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.

Graukogel — Pine Forests & strenuous Ridges

EXPERT // HAZARD
Full Route Report

Standing sentinel over the Belle Époque spa town of Bad Gastein, the Graukogel is a mountain of contrasts. It is famous for its ancient 'Zirbenwald' (stone pine forest), with trees over 300 years old. While the 'Zirbenweg' near the cable car station is a gentle sensory walk, the true Graukogel experience involves the strenuous, steep ascent to the summit (2,492m) and the traverse to the Palfnersee lake. The terrain transitions from scented forest to unforgiving granite ridges and scree, offering unparalleled views of the High Tauern's 'main chain' and the Ankogel massif.

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.

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
Graukogel — Pine Forests & strenuous Ridges
EXPERT // HAZARD
sustained and demanding ascent: The ascent from the middle station to the summit is very steep and continuous.
steep rocky ridge sections: The ridge path toward the Palfnersee involves navigating large granite blocks requiring careful foot placement; they can be slippery when wet.
