Model-based (not a field report) · Evaluates overall route demand, not danger.
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.
Travessia Petrópolis-Teresópolis (Serra dos Órgãos NP)
The Travessia Petrópolis-Teresópolis is a premier multi-day traverse within the Serra dos Órgãos National Park (PARNASO). Spanning approximately 30km, the route reaches its peak at Pedra do Sino (2,263m). The trek transitions from dense Atlantic Rainforest to exposed granite plateaus. Route basics: 1. Officially known as Travessia Petrópolis-Teresópolis. 2. Located within PARNASO. 3. Requires advanced booking for 'Abrigo' shelters. 4. Iconic 'Cavalinho' scramble is the technical crux. 5. High risk of white-out fog (nevoeiro) on the ridge. 6. Best hiked between May and September.
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.
