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.
The wild heart of the Rockies. Stretching over 1,100km from Waterton Lakes National Park to Kakwa Provincial Park, the Great Divide Trail (GDT) is a loosely connected series of trails, old forestry roads, and off-trail cross-country segments. It follows the Continental Divide, crossing between Alberta and British Columbia dozens of times. Unlike the well-manicured PCT or AT, the GDT is famous for its 'trail-less' sections where hikers must navigate by line-of-sight and topographical markers. It traverses some of the most spectacular and remote regions in the Canadian Rockies, through territory where bears and wolves are far more common than humans.
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.
