Kaisertal — The Stairway to Heaven

MODERATE // CHLG
Full Route Report

Voted Austria’s most beautiful place in a national poll in 2016, the Kaisertal is a legendary valley nestled between the Zahmer Kaiser and Wilder Kaiser massifs. For decades, it was the only inhabited valley in Austria with no road access. Even today, only residents are allowed to drive, making it a hiker's paradise. The journey begins with the 'Kaiseraufstieg'—a relentless series of nearly 300 vertical steps that lead over the Sparchner Gorge. Once past the stairs, the valley opens into a pastoral world of historic mountain inns, chapels, and soaring vertical limestone walls.

Full Route Report

Technically Stage 8 of the Swiss Via Alpina, this traverse crosses the border between the Cantons of Glarus and Uri. Starting at Urnerboden—Switzerland's largest alpine pasture—the trail climbs toward the Klausenpass before a massive, spectacular descent into the Schächental valley. The path stays high on the sunny northern slope (the 'Schächentaler Höhenweg'), offering constant views of the jagged Glarus Alps and the limestone spires of the Schärhorn. It is a hike of immense scale and pastoral charm, passing through active cheese-making settlements.

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.
