GR5 — Grande Traversée des Alpes
The French section of the renowned GR5 (which technically starts in the Netherlands) serves as the 'Grande Traversée des Alpes' (GTA). This majestic 385-mile (620km) route is Europe’s classic north-to-south Alpine traverse. Starting from the shores of Lake Geneva (Lac Léman) in Thonon-les-Bains, it drives straight south through the heart of the Alps—crossing the Mont Blanc massif, the Vanoise National Park, the Queyras, and the Mercantour National Park—before finally dropping into the Mediterranean Sea at Nice. It takes about 4 weeks to complete, offering a journey from green, pastoral dairy country through high-altitude wilderness, culminating in the lavender-scented maritime Alps.

The Stevenson Trail (GR70)
The GR70, universally known as the Stevenson Trail, traces the historic 1878 journey of Scottish author Robert Louis Stevenson and his donkey, Modestine. This 270km linear hike begins in the volcanic hills of the Haute-Loire, crosses the granite plateau of Mont Lozère, and descends through the forested valleys of the Cévennes National Park to finish in the Gard. It is a premier literary trail passing through ancient chestnut forests and traditional stone villages of the Massif Central. Note: Compiled from public sources — not a field report.
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.
