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.
The Larapinta Trail is a 223km point-to-point long-distance track in the Northern Territory, Australia. Spanning from the Alice Springs Telegraph Station to the summit of Mount Sonder, the route traverses the spine of the West MacDonnell Ranges (Tjoritja). The landscape is defined by Proterozoic-era quartzite ridges, narrow gorge systems, and ephemeral river beds. The trail possesses deep cultural significance to the Arrernte people and offers exposure to one of the world's oldest geological landscapes.
Head-to-Head Metric Analysis
HikeMetrics Hazard Scale — Explanation
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.
