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.

Nakasendo Trail (中山道)

STANDARD // RT
Full Route Report

A walk through the Edo period. The Nakasendo (中山道) was one of the 'Gokaido' (Five Routes) of the Edo period (1603-1868), connecting Kyoto and Edo (Tokyo). While much of the route has been modernised, the 'Kiso-ji' section in the deep Kiso Valley remains beautifully preserved. Hiking between the post-towns of Magome and Tsumago follows the original stone-paved path (ishidatami) through cedar forests and over historical passes. With their dark wooden buildings and absence of cars, these towns represent a significant cultural legacy of Japan's inland history.

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.
