Alta Via 1 is a primary long-distance mountain trail in the Italian Dolomites, extending from Lago di Braies in the north to Belluno in the south. The trek traverses significant limestone massifs including the Fanes-Sennes-Prags Nature Park, the Tofane, Pelmo, and Civetta. Far from the more technical via ferrata-heavy routes in the range, the standard Alta Via 1 (High Route 1) is an established high-altitude hiking path accessible to fit hikers without technical climbing equipment. The route stays predominantly on high-alpine balconies and plateaus, offering a comprehensive transect of the Central Dolomites.
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.

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.
