Three Passes Trek

EXTREME // LETHAL
Full Route Report

The significant high-altitude loop. The Three Passes Trek is the most ambitious and physically demanding route in the Everest region. It connects the four main valleys of the Khumbu by crossing three formidable high passes: Kongma La (5,535m), Cho La (5,420m), and Renjo La (5,360m). Unlike the linear EBC trek, this giant loop provides a comprehensive view of the entire Everest massif, taking you away from the main crowds into the rugged, high-altitude wilderness where few others venture. Each pass offers a unique perspective of the 8,000m giants, making it a masterpiece of Himalayan trekking.

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.

EXTREME // LETHAL

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
Three Passes Trek
EXTREME // LETHAL
extreme altitude fatigue: Spending almost 10 days consistently above 4,800m is taxingly strenuous on even the fittest hikers.
technical pass navigation: Passes like Kongma La and Cho La can be incredibly tricky to navigate if clouds come in or if there is fresh snow over the boulders/glaciers.
Route B // 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.
