What Is Actually Happening to the Rwenzori’s Ice
The Rwenzori Mountains still have glaciers. As of the most recent field and satellite surveys, a shrinking body of ice remains on Mount Stanley, clinging to the upper Stanley Plateau just below Margherita Peak. That ice has declined dramatically over the last century, and the pace of loss has accelerated in the past two decades. Scientists attribute this decline primarily to a sustained rise in regional air temperature, combined with long-term shifts in precipitation and cloud cover, rather than to any single event or season.
This “Why the Rwenzori Glaciers are Dissappearing?” page sets out to explain that process carefully, using the same body of published glaciological research, satellite monitoring, and field expedition data that scientists themselves rely on. We are not going to tell you the glaciers vanish tomorrow, because that is not what the evidence shows. We are also not going to tell you they are safe, because the evidence does not support that either. What follows is the science, stated as plainly and precisely as we can manage, because the Rwenzori’s glaciers remain one of the most remarkable natural features on the African continent, and understanding what is happening to them makes trekking here mean something more than reaching a summit.

What Are the Rwenzori Glaciers?
A glacier is, at its simplest, a persistent body of dense ice that forms wherever snow accumulates faster than it melts over many years, compacting under its own weight into ice that then flows slowly downhill under gravity. What matters for glacier formation is not how cold a place feels at sea level, but whether its highest terrain sits above the altitude at which temperatures remain reliably at or below freezing, a threshold glaciologists call the equilibrium line altitude, or ELA.
This is why glaciers can exist directly on the Equator. Air temperature falls with altitude at a fairly predictable rate, roughly 6 to 6.5°C for every 1,000 metres climbedrate, roughlyof how close a mountain sitsmeters climbed, regardlessquator, the freezing level typically sits somewhere between 4,500 and 5,100 meters above sea level. Any peak that reaches above that line can, in principle, sustain permanent ice, no matter its latitude. Altitude, in other words, matters far more than latitude in determining where glaciers form, which is exactly why the Rwenzori, Kilimanjaro and Mount Kenya — all essentially on the Equator — are three of the very few places on the planet where equatorial glaciers exist at all.
The Rwenzori are unique among Africa’s glaciated peaks for one further reason: unlike Kilimanjaro and Mount Kenya, which are ancient volcanoes, the Rwenzori are a non-volcanic, fault-block mountain range, uplifted bodily along the rift faults of the Albertine Rift. Their jagged, glacially carved summit ridges and steep cirques hold onto snow and ice in a way that a broad volcanic dome like Kilimanjaro’s summit plateau does not, and the range sits in an unusually wet corner of East Africa, drawing heavy, near-daily cloud and precipitation off the Congo Basin. That combination of extreme altitude, sharp alpine relief and abundant moisture is what allowed the Rwenzori to sustain a genuine, if small, tropical glacier system for millennia, and it is also, as later sections explain, part of why that system is now so sensitive to a changing climate.
How the Glaciers Formed
The Rwenzori’s glaciers are the surviving remnant of a much larger ice system that has waxed and waned repeatedly over the mountain’s geological history. During the colder phases of the Pleistocene ice ages, glaciers on the Rwenzori extended far below their present limits, carving the U-shaped valleys, moraine ridges and cirque basins that still shape the trekking routes today — the wide, glacially scoured Namusangi and Bujuku valleys, the string of glacial lakes along the Kilembe trail and Central Circuit trails, and the amphitheatre-like basins beneath Stanley and Baker are all direct legacies of that older, more extensive ice.
The modern glaciers are younger and far smaller, built up through the same basic process anywhere in the world: snow falling at high altitude accumulates faster than it melts, and successive snow layers compress the layers beneath them, squeezing out air and slowly recrystallising loose snow into dense, blue-tinted glacial ice. Over enough years, that accumulated ice becomes thick and heavy enough to begin flowing slowly downhill under its weight, deforming and cracking as it moves—the process that produces crevasses. Like most of the world’s mountain glaciers, the Rwenzori’s ice reached its most recent maximum extent during the cooler global climate period known as the Little Ice Age, roughly the seventeenth to mid-nineteenth centuries, before beginning the long retreat that this guide documents in detail below. Every trekker who crosses the moraine fields, glacial lakes and polished bedrock on the approach to Margherita Camp is, in effect, walking across the historical footprint of a much larger glacier than the one that remains today.
Where Are the Glaciers Today?
At the start of the twentieth century, six of the Rwenzori’s principal peaks carried glaciers: Mount Stanley, Mount Speke, Mount Baker, Mount Emin, Mount Gessi, and Mount Luigi di Savoia. By the 1990s, sustained retreat had already reduced the number of glaciated massifs to three: Mount Stanley, Mount Speke, and Mount Baker, which are the only peaks in the range that are high and sheltered enough to retain permanent ice. Satellite analysis from 2021–2022 found that Mount Stanley alone accounted for roughly 92 percent of the Rwenzori’s remaining glacier area, with Speke and Baker holding only small, fragmentary remnants. Field expeditions conducted since then, most recently in 2024, report that Mount Baker and Mount Speke have now lost their glaciers entirely, leaving Mount Stanley, specifically the Stanley Plateau, immediately below Margherita and Alexandra peaks — the last continuously glaciated ground in the range.
For trekkers, this concentration of the remaining ice matters directly. The standard Kilembe Trail and Central Circuit routes to Margherita Peak both approach and cross this same Stanley Plateau glacier on summit day, via Elena Hut and Scott Elliot Pass. It is the only glacier crossing built into any standard Rwenzori trekking itinerary today; routes that summit Mount Speke or Mount Baker instead now involve largely ice-free rock and scree rather than the glacier travel those peaks required a generation ago.
Why Are the Glaciers Disappearing?
No single cause explains the Rwenzori’s glacier retreat. Tropical glaciers respond to a unique mix of factors that are different from the seasonal summer-melt and winter-accumulation cycle that drives glaciers at higher latitudes, and understanding each factor separately helps explain both the speed and pattern of the ice loss recorded here.
Rising Air Temperatures
Warmer air raises the altitude of the freezing line, shrinking the area of the mountain cold enough to sustain permanent ice and directly increasing melt rates at the glacier surface and margins. Regional warming trends recorded across East Africa over the twentieth and twenty-first centuries have pushed the equilibrium line altitude upward, meaning an ever-smaller portion of the Rwenzori’s highest terrain now sits reliably above freezing year-round.
Changes in Rainfall
Glaciers need snowfall at altitude to replenish the ice lost to melting each year. Research into the onset of East African glacier retreat points to a documented shift toward a drier regional climate beginning in the late nineteenth century, which reduced the snow available to replace what was already being lost — a precondition for retreat that predates, and compounds, the more recent temperature-driven losses. More recent studies of the wider socio-ecological system around the Rwenzori note that rainfall variability, rather than a simple decline, continues to interact with warming to influence the mountain’s overall moisture budget.
Changes in Cloud Cover
Cloud cover plays an unusually large role in tropical glacier mass balance because it governs how much solar radiation reaches the ice surface and how much heat the glacier radiates back to a clear night sky. Reduced or altered cloud cover changes this radiation balance, and tropical glaciology research going back to the work of Georg Kaser and colleagues has repeatedly shown that shifts in atmospheric moisture and cloudiness can influence tropical glacier melt as strongly as, or more strongly than, air temperature alone — a key difference from mid-latitude glaciers, where temperature is usually the dominant driver.
Reduced Snow Accumulation
Every glacier survives on the balance between what it gains each year through snowfall and what it loses through melting and sublimation. When accumulation falls, whether because of reduced precipitation, a higher freezing line that turns more of that precipitation to rain rather than snow, or both, the glacier’s annual mass balance turns negative, and the ice body thins and retreats even without any further change in temperature.
Long-Term Climate Trends
Individual warm years or dry seasons do not, on their own, explain a century of measured retreat. What the scientific record shows is a sustained, decades-long trend: rising average temperatures, a documented shift in regional moisture patterns, and repeated satellite and field observations recording the same direction of change across multiple independent studies and methods. It is this long-term consistency, not any single season, that constitutes the scientific case for climate change as the primary driver of Rwenzori glacier retreat.
A Timeline of Glacier Retreat
Period | What the Evidence Shows |
Pleistocene ice ages | Extensive glaciation carves the Rwenzori’s characteristic U-shaped valleys, cirques, and moraine systems, far below the elevation the ice occupies today. |
c. 1600s–1850s (Little Ice Age) | Global glacier advance reaches its most recent Holocene maximum in most mountain ranges worldwide; the Rwenzori’s ice is understood to have reached its largest recent extent during this broad period. |
Late 19th century | Research points to a shift toward a drier regional climate across East Africa around this time, marking the documented onset of sustained glacier retreat. |
1906 | The Duke of the Abruzzi’s Italian expedition completes the first detailed scientific mapping of the Rwenzori’s peaks and glaciers, later used by glaciologist Georg Kaser to reconstruct a glacier area of roughly 6.5 km² across the range. |
1955 | Aerial photographic surveys allow the first photogrammetric mapping of the glaciers, recording an area of approximately 3.2 km²—roughly half the 1906 extent. |
1987 | Satellite-based analysis by researchers at Texas A&M University records a glacier area of approximately 2.55 km². |
Early 1990s | Field surveys by Georg Kaser, comparing historical maps against direct observation, record an area of roughly 1.7 km² and confirm that only three of the range’s six historically glaciated peaks — Stanley, Speke and Baker — remain glaciated. |
2003–2006 | Updated satellite analysis records the glacier area down to approximately 1.31 km². |
c. 2010 | A synthesis of East African tropical glacier research concludes that more than 80% of the region’s early-twentieth-century glacier area has already disappeared. |
2021–2022 | High-resolution satellite analysis published in the peer-reviewed journal Environmental Research: Climate (2024) records total Rwenzori glacier area at approximately 0.38 km², with Mount Stanley accounting for around 92% of what remains. |
2024 | A field expedition led by Project Pressure, in partnership with UNESCO and the Uganda Wildlife Authority, uses drone photogrammetry, GPS survey and ground-penetrating radar to produce the first detailed 3D model of the Stanley Plateau glacier, recording a 29.5% loss of surface area since 2020 and confirming that Mount Speke and Mount Baker no longer retain glacier ice. |
Scientific Evidence for Glacier Retreat
The case for Rwenzori glacier retreat does not rest on any single source. It is built from multiple independent lines of evidence, gathered using different methods over more than a century, that all point in the same direction.
Satellite Imagery
High-resolution optical satellite data has been used repeatedly since the 1980s to map glacier boundaries from above, most recently in the 2024 Environmental Research: Climate study, which used 2021–2022 imagery to measure glacier extent across Kilimanjaro, Mount Kenya and the Rwenzori using a consistent, comparable methodology.
GPS and GNSS Field Measurement
Ground survey teams have used precise GPS positioning to map glacier margins, ice thickness and terminus position directly on the mountain, providing ground-truth data against which satellite measurements can be checked and calibrated.
Field Expeditions and Ground-Penetrating Radar
The 2024 Project Pressure expedition, conducted with UNESCO and the Uganda Wildlife Authority, used drone photography, GPS survey, and ground-penetrating radar to create the first detailed three-dimensional model of the Stanley Plateau glacier, allowing scientists to measure not only its shrinking surface area but also its internal ice thickness and structure.
Repeat Photography
Comparing modern photographs against historical images, including photographs from the Duke of the Abruzzi’s 1906 expedition and subsequent twentieth-century surveys, provides a visually direct, publicly accessible record of how dramatically the ice extent has changed over more than a century.
Peer-Reviewed Research
Findings from these methods have been published and cross-checked in the peer-reviewed literature, including Kaser and Osmaston’s foundational 2002 book Tropical Glaciers (Cambridge University Press), and the 2024 study by Hinzmann, Mölg, Braun, Cullen, Hardy, Kaser and Prinz in Environmental Research: Climate, giving the Rwenzori’s glacier record the same level of scientific scrutiny applied to Kilimanjaro and Mount Kenya.
How Glacier Retreat Changes the Landscape
As the Stanley Plateau glacier thins and its margins retreat, the terrain beneath and around it visibly reshapes. Newly exposed bedrock, still polished and scored by the recently melted ice, appears at the glacier’s retreating edges. Meltwater from the shrinking ice feeds into the network of alpine lakes along both the Kilembe trail and Central Circuit routes, including Lake Kitandara and the smaller tarns near Bugata Camp, but these lakes are mainly sustained by the Rwenzori’s exceptionally heavy rainfall rather than by glacial melt alone. Loss of the ice’s structural support and changes to freeze-thaw cycles on newly exposed rock faces are understood, in mountain environments generally, to increase the likelihood of localised rockfall on steep slopes near retreating glacier margins, and guides operating on the mountain report having to adjust their exact route lines around the Stanley Plateau from season to season as the ice thins and crevasse patterns shift.
Effects on Wildlife and Vegetation
The Rwenzori’s five vegetation zones — Afro-montane forest, bamboo, heather-rapanea, Afro-alpine moorland and the bare rock and ice zone — are each defined by temperature, rainfall and, at the upper limit, proximity to permanent ice and snow. As the glaciated area shrinks and the effective cold-zone footprint contracts, ecologists broadly expect species and plant communities adapted to the coldest, highest ground to face a narrowing habitat over time, a pattern documented on other tropical mountains as their glaciers and permanent snowlines retreat. It is important to be precise about what is and is not yet well established for the Rwenzori specifically: comprehensive, mountain-specific studies tracking measurable shifts in Afro-alpine species ranges or population changes directly attributable to glacier loss remain limited, and this guide will be updated as that research develops. What is well documented is that meltwater and heavy orographic rainfall together sustain the alpine lakes, bogs and tussock grassland that define the Afro-alpine moorland zone crossed on Days 3 and 4 of the Kilembe Trail, and that this zone’s water balance is sensitive to the same long-term precipitation and cloud trends discussed above.
Effects on Local Communities
For the Bakonzo people who have lived around the Rwenzori for centuries, the mountain’s ice carries a significance well beyond hydrology or tourism. Traditional Bakonzo belief holds that Kithasamba and Nyabibuya, central figures in local cosmology, dwell within the mountain’s ice, and the visible retreat of the glaciers has been described by Uganda Wildlife Authority staff working in the region as a matter of real cultural and spiritual loss, not only an environmental one.
The practical effects on surrounding communities are shaped by many interacting factors, of which glacier retreat is one. The rivers that rise in the Rwenzori’s high country, including the Nyamwamba, are mainly fed by the range’s exceptional rainfall rather than by glacial melt alone, but recent research has linked changes to the mountain’s overall water balance, including rainfall, cloud cover, and ice loss, to increased flood and landslide risk in the valleys below, which directly affects agriculture and settlement in the districts around Kasese and Bundibugyo. Tourism and trekking livelihoods, meanwhile, are tied closely to the ongoing presence of visible glacial ice as part of the Rwenzori’s appeal; while the range’s forests, wildlife, waterfalls and vegetation zones remain extraordinary in their own right regardless of glacier extent, the loss of the ice is nonetheless a loss to the destination’s identity that the local guiding and tourism economy is actively adapting around.
What Does This Mean for Trekkers?
This is the question most people arrive at this page to answer, so here is the direct, current-as-of-writing picture.
Can I still see glaciers?
Yes. The Stanley Plateau glacier, immediately below Margherita and Alexandra peaks, remains in place today and is crossed on summit day of both the Kilembe Trail and Central Circuit routes to Margherita Peak. It is smaller, thinner, and more fragmented than it was even five years ago, but it is still very much there to be seen and, with proper equipment and guidance, walked across.
Is Margherita Peak still glaciated?
The immediate summit approach to Margherita Peak still crosses genuine glacier ice on the Stanley Plateau, making this one of the very few treks in Africa, alongside a small number of routes on Mount Kenya, where crampon-and-rope glacier travel remains part of a standard, non-technical-climbing-grade summit itinerary.
Has the route changed?
Yes, gradually. As the glacier has thinned and retreated, the exact line guides take across the Stanley Plateau, and the balance between ice travel and rock scrambling has shifted from what it was a generation ago. Guides reassess the safest line across the glacier each season based on current crevasse patterns and ice thickness.
Do I still need crampons?
Yes. Crampons, an ice axe, and rope remain standard, necessary equipment for the Stanley Plateau glacier crossing on summit day, and our itineraries include this technical equipment and the trained guides to use it safely.
Is glacier travel different today than it was ten or twenty years ago?
Yes, in two respects. The area of ice to be crossed is smaller, and the terrain around its margins, thinning ice, occasional crevasses, and, in places, unstable rock recently exposed by retreat, requires more careful, conservative route-finding than it once did. This is precisely why experienced, mountain-specific guiding and a strict, weather-based turnaround time remain essential parts of any responsible Margherita Peak summit attempt.
Can the Glaciers Be Saved?
Honestly answered: not through local conservation action alone. The Rwenzori’s remaining ice is retreating primarily in response to global climate trends — rising greenhouse gas concentrations driving warming that no amount of park management, however well run, can reverse on its own. Meaningful, long-term change to the trajectory of tropical glacier loss worldwide depends on global climate action: sustained reductions in greenhouse gas emissions at a scale far beyond what any single national park or tourism operator can influence directly.
What local and regional conservation can achieve is narrower but genuinely valuable. The Uganda Wildlife Authority’s protection of Rwenzori Mountains National Park safeguards the surrounding ecosystem, the forests, wildlife and vegetation zones, from the additional pressures of encroachment, poaching and unmanaged tourism, preserving the wider environment within which the glaciers exist even as the ice itself continues to retreat. Ongoing scientific monitoring, including the UNESCO-Project Pressure partnership’s field expeditions and equipment installations, ensures that the Rwenzori’s retreat is documented with increasing precision, building both a valuable scientific record and public awareness. And responsible, well-guided tourism that channels income directly to Bakonzo guides, porters, and communities gives local people a direct economic stake in protecting the broader mountain environment, even as the glaciers themselves lie largely outside anyone’s local control.
Myths and Misconceptions
“The glaciers are already gone.”
Not accurate. As of the most recent field expeditions, glacier ice remains on the Stanley Plateau below Margherita Peak. It is far smaller than a century ago and continuing to shrink, but it has not disappeared.
“The Rwenzori are volcanic.”
Incorrect. Unlike Kilimanjaro, Mount Kenya and the Virunga range, the Rwenzori are a non-volcanic, fault-block mountain range, uplifted along rift faults from ancient Precambrian basement rock roughly two billion years old.
“Glaciers only exist near the poles.”
Incorrect. Glaciers form wherever terrain sits above the local freezing altitude, regardless of latitude. Because temperature falls predictably with altitude, sufficiently high equatorial peaks, the Rwenzori, Kilimanjaro, and Mount Kenya, among them, can and do sustain glaciers.
“One cold winter, or one wet year, can restore the glaciers.”
This is improbable and unsupported by the evidence. Tropical glaciers respond to sustained, long-term climate trends built up over decades, not single seasons. A short period of higher rainfall, such as recent above-average precipitation in the region, may briefly slow the rate of loss, but reversing more than a century of retreat would require a sustained, long-term shift back toward a cooler, snowier climate regime.
Best Time to See the Glaciers on a Margherita Peak Trek
The clearest views of the Stanley Plateau glacier, and the safest conditions for the glacier crossing itself, come during the Rwenzori’s two dry-season windows: mid-December through mid-February, and June through August. Trails are firmer, visibility on the exposed passes is better, and the pre-dawn summit push on Margherita typically encounters clearer skies before the early-afternoon cloud buildup that affects the mountain year-round. The best time to photograph the glacier is in the early morning hours immediately after sunrise, before cloud typically closes in, regardless of season. Trekking outside the two dry windows remains possible and brings a quieter trail and lusher vegetation lower down, but should be planned with the expectation of reduced summit-day visibility and a higher chance of the glacier crossing being affected by fresh snow.
Frequently Asked Questions About Why the Rwenzori Glaciers Are Disappearing?
Primarily because of long-term climate change: rising regional air temperatures, a documented shift toward drier conditions that began in the late nineteenth century, and changes in cloud cover and precipitation patterns that together reduce annual snow accumulation and increase melt.
Yes. As of the most recent field surveys, glacier ice remains on the Stanley Plateau on Mount Stanley, immediately below Margherita Peak.
The summit approach to Margherita Peak crosses the Stanley Plateau glacier, which remains in place, though significantly smaller and thinner than in previous decades.
Most current projections and the sustained multi-decade retreat trend suggest that continued loss is likely, and some scientists working on tropical glaciers describe eventual disappearance within decades as plausible if current climate trends continue. This is a projection based on trend extrapolation, not a fixed date, and should be stated with that caveat.
Estimates vary by study and method, but satellite analysis published in 2024 put the total Rwenzori glacier area at roughly 0.38 km² as of 2021–2022, compared with a reconstructed area of around 6.5 km² in 1906 — a loss of well over 90% of the historical extent.
A 2024 field expedition recorded a 29.5% loss of surface area on the Stanley Plateau glacier alone between 2020 and 2024, indicating that the recent rate of loss is faster than the twentieth-century average.
The scientific literature identifies climate change, which encompasses changes in temperature, precipitation, and cloud cover, as the primary driver. Local factors such as topography and aspect (shaded versus sun-facing slopes) influence exactly where remaining ice persists longest, but do not explain the overall retreat trend.
The first detailed scientific mapping was completed during the Duke of the Abruzzi’s 1906 Italian expedition, which produced the earliest reliable estimate of the range’s total glacier area.
Ongoing monitoring involves the Uganda Wildlife Authority, UNESCO, and independent research groups, including Project Pressure and university-affiliated glaciologists, who use satellite imagery, GPS survey, drone photogrammetry, and ground-penetrating radar.
Yes. Guided glacier travel across the Stanley Plateau remains part of the standard summit-day itinerary for both the Kilembe Trail and Central Circuit routes, using crampons, ice axe and rope under professional guidance.
No formal certification is required, as guides lead the technical sections on rope and provide instruction beforehand, though general fitness and comfort with exposure and cold conditions make the experience considerably more comfortable.
The general route via Elena Hut and the Stanley Plateau remains the same, but the specific line taken across the glacier, and the balance between ice and rock, is adjusted by guides each season as the ice thins and its margins shift.
Because altitude, not latitude, determines whether a mountain is cold enough to sustain permanent ice. The Rwenzori’s highest peaks rise above the equatorial freezing line, which typically sits between 4,500 and 5,100 metres.
All three ranges are losing glacier area, but the Rwenzori has retained a slightly higher proportion of its historical extent, roughly 5.8% remaining as of the early 2020s, compared with 8.6% for Kilimanjaro and 4.2% for Mount Kenya, according to the 2024 Environmental Research: Climate study, likely reflecting the Rwenzori’s wetter, cloudier climate.
Research points to a documented shift toward a drier regional climate across East Africa beginning in the late nineteenth century, which reduced the snowfall available to sustain the glaciers even before the more recent phase of temperature-driven warming took hold.
The rivers rising in the Rwenzori, including the Nyamwamba, are fed primarily by the range’s very high rainfall rather than by glacial melt alone, though the mountain’s overall water balance, including its ice, plays a role in the broader hydrological system.
No single local activity accounts for the retreat. The scientific consensus attributes it to broader regional and global climate change rather than land use around the mountain’s base.
Mid-latitude glaciers respond mainly to a seasonal cycle of summer melt and winter accumulation driven largely by temperature. Tropical glaciers like the Rwenzori’s experience far less seasonal temperature variation and are instead strongly influenced by humidity, cloud cover and precipitation, which govern melt through their effect on solar radiation and surface albedo.
Glaciologists, including Georg Kaser, reconstructed historical extents by comparing the Duke of the Abruzzi’s original 1906 survey maps against later aerial photography and field observations, cross-checking the reconstructions against physical evidence such as moraine positions.
Yes. Repeat photography comparing early twentieth-century expedition photographs with modern images, along with recent drone and satellite imagery from expeditions such as Project Pressure’s 2024 survey, provides a visual record of the retreat alongside the numerical data.
Retreating ice typically exposes bare, freshly scoured bedrock and can increase the likelihood of localised rockfall on steep, recently deglaciated slopes, while meltwater and rainfall continue to feed the alpine lakes and streams in the surrounding valleys.
It is expected to influence habitats adapted to the coldest, highest ground over time, following patterns documented on other tropical mountains, though comprehensive Rwenzori-specific studies quantifying these effects on wildlife are still limited.
For the Bakonzo people, the mountain’s ice holds deep spiritual significance, associated in traditional belief with the deities Kithasamba and Nyabibuya, making its retreat a matter of cultural as well as environmental loss.
Local and regional conservation cannot reverse a trend driven by global climate change, but it can protect the surrounding ecosystem, support rigorous scientific monitoring, and help communities adapt — all valuable, even though they cannot halt the ice loss itself.
Yes, if witnessing this landscape matters to you: the glacier that remains today will very likely look different, and be smaller, in years to come. A well-guided trek today lets you experience genuine equatorial glacier travel, current and accurate information about the mountain’s condition, and a landscape that is still, by any measure, extraordinary.
See Africa’s Equatorial Glaciers While They Remain
One of the World’s Great Natural Wonders is still here to be witnessed, but it will not remain unchanged. A trek to Margherita Peak is more than a summit climb: it is an opportunity to walk across one of Earth’s rarest surviving equatorial glacier systems, and to understand, first-hand, the forces that continue to shape the Mountains of the Moon. Our guides carry not only the route in their heads, but the history, geology and environmental science of this remarkable landscape — sharing it with you at every camp along the way.
There is no better time to see this ice than now, and no better way to see it than with people who have spent their working lives on this mountain. Every detail, from your acclimatisation schedule to your glacier-crossing safety briefing, is already handled. All that is left is your decision.
