Prossautal — A Glacial Box Valley in Hohe Tauern

LOW // ACCESS
Full Route Report

Deep within the Hohe Tauern National Park, the Prossautal is a valley that branches off the Kötschachtal near Bad Gastein. This long but mostly flat trail follows the Kötschach Ache river into a classic glacial box valley. The rock walls on either side rise significantly, with multiple thin waterfalls cascading down the granite faces. The trail ends at the Alpengasthof Prossau, a traditional alpine inn positioned near the base of the Tischler glacier.

Sulphur Skyline

MODERATE // CHLG
Full Route Report

A summit hike with a hot spring finish. Sulphur Skyline is one of Jasper National Park's most popular short summit hikes. It offers a sustained, steep climb through lodgepole pine forest that eventually breaks out onto a rocky alpine ridge with 360-degree views of the Canadian Rockies. The highlight is the finish: the trailhead is located directly at the Miette Hot Springs, allowing you to soak in the hottest natural springs in the Rockies immediately after descending.

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.
