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.
Sarek National Park is considered Europe's last true wilderness: no marked trails, no cabins, no bridges over raging glacial rivers, and no cell service. However, on the very eastern edge of Sarek lies Mt. Skierfe (1,179m), boasting a sheer 700-meter vertical drop overlooking the braided, turquoise waters of the Rapadalen delta. The view from the top is universally acclaimed as the most beautiful in all of Sweden. To reach it without undertaking a strenuous 10-day survival expedition deep into Sarek, hikers take a multi-day detour off the Kungsleden trail to the STF Aktse hut. From Aktse, Skierfe is climbed as a demanding 10-mile (16km) round-trip day hike through dense birch forests and steep alpine tundra, terminating at the demanding, unprotected cliff edge.
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.
