train, Mauritania
The same railway, organised by the operator, with passenger carriages and a stop at the iron mines. The legitimate way to see the Desert Snake in action.
Other Options in Africa:
Rovos Rail, South Africa
Described as one of the world’s most luxurious trains, traversing extraordinary landscapes from Cape Town to Dar es Salaam with rather more than two locomotives and no ore dust.
Serengeti & Maasai Mara Safaris
Kenya and Tanzania’s national parks offer profound encounters with landscapes and wildlife that require considerably less protective clothing.
Guided Desert Expeditions
Organised camel or 4WD crossings of the Sahara, including parts of Mauritania, with professional guides, proper equipment, and emergency protocols.
One of Earth’s Strangest Journeys – For Those Who Choose It Knowingly
The Iron Ore Train of Mauritania occupies a unique position in the imagination of extreme travellers. It is not a tourist attraction dressed up as something rawer – it is genuinely industrial infrastructure that some people have decided to repurpose as an experience. That distinction matters.
The spectacle is real: three kilometres of train, a sea of black ore, the Sahara unspooling in every direction, a sky full of stars after nightfall, and the occasional Bedouin camp glowing in the distance. Travellers who have done it describe it in terms that suggest it changed something in them. That is not nothing.
What is also not nothing: the falls, the dust, the heat, the legal grey area, and the fact that the people who built and operate this railway did not build it for you. The romance of the Desert Snake is genuine.
The risks are equally genuine. Anyone seriously contemplating the journey would do well to sit with both of those facts for a while before booking their flight to Nouadhibou.
