Sierra Nevada del Cocuy

The Sierra Nevada del Cocuy is a compact but spectacular glaciated range in the Eastern Andes of Colombia, part of El Cocuy National Natural Park in Boyacá. Its cluster of snow peaks, the highest around 5,330 metres, rise above frailejón-studded páramo and turquoise glacial lakes, forming one of the most beautiful high-mountain landscapes in the country.

The park is best known for its day hikes to the glaciers and lakes rather than a single set-piece trek, with three main routes climbing from valley trailheads to viewpoints on the ice edge at around 4,600 to 5,000 metres. Each is a strenuous day of six to nine hours return at high altitude. A longer multi-day traverse of the range, once popular, has at times been restricted by the park and the Indigenous U'wa people who hold the mountains sacred.

Difficulty is challenging. The hikes themselves are non-technical, but the thin air, steep climbs and cold, exposed high ground make them demanding, and acclimatisation in the villages of Güicán or El Cocuy beforehand is important. Park entry requires a guide for the higher routes, an early start, and adherence to strict rules that keep walkers off the glaciers to protect the ice. Access can close at short notice.

The dry season, from December to February and again around July and August, offers the clearest skies and safest footing; the wetter months bring cloud, ice and closures. Warm layers and sun protection are essential at altitude. With its frailejones, glacial lakes and shining peaks, the Cocuy offers some of the most rewarding high-altitude day walking in Colombia.
