Grey Glacier and Lago de Grey

STANDARD // RT
Full Route Report

Located inside Torres del Paine National Park in Chilean Patagonia. Starting with incredible views of Cuernos del Paine and Cerro Paine, the day hike to Grey Glacier and Lago Grey features stunning lake and mountain views throughout most of the trail. The 12 km trek is considered one of the easier hikes of the multi-day Torres del Paine W trek, beginning at Camp Paine Grande. The mostly flat and shaded sections offer captivating scenery culminating in a short rocky climb near the end to witness the massive Grey Glacier calving into the glacial lake.

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
Grey Glacier and Lago de Grey
STANDARD // RT
extreme winds: The wind coming off the Southern Patagonian Ice Field across Lago Grey can be forceful, sometimes blowing hikers off their feet.
cold exposure: Even in mid-summer, the ambient temperature near the glacier drops significantly.
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.
