Mauritania Iron Ore Train Guide

The Iron Ore Train runs between Zouérat — a remote mining city in the far north of Mauritania — and Nouadhibou, the country's main Atlantic port. The full route covers 704 kilometres, making it one of the longest train journeys in Africa.

The railway is operated by SNIM (Société Nationale Industrielle et Minière), Mauritania's state mining company. Its purpose is industrial: loaded trains carry iron ore from the mines near Zouérat west to the port at Nouadhibou for export. Returning empty trains head east. Passengers — in the open ore wagons or the rear passenger carriage — travel at the railway's convenience, not their own.

The main stops along the route are Zouérat in the northeast, Tmeimichat roughly mid-route, Choum (where most travellers board), and then the long final run through open desert to Nouadhibou. Between Choum and Nouadhibou — approximately 460 kilometres — there are no visible towns, no roads, and no infrastructure of any kind. Flat Saharan gravel plain, iron ore dust, and an immense sky.

If you want to join an organized expedition, you can book a locally organized Mauritania Iron Ore Train tour — we handle transport, guides, Choum boarding, and all desert logistics.

Most travellers board at Choum. It sits at the natural end of the classic Adrar desert circuit — Nouakchott to Atar to Chinguetti to Choum — making it the practical starting point for the vast majority of visitors who include the Iron Ore Train as part of a wider Mauritania itinerary.

Boarding at Zouérat gives you the full 704-kilometre run but adds a two-day drive each way through very remote terrain in the Tiris Zemmour region. For experienced desert travellers who want the complete journey, it is a legitimate option. For most first-time visitors to Mauritania, Choum is the right decision.

Boarding at Tmeimichat is occasionally mentioned but rarely practical. It is a featureless waypoint with no accommodation, and timing a vehicle arrival to coincide with the train is significantly more difficult than at Choum.

Every Iron Ore Train has a passenger carriage attached to the rear. Travellers choose between this carriage or the open iron ore wagons — and the choice defines the experience.

The open wagons are free on the westbound (empty) run from Zouérat or Choum to Nouadhibou. They have no roof, no seats, and no protection from wind or dust. You sit or lie on iron ore residue coating the wagon floor — everything you carry will be covered in dark red-black dust by journey's end. The experience in return is extraordinary: the scale of the open desert, the train snaking through a flat landscape, the night sky over the Sahara from inside a slowly moving steel box. These are moments that stay with travellers permanently.

The passenger carriage costs between 2,000 and 5,000 MRU per person (roughly €5–12), negotiated at the station. It has benches and partial shelter from the wind. Iron ore dust still reaches it. It is considerably less dramatic than the wagons but a sensible option for travellers with dust-related health concerns, those with young children, or anyone who prefers the journey with reduced physical exposure.

Neither option is conventionally comfortable. The carriage is a practical choice. The wagons are the real Iron Ore Train experience.

There is no public timetable for the Iron Ore Train. SNIM runs it on a mining schedule that changes daily according to operational requirements — ore loading volumes, maintenance windows, and port logistics at Nouadhibou. Departures from Zouérat are broadly in the early morning or late afternoon but shift, sometimes significantly, from day to day.

This means you cannot plan to arrive at Choum on a specific day and board within a few hours. Travellers using a local operator will typically have a contact monitoring the train's expected arrival window — local contacts near the station often have advance notice of when the train left Zouérat, which gives a rough estimate of when it will reach Choum.

Budget two nights near Choum rather than planning to arrive and board the same day. The wait is part of the Iron Ore Train experience. Choum itself — the edge of the open desert, the silence, the local rhythm — is worth a night in its own right.

From Choum to Nouadhibou, the journey typically takes 8 to 12 hours. The full run from Zouérat covers 704 kilometres and takes 14 to 20 hours, depending on loading stops, maintenance halts, and the operational pace on that particular day.

These are realistic estimates rather than guaranteed windows. The train does not run to a schedule, and delays of several hours occur. A journey beginning at Choum in the afternoon may arrive in Nouadhibou at dawn, at midnight, or at midday the next day. The night portion — typically 4 to 8 hours regardless of departure time — will be cold in the open wagons even in October and November.

When planning onward connections from Nouadhibou, budget for the longer end of the duration range. Do not book non-refundable transport for the day immediately after your expected arrival.

The Iron Ore Train has no facilities on board — no food, no water, no toilets, no shelter in the wagons. Everything you need for the journey must be sourced in Atar or Choum before boarding.

Read the full Iron Ore Train packing list for a detailed breakdown of every item, why it matters, and what to buy before you leave.

• FFP2 or N95 dust mask — bring 2 to 3 per person; fabric bandanas do not filter iron ore particulate
• Wraparound goggles or sealed sunglasses — iron ore dust in unprotected eyes is painful within minutes
• Sleeping bag rated to at least 5°C — even October nights in an open wagon with wind chill are genuinely cold
• Windproof outer jacket — wind in the open wagons is constant and cuts through light layers
• Thermal base layer for the night portion of the journey
• Minimum 3 to 4 litres of water per person — nothing is available on board
• Food for the full journey: fresh bread, dates, tinned fish with pull-ring opening, nuts, dried fruit
• Head torch for night boarding and navigating the wagons after dark
• Dark-coloured clothing throughout — iron ore dust stains everything permanently
• Small top-access daypack with water and food kept within reach at all times

October to March is the riding season. The heat has broken, the desert light is exceptional, and the journey is physically manageable.

October and November are the best months: daytime temperatures are warm and pleasant in the desert, nights are cool but not severe, and the light quality — especially the long golden hours of sunrise and sunset viewed from an open wagon — is excellent for photography. These months also coincide with peak demand for Mauritania travel, so booking guides and logistics early matters.

December through February brings cold nights. In the open wagons in December or January, overnight temperatures combined with wind chill can reach genuinely uncomfortable levels. This is manageable with the right sleeping gear but requires thorough preparation. The journey is no less extraordinary in winter — arguably more so under clear cold skies.

March is a reliable shoulder-season choice: comfortably cool, good light, and slightly less competition for guides and accommodation.

Avoid May through September. Iron ore wagons in full Saharan summer — ambient temperatures of 40–45°C and exposed metal heated by direct sun — create a serious heat risk. SNIM does not restrict passengers, but the open wagon experience in this period is dangerous rather than merely uncomfortable.

Choum is not accessible by public transport. The approach from Atar — the main gateway town for the Adrar region — requires a 4×4 vehicle across an unmarked desert piste. The drive takes approximately 3 to 4 hours depending on conditions and the route taken.

The piste runs through open flat desert and low rocky terrain with no road signs, no fuel stops, and no mobile network for most of the route. The journey requires a driver who knows the track.

For most travellers, Choum is reached as the final stop on the Adrar circuit: Nouakchott to Atar (roughly 9 hours on the main highway), Atar to Chinguetti (1.5 hours), a day or two in Chinguetti or the surrounding desert, then the desert drive to Choum. This sequence places the Iron Ore Train naturally as the finale of the inland portion before the Atlantic coast.

If travelling independently, hiring a 4×4 with driver in Atar is possible but requires local contacts to find a reliable driver who knows the Choum piste. Our tours handle the full Atar-to-Choum transfer as part of the itinerary.

Nouadhibou is Mauritania's second city and main port. After the train arrives, you will be at the railway station on the edge of town — at an hour that is largely unpredictable. It may be dawn, midnight, or anything in between.

The city has accommodation ranging from basic guesthouses to comfortable hotels. The surrounding area is worth a full day: Banc d'Arguin National Park lies to the south, the famous ship wreck beach at Baie du Lévrier is nearby, and the local fish market reflects the city's identity as a working Atlantic port.

For travellers continuing north, Nouadhibou is the departure point for the overland crossing into Western Sahara and Dakhla. This is one of the classic West African overlanding routes. Our Dakhla Entry tour covers this crossing as a standalone option from Mauritania.

For travellers returning south, shared taxis and private vehicles connect Nouadhibou to Nouakchott in approximately 7 hours. Our tours manage all Nouadhibou logistics — accommodation on arrival, rest time, onward transport, and the Dakhla border crossing where required.
