Arctic Circle Trail (ACT)

EXPERT // HAZARD
Full Route Report

The Arctic Circle Trail (ACT) is a legendary 165km wilderness trek that carves through the heart of West Greenland. Connecting the inland hub of Kangerlussuaq with the coastal bustle of Sisimiut, the trail traverses the Aasivissuit–Nipisat UNESCO World Heritage site—a cultural hunting landscape that has sustained Inuit cultures for over 4,000 years. The journey takes you through a vast, treeless tundra where the only company you'll have are the occasional muskox or reindeer. It's a land of rolling hills, sapphire-blue lake systems, and profound silence, offering one of the most immersive long-distance wilderness experiences in the Arctic.

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.

EXTREME // LETHAL

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.

Full Scale Documentation
Route A // Hazard Verdict
Arctic Circle Trail (ACT)
EXPERT // HAZARD
extreme isolation: Rescue operations are helicopter-based and can be logistically complex and costly. A satellite device is strongly recommended.
river crossings and bogs: Early season melt can make stream crossings dangerous, and bogs can be waist-deep.
Route B // Hazard Verdict
Liechtensteinklamm — The Helix Chasm
LOW // ACCESS
steep stair climb: The main physical demand is the 440-step staircase section.
