Mount Fitz Roy (Cerro Fitz Roy)

EXPERT // HAZARD
Full Route Report

The trek to Laguna de los Tres is one of the primary day activities in Los Glaciares National Park, providing a close-perspective view of the granite massif of Mount Fitz Roy (3,405m). The route follows an out-and-back trail through mixed forest and glaciated valleys, passing the Piedras Blancas viewpoint before the final ascent. The journey is defined by a significant transition from the low-lying valley floor to the high-alpine environment of the lagoon, which sits directly below the main peaks.

Rainbow Mountain (Vinicunca)

MODERATE // CHLG
Full Route Report

A visually staggering, high-altitude approach to Vinicunca. Only discovered by mass tourism a decade ago when the snow melted, the 'Rainbow Mountain' gets its surreal, striped appearance from layers of sediment—goethite, oxidized limonite, chlorite, and more. While the hike itself is relatively short and visually astonishing with llamas grazing against a backdrop of the Ausangate glacier, the overwhelming altitude makes this heavily trafficked trail a serious physical undertaking.

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
Mount Fitz Roy (Cerro Fitz Roy)
EXPERT // HAZARD
high wind exposure: Strong winds are common in the Fitz Roy massif, particularly in the afternoon. Gusts can make the final ascent unstable in exposed conditions.
lower limb strain: The final descent is steep and rocky, which can strain knees and ankles on the return journey.
Route B // Hazard Verdict
Rainbow Mountain (Vinicunca)
MODERATE // CHLG
acute mountain sickness: Altitude sickness (Soroche) hits fast here. The 5,200m peak is higher than Mont Blanc or Mount Whitney.
weather exposure: Sudden blizzards and extreme cold are common, turning the 'Rainbow' into a complete white-out.
