Tilicho Lake, Nepal: Location, Altitude, Facts & Travel Guide

Tilicho Lake is one of the most well known high altitude lakes in Nepal, but its fame is not only about how high it lies. Located in the Manang district at 4,919 metres above sea level, it lies beyond the main villages of the Annapurna region and has become a popular side trip for trekkers on the Annapurna Circuit.

Its location raises an obvious question about what is a lake doing at nearly 5,000 metres? The answer involves the geography of the Himalayas, glaciers, and the unusual landscape around the Annapurna range. The area also has a history and religious importance that goes beyond trekking.

Whether you are researching the lake before a trek or just trying to understand what makes Tilicho Lake so well known, there is more to it than its famous altitude. And one question is particularly interesting: is Tilicho Lake really one of the highest lakes in the world? 

Where is Tilicho Lake Located?

Tilicho Lake is located in Manang District of Gandaki Province, Nepal, within the Annapurna Conservation Area. It lies on the northern side of the Annapurna massif, in a high mountain basin below Tilicho Peak. The lake is at approximately 28°41′30″N, 83°51′10″E.

It is reached from the Manang Valley through Khangsar and Tilicho Base Camp. The route to the lake branches away from the main Annapurna Circuit trail near Manang before continuing towards the high alpine basin. Manang and Khangsar are the main settlements associated with the Tilicho Lake route.

Tilicho Lake Name and Religious Significance

Tilicho Lake is also known as Tilicho Tal, a name commonly used in Nepal for the lake. The exact origin and literal meaning of “Tilicho” are not firmly established in reliable historical or linguistic records. Several explanations appear in travel sources, but they should not be presented as fact without stronger evidence.

The lake has another important name in Hindu tradition: Kak Bhusundi Lake, or Kak Bhusundi Sarovar. Hindu tradition identifies Tilicho with the sacred lake associated with the sage Kak Bhusundi in the Ramayana. According to the tradition, Kak Bhusundi, who is said to have taken the form of a crow, narrated the story of the Ramayana to Garuda, the divine bird and vehicle of Lord Vishnu.

This identification is a matter of religious belief rather than a geographically or historically proven connection. Even so, the association has given Tilicho Lake an important place in Hindu religious tradition and adds a cultural dimension to a lake otherwise best known for its remarkable Himalayan location.

How High is Tilicho Lake?

Tilicho Lake lies at 4,919 metres (16,138 feet) above sea level. At this elevation, it is well above the tree line and within the high alpine zone of the Annapurna Himalayas.

The elevation of Tilicho Lake is particularly notable because it is a large freshwater lake at such a high altitude. It covers approximately 4.8 square kilometres, making the combination of its size and elevation more significant than the altitude figure alone.

You may also see the Tilicho Lake altitude given as 4,949 metres in some references. The commonly accepted figure is 4,919 metres, and this is the elevation that is used most when referring to the height of Tilicho Lake.

Is Tilicho Lake the Highest Lake in the World?

No. Tilicho Lake is not the highest lake in the world. At 4,919 metres above sea level, it is one of the highest large lakes on Earth, but smaller lakes at much greater elevations are known. The crater lake on Ojos del Salado, on the Chile Argentina border, is generally regarded as the highest known lake, at around 6,390 metres.

The old description of Tilicho as the world’s highest lake came from its exceptional elevation and its comparatively large size. That wording is still found in some Nepal publications, but it is not accurate as a worldwide record. A more precise description is one of the highest large high altitude lakes in the world.

There is an interesting distinction within Nepal as well. Kajin Sara Lake, in Manang District, has been reported at elevations above Tilicho, including figures around 5,000 metres. However, the exact elevation remains subject to verification, so it is better not to present Kajin Sara as an officially established world or national record.

Tilicho Lake: Size, Depth and Physical Features

Tilicho Lake is approximately 4 kilometres long and up to 1.2 kilometres wide, with a commonly cited surface area of about 4.8 square kilometres. Measurements of the lake have varied, however, particularly because its water level and mapped shoreline can change. A hydrological study recorded a water surface of about 3.54 square kilometres at the time of its survey.

The average depth of Tilicho Lake is about 85 metres. It is a freshwater lake of glacial origin, fed by snow and ice melt from the surrounding mountains. The basin is enclosed by rocky slopes and glacial deposits, with very little vegetation around the shoreline because of the elevation.

The lake lies in a cold, dry high Himalayan environment north of the main Annapurna range. Its water surface freezes during winter, while snow, ice and exposed rock dominate much of the surrounding landscape. The combination of its size, depth, glacial origin and elevation makes it an unusual lake even among Nepal's many high altitude lakes. 

How Was Tilicho Lake Formed?

Tilicho Lake is believed to have formed after a massive rockslide from the Khansar Kan ridge blocked part of the Upper Marsyangdi Valley. The fallen rock and debris created a natural dam, leaving a large depression where water could accumulate.

Over time, this basin filled with meltwater from snow, ice and glaciers around Tilicho Peak and the Annapurna massif. The lake is not fed by a major river; its water comes mainly from glacial melt and snow, with avalanches also contributing water and debris to the basin.

The result is a lake formed by two major natural processes: a large rockslide created the basin, while glacial meltwater filled it. This explains why its origin is different from lakes formed solely by direct glacial erosion. 

Geography of Tilicho Lake

Tilicho Lake is part of the Manang Himalaya, in the upper Marsyangdi basin of central Nepal. The area lies on the northern side of the Annapurna range, where the mountain system creates a strong climatic divide. Manang falls within the rain shadow of the Annapurna and Dhaulagiri ranges, which gives the region a much drier character than the southern slopes of the Himalayas.

The wider landscape is made up of high ridges, deep valleys and mountain passes connecting Manang with neighbouring Himalayan regions. To the west, the terrain leads toward the Kali Gandaki valley, while the Marsyangdi drainage extends eastward through Manang. Tilicho Peak, Gangapurna and Annapurna III are among the major peaks associated with the surrounding mountain landscape.

Another important geographical feature is the change in elevation across a relatively short distance. The Marsyangdi valley rises from subtropical areas toward the high Himalayan environment around Manang and Tilicho. This creates major differences in climate, vegetation and landform within the same river basin, making the region particularly important for trekking in Nepal and for routes such as the Annapurna Circuit Trek and Nar Phu Valley Trek.

Climate and Weather at Tilicho Lake

Tilicho Lake has a cold, dry alpine climate. The area is protected from much of the summer monsoon by the Annapurna range, so rainfall is considerably lower here than on the southern side of the mountains. At this elevation, however, cold conditions remain possible even outside winter, particularly at night and during periods of strong wind.

Spring brings a gradual reduction in snow and clearer weather, although snow can remain around the higher parts of the route early in the season. Summer coincides with the monsoon, but the Manang side of the mountains receives less rainfall because of the rain shadow. Cloud, rain and unstable conditions can still affect the way to the lake.

Autumn, especially October and November, is the best time for the Tilicho Lake trek, with dry weather and good mountain visibility. Winter brings a lot of cold, with snowfall and freezing conditions becoming more common at high elevations. The lake can freeze during the colder months, depending on the severity and duration of winter conditions.

Why is Tilicho Lake Famous?

Tilicho Lake is famous for its high elevation, size and striking location in the Annapurna Himalayas. At 4,919 metres, it is one of the highest large lakes in Nepal and has become one of the best known natural landmarks in the Manang region.

It is also a well known destination on the Annapurna Circuit Trek, with a separate route leading from the Manang area to the lake. The old claim that Tilicho was the highest lake in the world added to its reputation, although that is no longer an accurate description.

Its Hindu religious significance is another part of its identity. The lake is traditionally associated with Kak Bhusundi Lake from the Ramayana. Its unusual formation, high altitude and place in Nepal's Himalayan landscape give it importance beyond trekking.

How to Reach Tilicho Lake

Besisahar is the usual starting point for the Manang side of the journey. Jeeps operate along the Marsyangdi Valley, and the road reaches Manang village. Khangsar is the main access point for Tilicho Lake, with Shree Kharka and Tilicho Base Camp along the route.

There is no road to the lake itself. Tilicho Base Camp is the last place with basic overnight accommodation, and the lake requires a hike from there. The distance is short, but the altitude and steep ground make this part of the journey physically challenging.

Kathmandu and Pokhara are both connected to Besisahar by road. Visitors doing the Annapurna Circuit Trek can include Tilicho Lake around Manang, while a separate Tilicho trek itinerary can be arranged without completing the entire circuit. 

Ecosystem and Wildlife Around Tilicho Lake

The ecosystem around Tilicho Lake is part of the Annapurna Conservation Area and consists mainly of alpine land, rocky slopes, grasslands and sparse vegetation. The high elevation limits tree growth, while small grasses, shrubs and other alpine plants survive around the lake and nearby mountain slopes.

The wider Manang region supports Himalayan marmots, blue sheep, Himalayan tahr and various high altitude birds, although wildlife is limited around the lake itself because of the extreme elevation. The wider Manang region is also home to snow leopards, although they are rarely seen around the lake itself.

The lake forms part of the wider high altitude ecosystem of Nepal, where plants and animals have adapted to harsh mountain conditions. Its surroundings are more important for alpine biodiversity than for aquatic wildlife, with the broader Annapurna landscape providing habitat for a much wider range of species.

Tilicho Lake and Tilicho Peak

Tilicho Peak is a 7,134 metre mountain in the Damodar Himal, on the northern side of the Annapurna massif. Tilicho Lake lies below the mountain, in a high basin surrounded by the peaks and glaciers of the Manang Himalaya. The name of the lake is closely associated with Tilicho Peak, which is one of the most prominent geographical features in the area.

The mountain was first climbed in 1978 by a French expedition led by Emmanuel Schmutz. Tilicho Peak is a mountaineering peak rather than a trekking destination, with climbing routes requiring considerably more technical experience than the approach to Tilicho Lake.

The close location of the 7,134 metre Tilicho Peak and 4,919 metre Tilicho Lake helps explain the landscape around the lake. Snow and ice from the surrounding mountains contribute meltwater to the high mountain basin, while the steep slopes and exposed rock give the area its characteristic Himalayan setting.

Tilicho Lake Compared With Other High Altitude Lakes

Tilicho Lake is often compared with other high altitude lakes in Nepal, particularly Kajin Sara, Gokyo Lakes, Tsho Rolpa and Gosaikunda. The comparison is useful because their elevations, size and geographical settings are different. Tilicho is not Nepal’s highest lake by elevation, but its 4,919 metre altitude and large water surface give it a distinct position among the country’s alpine lakes.

Kajin Sara has been reported at a higher elevation than Tilicho Lake, but its exact altitude has not been firmly established through authoritative surveying. The Gokyo Lakes reach similar elevations, while Tsho Rolpa and Gosaikunda are lower. Tilicho's notable feature is its combination of elevation, depth and size, rather than holding the highest lake record by altitude alone.

Final Thoughts

At 4,919 metres, Tilicho Lake is a remarkable part of the Manang landscape, but its altitude is only one reason people know it. The lake's unusual size, glacial setting, geological history, and connection with Hindu tradition make it far more interesting than a number on a map. It may not be the highest lake in the world, but Tilicho Lake remains one of Nepal's best known high altitude lakes and a distinctive feature of the Annapurna region.
