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.
Zhangjiajie National Forest Park is a surreal landscape widely associated with and often cited as the inspiration for the floating 'Hallelujah Mountains' in the movie Avatar. The park is defined by over 3,000 towering, incredibly narrow quartz-sandstone pillars, many rising over 200 meters, cloaked in dense, sub-tropical jungle and frequently shrouded in mist. Hiking here involves navigating a massive, highly developed geological park. The hiking paths are heavily engineered—consisting of thousands of paved stone stairs, cliff-side walkways (including glass skywalks on Tianmen Mountain nearby), and massive outdoor elevators (like the 326m-tall Bailong Elevator).
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.
