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 Sörmlandsleden is a sprawling 1,000km trail network threading through the Södermanland province south of Stockholm. Segment 1 (Etapp 1) is its grand entrance. Dropping you right into the Nacka Nature Reserve from the edge of the city, this5km (5.2-mile) hike is legendary for its accessibility. Starting quite literally at a Stockholm subway station (Björkhagen), hikers are instantly swallowed by deep forests and granite outcrops. The exceptionally well-marked trail winds past four major lakes (including Söderbysjön and Sandasjön), offering numerous swimming spots, pristine natural springs, and designated barbecue areas before finishing at Skogshyddan.
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.
