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 Wilderness Coast Walk is a remote, point-to-point coastal trek of roughly 100 km, linking the Merrica River trailhead in South East NSW (Nadgee Nature Reserve) to Mallacoota Inlet in Gippsland, Victoria (Croajingolong National Park). The route traverses expansive sand dunes, sandstone headlands, and coastal heathlands along the Tasman Sea, with optional extensions to Green Cape. Navigation relies on tidal windows and topographic cues, as much of the track is unmarked. The walk passes through critical habitats for species such as the White-bellied Sea Eagle. Permits are required from NSW National Parks & Wildlife Service and Parks Victoria.
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.
