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.

Prossautal — A Glacial Box Valley in Hohe Tauern
Deep within the Hohe Tauern National Park, the Prossautal is a valley that branches off the Kötschachtal near Bad Gastein. This long but mostly flat trail follows the Kötschach Ache river into a classic glacial box valley. The rock walls on either side rise significantly, with multiple thin waterfalls cascading down the granite faces. The trail ends at the Alpengasthof Prossau, a traditional alpine inn positioned near the base of the Tischler glacier.
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.
