The John Muir Trail (JMT)

EXTREME // LETHAL
Full Route Report

The finest mountain trek in America. The John Muir Trail (JMT) passes through what Muir called the 'Range of Light'—the High Sierra of California. Over 340km, the trail traverses Yosemite, Ansel Adams Wilderness, Devils Postpile, and Kings Canyon, ending at the summit of Mount Whitney (4421m). It is a world of granite cathedrals, thousands of alpine lakes, and high mountain passes that stay snow-capped well into summer. This is pure, high-altitude wilderness at its most spectacular.

Perito Moreno Glacier Trail

EXPERT // HAZARD
Full Route Report

Guided glacier trekking on the Perito Moreno Glacier is a specialized activity within Los Glaciares National Park. The glacier, covering approximately 250 square kilometers, is one of the few advancing ice masses in the Patagonian Andes. Access to the ice surface is strictly regulated and conducted via two primary excursion formats: the 'Minitrekking' (introductory) and the 'Big Ice' (extended exploration). Participants navigate a dynamic landscape of crevasses, moulins, and ice ridges using technical equipment under professional supervision. The experience provides a direct perspective on glacial movement and the hydrological processes of the Southern Patagonian Ice Field.

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
The John Muir Trail (JMT)
EXTREME // LETHAL
altitude sickness: Much of the trail stays above 3,000 meters. Altitude sickness (AMS) is a real risk.
bear encounters: The Sierra is home to persistent and intelligent Black Bears.
Route B // Hazard Verdict
Perito Moreno Glacier Trail
EXPERT // HAZARD
dynamic glacier surface: The glacier is in a state of constant motion, resulting in the shifting of ice formations, crevasses, and drainage channels.
high reflective glare: The albedo of the glacier surface results in high UV reflection, which can lead to rapid eye strain or solar retinopathy (snow blindness) without protection.
