The Great Glaciers of Nepal
Nepal's major Himalayan glaciers — Khumbu, Ngozumpa, Langtang and more — where they are and how trekkers can see them.
Nepal is one of the most heavily glaciated countries outside the polar regions. More than three thousand glaciers grind down from its Himalayan crest, storing frozen water that feeds the Koshi, Gandaki and Karnali river systems. This guide maps the country's most significant glaciers and shows how ordinary trekkers can stand beside them.
The short answer
Nepal's best-known major glaciers all lie high in the Himalaya region. In the east, the Khumbu Glacier tumbles from the slopes of Everest and is crossed on the Base Camp trail, while the Ngozumpa Glacier beside the Gokyo lakes is the longest in the country. To the west, the Annapurna Glacier fills the head of the Annapurna Sanctuary, and in the north the Langtang Glacier and the small, intensively studied Yala Glacier sit above the Langtang valley. Far out in Mustang, the Rikha Samba Glacier is one of the most measured glaciers in the whole Himalaya. Most can be seen on foot without any mountaineering.
Glaciers of the Everest region
The Everest, or Khumbu, region holds Nepal's most visited ice. The Khumbu Glacier is the highest glacier on Earth at its source in the Western Cwm, and the Everest Base Camp trail steps directly onto its rubble-strewn surface near Gorak Shep. A valley to the west, the Ngozumpa Glacier flows for some 36 kilometres beneath Cho Oyu, its dark debris-covered tongue and supraglacial ponds visible the whole way up the Gokyo lakes trail. Both lie within Sagarmatha National Park.
Glaciers of central and western Nepal
In the Annapurna massif, the Annapurna Glacier drops from the south face of Annapurna I into the amphitheatre of the Annapurna Sanctuary, the turnaround point of the classic Base Camp trek in the Annapurna region. Deep in Mustang behind the Dhaulagiri wall, the Rikha Samba Glacier has been monitored for decades and is a key reference glacier for measuring Himalayan ice loss.
Glaciers of the Langtang valley
North of Kathmandu, the Langtang Glacier feeds the river that gives the valley its name, while the compact Yala Glacier above Kyanjin Gompa has become an open-air laboratory for glaciologists thanks to its easy access on the Langtang region trek. This valley is the closest big-mountain glacier country to the capital, reached entirely by road and trail with no flights, which makes it the gentlest introduction to Himalayan ice for many first-time visitors.
What a Himalayan glacier really looks like
Visitors often expect a Himalayan glacier to be a sheet of clean white ice. The reality, especially on the larger valley glaciers, is very different. The lower tongues of glaciers like the Ngozumpa and Khumbu are debris-covered: a thick blanket of rock and rubble carried down from the peaks insulates the ice beneath, so the surface looks brown and rocky, pitted with turquoise meltwater ponds and laced with crevasses. Higher up, the ice is cleaner and broken into seracs and icefalls. Understanding this helps set expectations — and explains why so many glaciers are best appreciated from a viewpoint above, such as Gokyo Ri or Kala Patthar, rather than from their dull-looking snouts.
A shrinking frozen reserve
Nepal's glaciers are not just scenery; they are a vast frozen reservoir that feeds the rivers millions depend on. They are also retreating fast. The small, much-studied Yala Glacier may disappear within a few decades, and warming has formed and enlarged dangerous glacial lakes such as Imja, raising the risk of outburst floods downstream. Visiting these glaciers responsibly — and understanding their fragility — is part of travelling thoughtfully in the high Himalaya.
Seeing them responsibly
Glaciers are dangerous places — crevasses, rockfall and unstable moraine are real hazards, so admire them from the marked trails rather than wandering onto the ice. These are also high-altitude destinations, so plan around the clear post-monsoon and spring windows in our best time to visit Nepal guide, and read the Nepal trekking guide for permits and acclimatisation before you go. Tap any glacier below for its length, location and the trek that reaches it.

Frequently asked questions
How many glaciers does Nepal have?+
Nepal has more than three thousand glaciers spread across its Himalayan ranges, covering several thousand square kilometres. Most are small valley and cirque glaciers high above the treeline, but a handful — including the Khumbu and Ngozumpa — are large debris-covered glaciers that feed the country's major rivers.
What is the longest glacier in Nepal?+
The Ngozumpa Glacier in the Everest region is generally regarded as the longest glacier in Nepal, stretching roughly 36 kilometres down from Cho Oyu beside the Gokyo valley. The neighbouring Khumbu Glacier is more famous but shorter.
Can tourists see Nepal's glaciers without climbing?+
Yes. Several major glaciers are crossed or skirted on popular treks. The Everest Base Camp trail walks onto the Khumbu Glacier, the Gokyo trek runs alongside the Ngozumpa, and the Annapurna Base Camp and Langtang treks bring you within sight of large glaciers, all without any technical climbing.
Are Nepal's glaciers shrinking?+
Yes. Nepal's Himalayan glaciers are retreating and thinning as the climate warms, and many are losing mass rapidly. This has formed and enlarged glacial lakes such as Imja, raising the risk of glacial lake outburst floods and threatening the long-term water supply of millions downstream.
