Licancabur
Rising almost perfectly above the high desert on the border of Chile and Bolivia, Licancabur is one of the most recognizable volcanoes of the Central Andes. Its steep, symmetrical cone towers above salt flats, turquoise lagoons, barren volcanic plateaus, and the extraordinarily dry landscapes surrounding the Atacama Desert.
Licancabur is remarkable for far more than its appearance. A small lake occupies its summit crater at nearly 6,000 meters above sea level, making it one of the world’s highest crater lakes. Archaeological structures near the summit reveal that Indigenous people climbed the mountain centuries before modern mountaineers arrived, while scientists have studied the extreme environment of Licancabur as an earthly comparison for conditions that may once have existed on Mars.
Depending on the source, Licancabur’s elevation is given slightly differently. Peakbagger lists the summit at 5,926.2 meters (19,443 feet), while the Smithsonian Institution’s Global Volcanism Program uses 5,916 meters (19,409 feet). Both figures describe the same enormous volcanic cone dominating the Chile–Bolivia frontier.

📍 Where Is Licancabur?
Licancabur stands directly on the international boundary between Bolivia and Chile, where Bolivia’s Potosí Department meets Chile’s Antofagasta Region.
The volcano rises east of San Pedro de Atacama, one of northern Chile’s best-known desert towns. From San Pedro and many surrounding viewpoints, Licancabur forms an unmistakable landmark on the eastern horizon.
On its Bolivian side, the mountain rises above the spectacular Laguna Verde, a high-altitude lake famous for its vivid colors and barren volcanic surroundings. This landscape belongs to the far southwestern corner of Bolivia, an area characterized by salt flats, volcanoes, geothermal fields, flamingo-filled lagoons, and some of the harshest high-altitude environments in South America.
Licancabur belongs to the broad Central Andes, where volcanic mountains extend across southern Peru, Bolivia, northern Chile, and northwestern Argentina. This is also part of the greater Puna and Altiplano highland system described in our Map of the Andes Mountain Range.
📏 How High Is Licancabur?
Licancabur’s exact published elevation varies between major geographic and volcanological databases.
Peakbagger lists the summit at 5,926.2 meters (19,442.9 feet). The Smithsonian Global Volcanism Program lists an elevation of 5,916 meters (19,409 feet).
A difference of around ten meters is not especially unusual for remote high Andean summits. Elevation figures can differ because of the maps, surveys, satellite data, and summit coordinates used by different organizations.
For the Mountain Field Guide’s topographic statistics, the Peakbagger figure of 5,926.2 meters is useful because it is accompanied by prominence and parent-peak data. When discussing Licancabur as a volcano, readers will commonly encounter the Smithsonian’s 5,916-meter figure.
Either way, Licancabur rises well above 19,000 feet and presents a genuinely extreme high-altitude environment.
🧭 Nearest Higher Neighbor
Licancabur’s nearest higher parent is Sairecabur, another enormous stratovolcano on the Chile–Bolivia border.
Peakbagger lists Sairecabur as Licancabur’s line parent. Sairecabur reaches approximately 5,971 meters (19,590 feet), making it only slightly higher than Licancabur.
The relationship is especially interesting because the two volcanoes occupy the same spectacular high-desert volcanic landscape. From a distance, both rise dramatically above the elevated plateau, although Licancabur’s remarkably symmetrical cone often makes it the more visually dominant landmark.
Licancabur has approximately 1,436 meters (4,711 feet) of topographic prominence, giving it considerable independence despite the presence of higher Andean volcanoes nearby.
🌋 A Classic Andean Stratovolcano
Few volcanoes have a profile as immediately recognizable as Licancabur.
Its steep-sided cone rises abruptly above a much broader volcanic landscape, producing the classic shape associated with a stratovolcano. The Smithsonian Global Volcanism Program classifies Licancabur as a composite stratovolcano within the Central Andean Volcanic Arc.
This volcanic belt exists because the oceanic Nazca Plate is being forced beneath the South American Plate along the western margin of the continent.
As the descending plate moves deeper into the mantle, geological processes contribute to magma generation beneath the Andes. Over millions of years, repeated volcanic activity has constructed an immense chain of volcanoes extending across this part of South America.
Licancabur is one of countless volcanic features produced by this tectonic environment, but its unusually symmetrical form makes it one of the most striking.
🪨 Geology of Licancabur
Licancabur is built primarily from andesitic, basaltic-andesitic, and dacitic volcanic rocks.
The cone rises above an older volcanic foundation composed partly of ignimbrites and lava domes. The surrounding landscape preserves evidence of multiple generations of enormous volcanic events that long predate the modern Licancabur cone.
Young-looking lava flows descend from Licancabur’s upper slopes. Some flows have clearly preserved levees along their margins, while blocky lava extends for several kilometers from the summit region.
The volcano’s appearance suggests relatively youthful geological construction. Much of the present cone developed during the geologically recent past, although establishing a precise eruption chronology has proven difficult.
Immediately southeast of Licancabur is Juriques, an older neighboring volcano with a dramatically different summit. Rather than Licancabur’s pointed cone and smaller summit crater, Juriques possesses a large eroded crater approximately 1.5 kilometers across.
Seen together, Licancabur and Juriques offer an excellent visual example of how volcanic mountains change as erosion and time reshape them.
💥 Is Licancabur an Active Volcano?
Licancabur is a geologically young volcano, but there is no well-established historical eruption record.
The Smithsonian Global Volcanism Program lists its last known eruption as unknown, with credible geological evidence of relatively young activity but no confirmed eruption chronology comparable with actively monitored volcanoes such as nearby Lascar.
This distinction matters.
Calling Licancabur simply an “active volcano” can imply that recent eruptions have been documented, while calling it extinct would go too far in the opposite direction. The most accurate description is that Licancabur is a young stratovolcano whose precise eruptive history remains incompletely known.
Its youthful lava flows nevertheless demonstrate that volcanic activity has played a major role in shaping the mountain.
💧 Licancabur’s Summit Crater Lake
At the top of Licancabur lies its most unusual natural feature: a small lake occupying the summit crater.
The crater itself is approximately 400 meters wide, while the lake occupies only a portion of its floor. Despite its modest size, its extraordinary elevation makes it scientifically important.
Conditions here are severe. Atmospheric pressure is dramatically lower than at sea level, temperatures are extremely cold, oxygen availability is reduced, and ultraviolet radiation is intense.
Yet the lake does not remain completely frozen from top to bottom throughout the year. Researchers have found that liquid water can persist beneath its ice.
This combination of extreme altitude, water, intense solar radiation, cold temperatures, and thin atmosphere transformed Licancabur into a natural laboratory.
🔴 Why NASA Studied Licancabur
Licancabur has attracted considerable interest from astrobiologists, including scientists associated with NASA’s Ames Research Center.
Researchers have used the volcano and its lakes as terrestrial analog environments for ancient Mars.
Mars today is cold, dry, and exposed to intense radiation, but geological evidence indicates that liquid water once existed on its surface. Ancient Martian lakes may therefore have experienced environmental conditions with certain similarities to high, cold, intensely irradiated lakes in the Andes.
Licancabur provides researchers with an opportunity to investigate how life survives near environmental limits on Earth.
Microorganisms capable of tolerating cold, ultraviolet exposure, low atmospheric pressure, and nutrient-poor environments can help scientists understand what forms of life might potentially survive under similarly extreme conditions elsewhere.
This does not mean Licancabur is identical to Mars. Instead, it is an accessible natural laboratory where scientists can investigate biological adaptation under a combination of unusually difficult conditions.
🏺 A Sacred Mountain
Licancabur was important to people long before scientists became interested in its crater lake.
The mountain occupies a culturally significant landscape associated particularly with the Lickanantay, or Atacameño, people of the Atacama region. Mountains, volcanoes, water sources, and other natural features have long held deep spiritual meaning within Andean cultures.
Licancabur’s name is commonly associated with the Indigenous Kunza language and is frequently interpreted as meaning something similar to “mountain of the people” or “mountain of the country.”
Its extraordinary shape, dominance over the surrounding landscape, and relationship with nearby water sources would have made it impossible to ignore.
The mountain continued to hold ceremonial significance as the Inca Empire expanded into the southern Andes.
🏛️ Archaeology on Licancabur
One of the most fascinating facts about Licancabur is that archaeological structures exist at extraordinary elevations near its summit.
Researchers have documented stone constructions, ceremonial areas, pottery, wood, and other evidence of pre-Columbian activity. Structures have been found both near the crater and along approaches to the mountain.
This evidence fundamentally changes the way Licancabur’s climbing history should be described.
Older mountaineering accounts sometimes identify a 19th-century climber as completing the “first ascent.” Archaeological remains demonstrate that this cannot represent the true first ascent of the mountain. Indigenous climbers were reaching Licancabur many centuries earlier.
A substantial archaeological complex known as Tambo de Licancabur also lies lower on the mountain. More than a hundred structures have been documented in the broader complex, suggesting that it could accommodate a considerable number of people.
The site may have supported ceremonies connected with the mountain, served travelers moving through the region, or fulfilled multiple roles within the broader Inca and local landscape.
🥾 Pre-Columbian High-Altitude Mountaineering
Licancabur belongs to an extraordinary collection of Andean peaks that preserve evidence of high-altitude climbing before the modern era of mountaineering.
People climbed volcanoes exceeding 5,000 and even 6,000 meters during pre-Columbian times, often for religious or ceremonial purposes. Trails, shelters, platforms, offerings, firewood, pottery, and other artifacts have been discovered on numerous Andean summits.
This makes the Andes unique in the history of human exploration at extreme altitude.
Modern European mountaineering is usually traced through increasingly difficult Alpine ascents beginning centuries later, but Indigenous Andean peoples had already developed the ability to travel and work at elevations where oxygen levels create major physiological challenges.
Licancabur is therefore not merely a climbing destination. It is an important site in the much longer history of humans interacting with very high mountains.
🥾 Climbing Licancabur
Although Licancabur’s symmetrical slopes may appear straightforward from a distance, climbing to almost 6,000 meters is a serious undertaking.
The greatest difficulty is generally not technical rock climbing. It is the combination of extreme altitude, loose volcanic terrain, cold, wind, intense sunlight, isolation, and a large vertical ascent.
At nearly 5,930 meters, atmospheric oxygen pressure is dramatically lower than at sea level. Climbers who ascend too quickly can develop acute mountain sickness, and severe altitude illness can become life-threatening.
Proper acclimatization is therefore essential.
The border location introduces another consideration. Access rules, permitted approaches, local community requirements, protected-area regulations, and international boundary restrictions can change. Anyone considering an ascent should verify current conditions with appropriate local authorities and experienced guides rather than relying on older route descriptions.
The mountain’s apparently simple cone should never be mistaken for an easy hike.
🏜️ The Atacama Desert Landscape
Licancabur rises beside one of the most extraordinary environments on Earth: the Atacama Desert.
Parts of the Atacama receive remarkably little precipitation, and some landscapes appear almost devoid of vegetation. Salt crusts, volcanic rocks, gravel plains, dunes, dry valleys, and enormous volcanoes dominate the scenery.
The contrast between the low desert and the high Andes is especially dramatic around San Pedro de Atacama.
To the west of Licancabur lies the Salar de Atacama basin. To the east and southeast, the high plateau extends into Bolivia, where colorful lagoons occupy closed drainage basins among volcanoes.
This landscape belongs to the broader Puna de Atacama, one of the driest and highest portions of the Andes.
For a broader view of how these landscapes fit together, see our Map of the Andes Mountain Range.
🌊 Laguna Verde
On the Bolivian side of Licancabur lies Laguna Verde, one of the most photographed high-altitude lakes in the region.
Its position directly beneath the volcano creates a remarkable landscape: a pale green or turquoise lake surrounded by barren ground with Licancabur’s near-perfect cone rising behind it.
The lake lies in the extreme southwestern corner of Bolivia, close to several other volcanic peaks.
Laguna Verde and the surrounding high desert reinforce just how unusual Licancabur’s environment is. Water exists beside vast salt flats and deserts, wetlands support wildlife at tremendous elevation, and volcanic mountains rise thousands of feet above the plateau.
☀️ Climate and Weather
Licancabur experiences a harsh high-altitude desert climate.
Humidity is generally low, skies can be exceptionally clear, and solar radiation is extremely strong. Yet conditions high on the volcano are far colder than those experienced in the desert valleys below.
Temperatures can change dramatically between day and night. Strong winds are common in the high Andes, and snow can fall despite the extreme dryness of the surrounding region.
During the Southern Hemisphere summer, moisture associated with the Altiplano wet season, sometimes called the Bolivian winter, can bring thunderstorms, clouds, rain, and high-elevation snow to parts of the Central Andes.
The combination of thin atmosphere and exceptionally clear air also increases exposure to ultraviolet radiation.
For high-altitude travelers, sun protection can therefore be important even when air temperatures feel cold.
🌿 Flora and Fauna
Licancabur’s upper cone can appear almost lifeless, but the broader high-Andean and Atacama environment supports a surprising variety of organisms adapted to severe conditions.
Vegetation is sparse and strongly controlled by elevation and access to moisture. Lower and more favorable areas can support tola shrubs, coirón grasses, llareta cushion plants, rica-rica, pingo-pingo, and other plants characteristic of the high Atacama and puna.
Many grow close to the ground, reduce leaf area, or form dense cushions that help conserve heat and moisture while resisting powerful winds.
Near wetlands and high-altitude water sources, vegetation can become considerably denser.
Wildlife of the greater region includes vicuñas, which are exceptionally well adapted to high elevations and low oxygen levels. Their dense coats provide protection against severe nighttime temperatures.
Vizcachas inhabit rocky terrain, while the culpeo, or Andean fox, ranges through portions of the highlands. Pumas also occur across the wider Andean landscape, although encounters are uncommon.
Birdlife can be surprisingly rich around lagoons and wetlands.
The broader Atacama highlands support Andean flamingos, James’s flamingos, Chilean flamingos, Andean condors, puna rheas, and numerous other specialized birds.
The contrast between the apparently barren volcanic slopes and the wildlife concentrated around wetlands is one of the defining ecological patterns of the Central Andes.
🦩 Flamingos of the High Andes
Flamingos seem almost impossibly delicate against the harsh landscape surrounding Licancabur, yet the high-altitude wetlands of the Central Andes provide habitat for three South American species.
The Andean flamingo, James’s flamingo, and Chilean flamingo occur in the wider region.
These birds depend on saline lakes and shallow wetlands where specialized food resources support their populations. Their bright plumage creates a dramatic contrast with the browns, reds, whites, and volcanic blacks of the desert landscape.
Protecting these aquatic habitats is especially important because water is scarce in the Atacama, and seemingly small environmental changes can have significant ecological effects.
🛡️ Protected Landscapes Around Licancabur
Much of the country surrounding Licancabur is recognized for its exceptional natural and cultural value.
On the Chilean side, important landscapes surrounding San Pedro de Atacama are protected within or associated with Los Flamencos National Reserve. The reserve protects several distinct sectors containing salt flats, wetlands, high-altitude lagoons, desert ecosystems, archaeological sites, and wildlife habitat.
On the Bolivian side, the landscapes south and east of Licancabur connect with the extraordinary protected environment of the Eduardo Avaroa Andean Fauna National Reserve.
Together, these landscapes protect some of the most visually striking high-desert environments in South America.
They also demonstrate that an apparently empty desert can possess considerable biological diversity and cultural significance.
🔬 An Extreme Environment for Science
Few mountains bring geology, archaeology, biology, and planetary science together quite like Licancabur.
Volcanologists study the construction and evolution of the stratovolcano. Archaeologists investigate structures left by people who climbed into an environment where oxygen is scarce and temperatures can be brutal. Ecologists study organisms adapted to high elevation and aridity.
Astrobiologists go one step further, asking what these adaptations might tell us about the possibility of life beyond Earth.
The summit crater lake is particularly valuable because several environmental stresses occur simultaneously: high ultraviolet radiation, low atmospheric pressure, freezing conditions, reduced oxygen, and limited nutrients.
Understanding how microbial ecosystems respond to those stresses helps researchers investigate the outer environmental limits of life as we know it.
🏔️ Licancabur and Sairecabur
The relationship between Licancabur and its nearest higher neighbor, Sairecabur, helps place the mountain in its broader geographic setting.
Sairecabur rises north of Licancabur and reaches approximately 5,971 meters. It is itself part of a larger volcanic complex and occupies the same Chile–Bolivia frontier.
Although Sairecabur is slightly higher, Licancabur is generally more recognizable because of its exceptionally symmetrical cone and prominent position above San Pedro de Atacama.
Together, the mountains help define this portion of the Central Andes, where enormous volcanoes rise directly from one of the driest highland environments on Earth.

🌄 Why Licancabur Is Remarkable
Licancabur brings together nearly every quality that makes the Central Andes extraordinary.
It is a towering stratovolcano born from plate tectonics. It rises beside the Atacama, one of Earth’s driest deserts. Its summit contains a lake in an environment close to the limits of biological survival. Its slopes preserve evidence of ancient human journeys into extreme altitude, while its landscape remains culturally significant to Indigenous communities.
Modern scientists have even used Licancabur to ask questions about another planet.
Few mountains connect such different stories.
From the volcanic history of the Andes to pre-Columbian mountaineering, high-altitude wildlife, astrobiology, and the spectacular desert landscapes of Chile and Bolivia, Licancabur is far more than a beautiful cone on the horizon.
It is one of the defining mountains of the Puna de Atacama — a place where geology, culture, life, and extreme environment converge nearly six kilometers above sea level.
