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 finest walk in the world. The Milford Track (53.5km / 33 miles) is New Zealand's most famous trekking route, limited to just 40 independent walkers per day. Starting with a boat journey across Lake Te Anau, the trail traces the Clinton and Arthur Valleys, crossing the legendary Mackinnon Pass (1,154m). The track is characterized by massive U-shaped glacial valleys, vertical granite walls, and hundreds of waterfalls—including Sutherland Falls, the tallest in New Zealand. It ends at Sandfly Point, where a final boat takes you to the iconic Milford Sound.
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.
