GR R2 — La Grande Traversée

EXTREME // LETHAL
Full Route Report

The GR R2 is a legendary long-distance trail that traverses the French island of Réunion in the Indian Ocean from north to south. It is widely considered one of the most physically demanding GR trails in the French network due to its extreme verticality and tropical environment. The route crosses the three massive 'Cirques' (natural amphitheaters), climbs the highest peak in the Indian Ocean (Piton des Neiges, 3070m), and borders the active volcanic zone of Piton de la Fournaise.

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.

Route A // Hazard Verdict
GR R2 — La Grande Traversée
EXTREME // LETHAL
verticality: The trail features relentless, steep climbs and descents on slippery volcanic rock.
cyclones: During the wet season (Jan-March), the island is prone to tropical cyclones and landslides.
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.
