Terskey Alatau & Ala-Köl Lake

EXPERT // HAZARD
Full Route Report

Ala-Köl is a world-renowned glacial lake set within the Terskey Alatau range of the Tien Shan, near Karakol. This 3-4 day traverse through the Karakol Valley is widely considered the quintessential Kyrgyzstan trekking experience. The route typically involves ascending the steep 3,860m Ala-Köl Pass, where hikers are met with some of the most dramatic high-alpine vistas in Central Asia. The lake's depth and mineral content produce an ever-shifting spectrum of opaque turquoise and deep blues. The trek concludes in the Altyn-Arashan valley, a lush high-altitude pasture famous for its natural geothermal hot springs set beneath the massive ice-wall of the 5,012m Pik Palatka.

Nahuel Huapi Traverse (4 Refugios)

EXTREME // LETHAL
Full Route Report

The Nahuel Huapi Traverse is a multi-day hut-to-hut route that circumnavigates the mountain ranges adjacent to San Carlos de Bariloche. The trail follows a high-alpine path, connecting four distinct mountain refugios via ridgelines, loose scree slopes, and granite passes. The terrain is characterized by a mix of Andean forest and exposed high-altitude terrain, where route-finding and stability on loose rock are primary requirements. The system of stone huts (refugios) provides a logistical framework for the journey, though hikers must be prepared for sustained physical output in an exposed mountain environment.

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.

Full Scale Documentation
Route A // Hazard Verdict
Terskey Alatau & Ala-Köl Lake
EXPERT // HAZARD
steep loose scree: The descent from the Ala-Kol pass is extremely steep and consists of loose, sliding gravel.
weather instability: Snow, hail, and high-altitude gales can occur even in mid-July.
Route B // Hazard Verdict
Nahuel Huapi Traverse (4 Refugios)
EXTREME // LETHAL
technical scrambling and exposure: Portions of the route, particularly the section between Jakob and Laguna Negra, involve steep terrain with significant fall potential and Class 2-3 scrambling sections on loose rock.
mountain weather variables: The ridgelines are fully exposed to regional weather systems. High winds, temperature drops, and sudden precipitation can occur regardless of the season.
