Annapurna Circuit

EXPERT // HAZARD
Full Route Report

often regarded as one of the most diverse journey. The Annapurna Circuit is a legendary 230km (143 mile) journey that circumvents the massive Annapurna Massif. What makes this trek unique is its incredible ecological diversity—transitioning from lush tropical jungles and terraced rice paddies to pine forests, and finally to the stark, arid, Tibetan-like landscape of the Manang valley. The physical and spiritual climax is the crossing of Thorong La (5,416m), one of the highest trekking passes in the world, before descending into the sacred site of Muktinath.

Chadar Trek (Zanskar River)

EXTREME // LETHAL
Full Route Report

The Chadar Trek is a specialized winter expedition on the frozen Zanskar River in Ladakh. Historically known as the 'Chadar' (blanket of ice), this route served as the primary winter link between the Zanskar Valley and Leh when high mountain passes were impassable due to snow. This trek features non-technical terrain, but an extreme environmental load. The route involves traversing the ice surface within deep limestone canyons. With ambient temperatures frequently dropping below -30°C, the trek requires specialized cold-weather management and an understanding of shifting ice dynamics.

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.

Route A // Hazard Verdict
Annapurna Circuit
EXPERT // HAZARD
acute mountain sickness ams: Thorong La is over 5,400 meters. Many trekkers push too fast from Manang and risk severe AMS on the pass day.
weather on the pass: Blizzards and extreme cold can occur on Thorong La at any time of year, sometimes trapping trekkers.
Route B // Hazard Verdict
Chadar Trek (Zanskar River)
EXTREME // LETHAL
breaking ice and cold shock: The river is hydrologically variable, and ice thickness varies with current speed, creating potential for breakthroughs into the freezing water.
extreme cold: Nighttime temperatures reaching -35°C present a severe risk of hypothermia and frostbite.
