The name Kitum means “place of ceremony” in the Maasai language, and the cave has been a sacred site for local communities for generations. It is a place where the mountain itself holds salt — and where elephants, for thousands of years, have gone underground to mine it.
Kitum Cave is one of five named “elephant caves” on Mount Elgon, an extinct shield volcano that straddles the border between Uganda and Kenya. It is the most famous of them all — a 200-metre-deep tunnel into the side of the mountain, carved not by water or lava, but by the tusks of generations of elephants. It is also, for reasons that have made it infamous in scientific literature, one of the most dangerous places in Africa for a different reason entirely.
This is the complete guide to Kitum Cave — the elephants, the salt, the geology, the disease, and everything you need to know before you visit.
Where Is Kitum Cave?
Kitum Cave is located on the Kenyan side of Mount Elgon, in Mount Elgon National Park, in Trans Nzoia County, approximately 30 kilometres from the town of Kitale. It sits at an elevation of approximately 2,400 metres on the eastern flank of the mountain, not far from the border with Uganda.
The cave extends approximately 200 metres into the side of Mount Elgon, with an entrance tunnel about 40 metres long and an entrance width of approximately 50 metres. The interior includes large chambers with ceilings up to 4 metres high, and deep crevasses that have claimed the lives of young elephants and other animals over the centuries.

The Geology: A Cave Unlike Any Other
Formed in Volcanic Ash
Most caves form in limestone, carved by the slow dissolution of rock by acidic water. Kitum Cave is different. It is a karst cave formed in pyroclastic volcanic rock — the solidified debris of volcanic eruptions, including ash, tuff, and agglomerate.
Mount Elgon itself is an extinct shield volcano that first erupted approximately 24 million years ago. During its active period, rivers of basaltic lava created an exceptionally high dome that may have once stood taller than Kilimanjaro before erosion reduced it to its current height. The mountain still has the largest volcanic base in the world, covering over 4,000 square kilometres.
The rock of Kitum Cave is a volcanic agglomerate — a mass of small and large blocks of old solid lava, bound together by fine-grained volcanic ash. This rock is rich in sodium, calcium, magnesium, and phosphates — remnants of the ancient lava that the elephants come to mine.
Carved by Elephants?
For decades, geologists debated how Kitum Cave formed. Some suggested wave action, others running water, others gas bubbles in lava. But the most compelling explanation — and the one now widely accepted — is that the cave was created primarily by elephants.
The hypothesis was first proposed in the early 1980s by researchers studying Mount Elgon’s elephants. A rough calculation estimated the volume of Kitum Cave at 5 million litres and, assuming a conservative excavation rate of one litre of rock per week, suggested it would have taken 100,000 years for elephants to carve the cave. Later measurements showed the volume was even larger — between 20 and 40 thousand cubic metres — but also that the excavation rate was likely underestimated.
One observation recorded a young bull elephant at a Kenyan safari lodge ingesting between 13.8 and 20.7 kilograms of salty soil in 45 minutes. If even a fraction of that rate applies to the elephants of Kitum, the cave could have been carved in a fraction of the original estimate. Today, the elephant speleogenesis hypothesis — that elephants, over thousands of years, excavated the cave by mining and ingesting the salt-rich rock — is considered “entirely plausible”.
Not a Lava Tube
It is worth noting what Kitum Cave is not. Despite its location on a volcano, it is not a lava tube. Lava tubes form when the surface of a lava flow solidifies while molten rock continues to flow beneath it, eventually draining away to leave a hollow tunnel. Kitum Cave shows none of the characteristic features of a lava tube. It is a karst cave in volcanic rock — a geological rarity.
The Elephants: The World’s Only Underground Miners
The Salt Miners of Mount Elgon
The elephants of Mount Elgon are the only elephants in the world known to excavate for salt in underground caves. They enter the caves at night, navigating pitch blackness by feeling with their trunks for routes worn over thousands of years by their ancestors.
Once inside, they use their tusks to score the salt-rich walls, prising away lumps of rock to consume. One elephant can excavate up to 20 kilograms of salt rock in a single night. The practice has shaped the elephants themselves: the elephants of Mount Elgon have particularly stubby tusks, worn down by generations of mining.
Why They Mine
The elephants need salt. Mount Elgon is very poor in minerals due to the heavy rainfall that sweeps nutrients out of the soil. Deep in the crevices of caves like Kitum lie valuable seams of sodium-rich rock that the elephants need for their diet.
A study examining samples from the cave walls found they contained more than 100 times the amount of sodium per gram than the average level found in plants. For elephants that would otherwise struggle to find sufficient minerals, the caves are an essential resource.
A Learned Tradition
The behaviour is not instinctive. It is passed down from generation to generation — a unique tradition that exists only on Mount Elgon. Calves accompany their mothers into the caves, learning the routes and the technique of scraping the walls. The elephants have been visiting these caves for centuries, possibly even millennia, and over time they have modified and enlarged the caves, digging deeper and deeper into the mountain.
Other Animals
Elephants are not the only creatures that visit Kitum Cave. Buffaloes, bushbucks, and hyenas come to the cave to eat the salt left behind by the elephants. The cave is also home to fruit bats and insect-eating bats, whose guano accumulates deep inside.
The Disease: The Most Dangerous Place on Earth
The Marburg Virus
Kitum Cave has a darker claim to fame. It is a natural reservoir for the Marburg virus, a deadly pathogen closely related to Ebola that causes severe viral haemorrhagic fever in humans. The virus is carried by Egyptian fruit bats (Rousettus aegyptiacus) that roost in the cave.
The Marburg virus has a fatality rate of over 88% in some outbreaks, making it one of the most lethal infectious diseases known to science. There is no approved vaccine or antiviral treatment. The virus is transmitted to humans through close contact with infected bodily fluids.
The 1980 Case: Charles Monet
The first documented case linked to Kitum Cave occurred in January 1980. A Frenchman and self-taught naturalist named Charles Monet visited the cave, drawn by his love of animals and curiosity about Kenya’s natural attractions.
Seven days after his visit, he developed a throbbing pain behind his eyeballs. Within three days, he was vomiting intensely, became strangely passive, and his face “lost all appearance of life”, according to Richard Preston’s account in The Hot Zone. He took a plane to Nairobi, vomiting the entire way. He died shortly after arriving at the hospital, and the virus subsequently spread to a doctor who attended him.
The 1987 Case: The Danish Boy
In 1987, a 15-year-old Danish boy who lived in Kenya visited Kitum Cave and subsequently died of Marburg virus. His case confirmed that the cave was an ongoing source of the virus, not a one-time anomaly.
What Makes Kitum So Dangerous
Kitum Cave’s danger lies in its unique combination of factors. The cave is dark, enclosed, and filled with bats — ideal conditions for a virus to circulate. The elephants that enter the cave to mine salt disturb the bats and their guano, potentially aerosolizing the virus. And humans who visit the cave breathe the same air, walk the same ground, and touch the same surfaces.
The cave has been described as “the most dangerous place on Earth” by some media outlets, and while that label is sensationalized, the underlying concern is real. Kitum Cave is one of the few places in the world where a known lethal virus reservoir is readily accessible to tourists.
Current Safety Measures
Despite the risks, Kitum Cave remains open to visitors. The Kenya Wildlife Service (KWS) manages the cave and requires all visitors to be accompanied by a licensed guide — a mandatory safety requirement. Visitors are advised not to touch the cave walls, not to disturb the bats, and not to enter the cave if they have open wounds or are immunocompromised.
There is no vaccine for Marburg, and post-exposure treatment is limited to supportive care. Travellers who visit Kitum Cave should be aware of the symptoms — fever, headache, muscle pain, and bleeding — and seek immediate medical attention if they develop within 21 days of their visit.
Visiting Kitum Cave: A Practical Guide
Getting There
Kitum Cave is accessed from the Kenyan town of Kitale, approximately 30 kilometres away via the Endebess Road. The drive is on a rough murram road, and a 4×4 vehicle is strongly recommended, particularly during the rainy season. The trailhead is at Chorlin Gate, where visitors pay park entry and hire a guide.
The round trip to Kitum Cave is approximately 4 kilometres, starting at an elevation of 2,400 metres and climbing through montane forest, bamboo, and Podocarpus woodland. The walk takes approximately 2 hours at a leisurely pace.
Park Fees (2026)
| Visitor Category | Adult | Child |
|---|---|---|
| Foreign Non-Residents | USD $50 | USD $25 |
| Kenyan Citizens/Residents | Reduced rate | Reduced rate |
Payment must be made in advance through the eCitizen platform (MPesa or Visa). Cash is not accepted at the gate.
Guide Fees
A licensed guide is mandatory for all cave visits. The guide fee is approximately 1,720 Kenyan Shillings (about USD $13) for up to 4 hours of guiding.
Best Time to Visit
The dry seasons — January to February and June to September — offer the most comfortable hiking conditions, with firmer trails and clearer weather. The wet season brings lush green landscapes but muddy, slippery trails, particularly through the bamboo zone.
Time of day: Early morning is best for wildlife viewing, as the elephants typically enter the cave at night and leave at dawn. Arriving at the cave at dawn offers the best chance of seeing them emerge.
What to Bring
-
Sturdy hiking boots — the trail can be muddy and slippery, especially through the bamboo zone
-
A rain jacket — the weather can change quickly at this altitude
-
A torch or headlamp — essential for exploring the cave interior
-
Warm layers — the cave is cool, and mornings at 2,400 metres can be chilly
-
Insect repellent
-
Water and snacks
-
Cash — for guide fees and tips (park fees must be paid in advance online)
-
A face mask — recommended for the bat-inhabited sections of the cave
What to Expect Inside
The entrance tunnel is 40 metres long and opens into a large chamber with ceilings up to 4 metres high. The walls are scarred and furrowed by tusk marks — evidence of thousands of years of elephant mining. In places, the walls are covered in moss that appears silver in the beam of a headlamp.
The floor is smooth, worn by the feet of countless elephants over millennia. Deep inside, there are crevasses — some of them deep enough to have claimed the lives of young elephants that fell in and died. The air smells of bat guano and damp volcanic rock.
The cave extends approximately 200 metres into the mountain, but visitors are generally restricted to the main chamber and the entrance tunnel. Deeper sections are closed for safety reasons.
Beyond Kitum: The Other Elephant Caves of Mount Elgon
Kitum is not the only elephant cave on Mount Elgon. The mountain has five named elephant caves, each with its own character and accessibility.
Makingeny Cave is the most spectacular of the Mount Elgon caves, with a waterfall pouring from its mouth and bats roosting deep inside. It is larger than Kitum and equally impressive.
Chepnyalil Cave is another of the named caves, accessible to visitors and known for its salt deposits.
Ngwarisha Cave and Kitengeto Cave are also part of the Mount Elgon cave system, though they are less frequently visited.
On the Ugandan side of the mountain, several caves are accessible on day hikes from the Sipi Falls area and the Kapkwai Forest Exploration Centre, including Kapkwai Cave, Tutum Cave, and Khaukha Cave on Wanale Ridge.
Conservation: The Elephants of Mount Elgon
A Declining Population
The elephants of Mount Elgon are unique in the world — the only elephants known to excavate for salt in underground caves. But their population is in steep decline.
The elephants of Mount Elgon National Park are “the precious remnants of the once numerous herds that roamed the area around the extinct volcano”. They have all but disappeared from the Ugandan side of the border, and only a few hundred still cling on in the forests of the Kenyan side, surviving human hunters and deforestation thanks to the protection of national park rangers.
Human-elephant conflict has been a major driver of the decline. Farmers plant crops among the woodland’s sapling trees, and elephants find the edible plants a tempting addition to their diet — leading to conflict that endangers both elephants and local people.
Conservation Efforts
The preservation of these unique animals is the focus of strenuous conservation efforts. The Mount Elgon Elephant Conservation and Research Programme (MEECRP) has studied the elephants and their cave-mining behaviour for decades, providing the scientific foundation for conservation planning.
The Kenya Wildlife Service protects the elephants within Mount Elgon National Park, and community outreach programmes are working to reduce human-elephant conflict outside the park boundaries.
The Verdict: A Cave Like No Other
Kitum Cave is not simply a cave. It is a place where elephants mine for salt in pitch darkness. Where the walls are scarred by tusks over thousands of years. Where the rock itself was formed by volcanic eruptions 24 million years ago. And where a virus with a 90% fatality rate lurks in the bats that roost in its depths.
It is a place of extraordinary natural wonder and genuine danger. It is a place where the boundaries between geology, wildlife, and human health blur in ways that are rarely seen anywhere else on Earth. And it is a place that, for all its perils, remains one of the most remarkable destinations in East Africa.
For the adventurous traveller willing to follow the elephant tracks into the darkness, Kitum Cave offers something rare: a journey into the heart of a mountain, along a path carved by the tusks of giants, into a world that exists nowhere else on Earth.
