Cerro Tronador (Refugio Otto Meiling)

MODERATE // CHLG
Full Route Report

This two-day Patagonia hike leads to Refugio Otto Meiling on the slopes of Cerro Tronador, one of the most prominent peaks in the Bariloche region. The route climbs through coihue and lenga forests before emerging onto a high rocky ridge that culminates at the refuge (1,905m). Positioned between the Castaño Overa and Alerce glaciers, the stay offers a unique opportunity to witness active glacial calving. The trail follows a well-defined path of forest floor and alpine rock, with a final sustained push to reach the rocky spine where the hut perches.

Illampu Circuit

EXTREME // LETHAL
Full Route Report

The Illampu Circuit is a demanding 6-to-7-day trek that circumnavigates the northern giants of the Cordillera Real: Illampu (6,368m) and Ancohuma (6,427m). Often described as one of Bolivia's most vertically significant non-technical routes, the loop starts and ends in the sub-tropical town of Sorata (2,700m). Much of the circuit sits above 4,000m once the Sorata valley is left behind, crossing multiple high passes including the Abra de la Calzada (~5,045m). The route crosses high-altitude pampas inhabited by Aymara herders and traverses rugged moraine fields directly beneath active glaciers.

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
Cerro Tronador (Refugio Otto Meiling)
MODERATE // CHLG
crevasses: Venturing onto the glaciers without a guide or technical training is extremely hazardous due to hidden crevasses.
rapid_weather_changes: High alpine exposure means severe storms can blow in quickly from the Pacific, even in summer.
Route B // Hazard Verdict
Illampu Circuit
EXTREME // LETHAL
extreme altitude and vertical gain: The trek involves a 2,000m+ initial climb from Sorata and sustains multiple days above 4,300m, peaking at the 5,045m Calzada Pass.
weather and exposure: Night temperatures can drop to -15°C (5°F), and storms can move in rapidly.
