Top 10 Glaciers in Colombia
Colombia is home to some of the most endangered glaciers on Earth. The country's six glaciated mountain massifs — the Sierra Nevada de Santa Marta, Nevado del Cocuy, Nevado del Huila, Nevado del Ruiz, Nevado de Santa Isabel, and Nevado del Tolima — together constitute fewer than 50 square kilometres of glacier area, a figure that represents a dramatic reduction from the several hundred square kilometres documented in the early 20th century. At current rates of retreat, several of these glaciers may disappear entirely within decades, making Colombia a frontline case study for the global crisis of tropical glacier loss.
The combination of rising temperatures, reduced precipitation in some regions, and the particular sensitivity of tropical glaciers — which receive ablation year-round without a seasonal cold period to arrest melting — makes the Colombian glacier situation acute. International scientific attention and increasing national awareness have focused on these ice bodies as both ecological and cultural heritage under threat.

1. Sierra Nevada del Cocuy Glacier, Boyaca Department
The Cocuy massif in the Cordillera Oriental hosts the largest glacier complex in Colombia, covering roughly 16 square kilometres as of recent measurements — though this figure declines with each updated survey. The massif's 25 peaks rise above 5,000 metres, with the highest, Ritacuba Blanco, reaching 5,330 metres. The glaciers here are accessible from the town of El Cocuy via hikes of several days, and the protected area of the Sierra Nevada del Cocuy National Park surrounds the massif. The park was partially closed to visitors for several years after 2017 due to conflict between tourism impact and the cultural significance of the glaciers for the indigenous U'wa people.
2. Nevado del Ruiz Glacier, Tolima-Caldas Border
Nevado del Ruiz (5,321 m) is one of the most notorious volcanoes in South America because of the 1985 eruption that generated lahars — volcanic mudflows — that destroyed the town of Armero and killed more than 23,000 people. The lahars were generated when the eruption melted a significant portion of the glacier cap in minutes, releasing enormous volumes of water that mixed with volcanic ash and debris. The glacier that remained after 1985 has continued to retreat, and Ruiz is still volcanically active, making glacier monitoring here a matter of disaster risk reduction as much as scientific interest.
3. Nevado del Huila Glacier, Huila Department
Nevado del Huila (5,364 m) is the highest volcano in Colombia and hosts glaciers on its central and north summits. Like Ruiz, Huila is volcanically active, and eruptions in 2007 and 2008 generated lahars that displaced indigenous Nasa communities in the upper Paez River valley. The glacier on Huila is one of the more substantial remaining Colombian glacier bodies and is monitored by IDEAM — Colombia's national meteorological and environmental institute — as part of the national glacier monitoring programme.
4. Nevado de Santa Isabel Glacier, Risaralda Department
Santa Isabel (4,965 m) is the lowest of Colombia's volcanic peaks and hosts a small but scientifically valuable glacier. It is located within Los Nevados National Natural Park and is accessible by road to a high elevation before a short hike to the glacier margin. The Santa Isabel glacier has been retreating rapidly and is often cited as the Colombian glacier closest to complete disappearance, with some studies suggesting it could be ice-free within 20 to 30 years. Its accessibility and symbolic status have made it the focus of considerable public education efforts about Colombian glacier loss.
5. Nevado del Tolima Glacier, Tolima Department
Nevado del Tolima (5,215 m) is a symmetrical volcanic cone visible from the city of Ibague on clear days and hosts a small glacier on its upper slopes. The peak is a popular mountaineering objective and the approach, through the coffee-growing foothills and paramo ecosystems of the central Andes, is one of the most ecologically diverse in Colombia. The glacier cap has shrunk considerably and now occupies only the uppermost part of the summit cone. The Los Nevados Park, which encompasses Tolima, Ruiz, and Santa Isabel, is one of Colombia's most important protected areas.
6. Pico Cristobal Colon Glacier, Sierra Nevada de Santa Marta
The Sierra Nevada de Santa Marta is entirely distinct from the Andean volcanic chain — it is an isolated granitic massif rising from coastal lowlands near the Caribbean coast to Pico Cristobal Colon and Pico Simon Bolivar, both around 5,775 metres, making them Colombia's highest peaks by some accounts. The glaciers on the massif are extremely small by global standards but of enormous scientific interest because of their isolation from the Andes and their position at such low latitude and modest altitude. They are retreating rapidly and are expected to disappear within the coming decades.
7. Pico Simon Bolivar Glacier, Sierra Nevada de Santa Marta
Adjacent to Cristobal Colon, Pico Simon Bolivar shares the highest elevation in the Sierra Nevada de Santa Marta. The glaciers on both peaks are accessible only through indigenous Kogi and Arhuaco territory, and permits and guides from local communities are required for any approach. This indigenous territorial control has limited scientific access but also provided a degree of protection from unregulated tourism impact. The ice is sacred to the Kogi people, for whom the glaciers are a fundamental part of cosmological understanding.
8. Ritacuba Blanco Ice, Cocuy Massif
Ritacuba Blanco, the highest summit of the Cocuy massif at 5,330 metres, is the most frequently climbed glaciated peak in Colombia and a classic mountaineering objective from Bogota and Bucaramanga. The glacier on the summit and upper ridges provides the ice climbing required for the normal route and has been the site of substantial mountaineering accidents over the years, many related to underestimation of altitude effects and technical ice conditions. The glacier here is relatively well-documented because of the route's popularity.
9. Los Nevados Central Plateau Glaciers, Central Andes
Between the summits of Ruiz, Santa Isabel, and Tolima in Los Nevados National Park, a series of smaller glaciers and permanent snowfields occupy the high plateau and connecting ridges above 4,800 metres. These include the glaciers on the flanks of El Cisne volcano and small ice patches on several unnamed ridges. While individually small, they collectively represent an important part of the headwater system for rivers draining to the Cauca and Magdalena valleys and are monitored as part of the park's hydrological assessment.
10. Diamante Glacier, Cocuy Massif
Diamante is one of the named glaciers within the Cocuy massif system and occupies a south-facing cirque that receives less solar radiation than the east and west-facing ice bodies. This aspect has moderated its retreat somewhat relative to other glaciers in the massif. Photographs from the 1950s and 1970s show a much more extensive ice body, and the trimlines left by the glacier's former extent are clearly visible on the surrounding rock walls, providing an unmistakable visual record of a century of retreat.
