Illampu Circuit

EXTREME // LETHAL
Full Route Report

The Illampu Circuit is a demanding 6-to-7-day trek that circumnavigates the northern giants of the Cordillera Real: Illampu (6,368m) and Ancohuma (6,427m). Often described as one of Bolivia's most vertically significant non-technical routes, the loop starts and ends in the sub-tropical town of Sorata (2,700m). Much of the circuit sits above 4,000m once the Sorata valley is left behind, crossing multiple high passes including the Abra de la Calzada (~5,045m). The route crosses high-altitude pampas inhabited by Aymara herders and traverses rugged moraine fields directly beneath active glaciers.

Full Route Report

The Snowman Trek is a high-altitude longitudinal traverse of the Bhutanese Himalayas, transiting through the remote Lunana District (Snowman Trek) District (Snowman Trek) District (Snowman Trek) District (Snowman Trek) District (Snowman Trek) District (Snowman Trek) District (Snowman Trek) District (Snowman Trek) District (Snowman Trek) District (Snowman Trek) district. Spanning approximately 330 kilometers, the route crosses 11 mountain passes, with several exceeding 5,000 meters. The traverse is categorized as one of the most demanding multi-day routes globally due to its 25-30 day duration and sustained exposure to altitudes above 4,000 meters. The trail provides a cross-section of the Eastern Himalayan glacial systems and the cultural landscapes of isolated herding communities in the northern frontier. Access is managed by the Bhutanese Department of Tourism and requires specialized logistical support including horse-supported supply chains.

The HikeMetrics Hazard Scale is a proprietary 5-point classification system that evaluates hiking routes across five dimensions: physical demand, technical complexity, altitude exposure, weather risk, and rescue accessibility.

Unlike generic star ratings, the Hazard Scale is calibrated against altitude profiles, elevation gain per day, and logistical isolation factors — making it the most precise route classification system available.

Full Scale Documentation
Route A // Hazard Verdict
Illampu Circuit
EXTREME // LETHAL
extreme altitude and vertical gain: The trek involves a 2,000m+ initial climb from Sorata and sustains multiple days above 4,300m, peaking at the 5,045m Calzada Pass.
weather and exposure: Night temperatures can drop to -15°C (5°F), and storms can move in rapidly.

EXTREME // LETHAL
Sustained Elevation Stress: Prolonged exposure to reduced oxygen levels. Unlike shorter treks, the risk here is the cumulative impact of 20+ days above 4,000m.
Logistical Chain Severance: Pass closures due to snow can isolate groups. The route relies on horse-borne logistics for food and fuel.
