A journey through fire and forest. The Puyehue Traverse is a stunning multi-day route in Puyehue National Park, part of the Northern Patagonian Andes. The trek typically focuses on the ascent of the 2,240m Volcán Puyehue, transitioning from the Valdivian temperate rainforest—rich in ancient coihue trees and wildlife—to the stark, surreal scoria fields of the volcano's upper slopes. The highlight is reaching the massive, 2.5km-wide crater, which offers views over the Cordón Caulle fissure (site of a major 2011 eruption). The trek is unique for its geothermal activity, with natural hot springs (termas) providing a perfect post-climb recovery in the wild.
Urnerboden to Altdorf (Klausenpass Route)
Technically Stage 8 of the Swiss Via Alpina, this traverse crosses the border between the Cantons of Glarus and Uri. Starting at Urnerboden—Switzerland's largest alpine pasture—the trail climbs toward the Klausenpass before a massive, spectacular descent into the Schächental valley. The path stays high on the sunny northern slope (the 'Schächentaler Höhenweg'), offering constant views of the jagged Glarus Alps and the limestone spires of the Schärhorn. It is a hike of immense scale and pastoral charm, passing through active cheese-making settlements.
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.
