Liechtensteinklamm — The Helix Chasm
One of the longest, deepest, and most impressive gorges in the Alps. The Liechtensteinklamm is famous for its narrow walls that are so close they almost block out the sky. Following a massive rockfall in 2017, the gorge was upgraded with the 'Helix'—a spectacular spiral staircase made of corten steel that descends 30 meters into the depths of the chasm. The path leads over bridges and through tunnels to a massive 50-meter waterfall at the end of the walkable section.
The Sella-Herbetet Traverse
The Sella-Herbetet Traverse (Traversata Sella–Herbetet) is a primary high-altitude loop within the Parco Nazionale del Gran Paradiso, Aosta Valley. The route connects Rifugio Vittorio Sella (2,584m) with the Casolari dell'Herbetet via a sustained balcony trail. The traverse crosses steep south-facing slopes overlooking the Valnontey valley (Cogne), utilizing narrow paths through rocky karst and scree. Historically a royal hunting preserve, the area supports a high density of Alpine Ibex (Capra ibex), which are frequently observed at elevations above 2,200m. The circuit involves a significant 1,150m vertical gain from the Valnontey valley floor.
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.
