The 'Hardest Section' of the 3,500km Appalachian Trail. The White Mountains of New Hampshire offer a strenuous, beautiful landscape of rugged granite peaks, alpine krummholz (stunted trees), and some of often regarded as one of the most unpredictable weather. This is where the AT leaves the green tunnel and heads above the treeline for extended stretches, crossing the Franconia Ridge and the legendary Presidential Range, including Mount Washington (1917m)—the house of the world's worst weather.
Slim’s River West Trail (Ä’äy Chù West)
A journey to the Ice Age. The Slim’s River West Trail is a rugged 45-60km round-trip trek in the heart of the Yukon’s Kluane National Park. It follows the massive, silt-laden Ä’äy Chù (Slim’s River) valley through vast gravel flats and thickets of willow and dwarf birch. The trail culminates at Canada Creek, but the true objective for most hikers is the grueling 1,200m climb up Observation Mountain. From the summit, you are rewarded with a soul-stirring view of the Kaskawulsh Glacier—a literal ocean of ice that flows from the Saint Elias Mountains, some of the highest peaks in North America. This is raw, unadulterated wilderness where silence is only broken by the wind and the roar of glacial melt.
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.
