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 Valley of the Rocks is one of Exmoor's most famous and striking geological features. This very popular 3.8-mile (6km) circular walk starts in the picturesque Victorian cliff-top town of Lynton. The outward leg follows a relatively flat, fully paved section of the South West Coast Path, carved directly into the sheer cliff face high above the Bristol Channel. Upon reaching the Valley—a surreal, dry U-shaped valley littered with massive, jagged gritstone rock formations (tors) and a resident herd of feral goats—the route loops back inland via the higher ground of Hollerday Hill. It is a walk of immense, dramatic coastal views requiring very little sustained climbing.
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.
