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.
Moro Rock is a giant granite dome located in the heart of Sequoia National Park. While arguably more of a monumental staircase than a traditional hike, ascending Moro Rock provides one of the easiest, most accessible, and most dramatic panoramic viewpoints in the entire Sierra Nevada mountain range. A marvel of 1930s Civilian Conservation Corps (CCC) engineering, a concrete and stone stairway consisting of roughly 350 steep steps is bolted directly and seamlessly into the sheer granite face. Hikers climb this narrow spine, with thrilling drop-offs guarded by iron handrails, to reach a flat summit at 6,725 ft (2,050m) that offers uninterrupted, sweeping views of the craggy Great Western Divide.
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.
