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.

Slim’s River West Trail (Ä’äy Chù West)

EXPERT // HAZARD
Full Route Report

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.

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.
