Liechtensteinklamm — The Helix Chasm

LOW // ACCESS
Full Route Report

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 Otter Trail

EXPERT // HAZARD
Full Route Report

South Africa's highly recognizable and exclusive multi-day hike. The Otter Trail follows the rugged, pristine coastline of the Tsitsikamma National Park. Over 5 days, you'll cross steep coastal plateaus, navigate through dense indigenous forests, and time your river crossings with the tides. With limited permits and incredible marine life sightings (dolphins and whales), it is the significant rite of passage for South African hikers.

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.
