The odyssey of diversity. The Heaphy Track is the longest of New Zealand's Great Walks, stretching 78.4km from the Aorere Valley in Golden Bay to Kohaihai on the West Coast. It is a journey of extreme contrast: starting in ancient beech forests, ascending to the Sub-alpine tussock downs of Gouland Downs (home to the Great Spotted Kiwi), and descending through lush podocarp forest to the coastal palm groves. Unlike the steep verticality of the Milford, the Heaphy is a more gradual, long-distance traverse that allows hikers to experience the full spectrum of New Zealand's wilderness ecosystems in one continuous line.
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.
