Mauritania · A Stop on the Iron Ore Train Expedition
Rising 633 metres from the desert floor, Ben Amera is the largest monolith in Africa and the second largest in the world — only behind Uluru in Australia. Located 4km from the Iron Ore Train tracks near Choum.
Rising 633 metres from the desert floor, Ben Amera is the largest monolith in Africa and the second largest in the world — only behind Uluru in Australia. Located 4km from the Iron Ore Train tracks near Choum, it is the perfect final camp before boarding the legendary train at dusk. Ben Amera is not a standalone trip — it is one of the most powerful moments on the Iron Ore Train Expedition and The Grand Mauritania.

The Giant of the Sahara
Ben Amera is the largest monolith in Africa and the second largest in the world — surpassed only by Australia's Mount Augustus, and possibly rivalling even Uluru if the rock buried beneath the sand were measured. Rising 633 metres from the flat desert floor approximately 60km west of Choum, it is a geological anomaly of staggering proportions: a single, continuous mass of granite standing in absolute isolation.
There are no roads leading to Ben Amera. The only approach is by off-road 4x4 across unmarked desert tracks, navigated by drivers who know the terrain by memory and instinct. The monolith lies just 3km from the iron ore railway — visible from the train during daylight — but reaching its base requires deliberate effort and experienced guidance.
Seven kilometres away stands its companion: Ben Aïsha, a smaller monolith that has hosted an extraordinary open-air sculpture gallery since 1999. Sixteen artists from around the world have carved works into the rock, creating a surreal art installation in one of the planet's most remote locations. The theme is peace.
Ben Amera is an inselberg — an isolated rock hill that has resisted the erosion that wore away the surrounding landscape over millions of years. Local Mauritanian legend offers a different explanation: the distinctive ‘bump’ on Ben Amera's summit is said to be the head of a woman turned to stone. Whether you prefer the geological or mythological account, the scale of this formation — visible from the iron ore train and from satellite imagery — defies easy comprehension.
The Experience
Nothing prepares you for the scale. Ben Amera rises sheer and unbroken from the desert floor — a wall of granite that seems to belong to a different planet. Walking around its base takes hours. Camping at its foot at night, with the rock face catching the last light and the first stars, is one of the Sahara's most humbling experiences.
All daySeven kilometres away, Ben Aïsha hosts dozens of stone sculptures carved by 16 international artists since 1999. The open-air gallery — dedicated to peace — sits in surreal contrast to the emptiness surrounding it. Walking among carved forms in the shadow of a monolith is unlike any art experience elsewhere.
7km awayBen Amera lies just 3km from the iron ore railway tracks. Many travellers combine a visit with the legendary train ride — camping at the monolith's base before driving to Choum to board the train to Nouadhibou. In daylight, the monolith is visible from the train wagons.
Combine tripsThere are no hotels, no auberges, no structures of any kind at Ben Amera. Camping at the base is permitted and encouraged — your tent pitched against a rock face that has stood for millions of years. The silence is total. The sky is limitless. This is camping stripped to its most elemental.
OvernightThe monolith's granite face changes colour throughout the day — pale gold at dawn, blinding white at noon, deep amber at sunset, and silver-grey under moonlight. The best light occurs in the hour after sunrise and before sunset, when the rock seems to glow from within.
Golden hoursGetting to Ben Amera is itself an adventure. The 60km drive from Choum crosses unmarked desert with no tracks, no signage, and no margin for navigation error. An experienced driver is essential — and the journey reveals a landscape that builds anticipation for the monolith's sudden, improbable appearance.
4x4 requiredArt in the Desert
In 1999, a group of sixteen artists from around the world gathered at Ben Aïsha — Ben Amera's companion monolith — to carve sculptures directly into the rock. The theme was peace. The location was chosen for its remoteness: a statement that art and human aspiration can exist even in the most unlikely places.
Today, these sculptures remain — weathering slowly in the desert wind, visited only by the few travellers who make the journey. The juxtaposition of carved human forms against raw geological immensity creates something genuinely moving: a reminder that wherever humans go, they leave meaning behind.
“There are no roads leading to Ben Amera. With an experienced driver, however, the trip can be made off-road without any problems.”— Chingi Tours, Mauritania
Before You Go
Ben Amera lies 60km west of Choum, accessible only by off-road 4x4 across unmarked desert. No roads, no tracks, no signage. An experienced Yolo driver navigates by memory and landmarks. The drive takes approximately 2 hours.
All camping equipment is provided by Yolo. Bring sun protection, sturdy walking shoes, a headlamp, warm layers for the night, and plenty of water. A camera with wide-angle lens is essential to capture the monolith's scale.
A full Ben Amera expedition typically runs 7 days, combining the monolith visit with the iron ore train ride, Choum, and often extending to Nouadhibou. Two nights at Ben Amera is recommended.
Cooler months are essential for comfort at this remote site. Summer temperatures can exceed 45°C with no shade. Winter nights are cold — bring warm layers. The light in November and March is exceptional.
No technical climbing required, but this is genuinely remote travel with no infrastructure. Basic fitness for walking on sand and rock. The off-road drive can be bumpy. Not suitable for those who need access to facilities.
Most Ben Amera visitors continue to Choum to board the Iron Ore Train to Nouadhibou, creating one of Mauritania's most iconic combined experiences. Yolo arranges seamless logistics between the monolith camp and train departure.
