Cordillera Blanca Traverse (CBT)
The significant Andean high-route. The Cordillera Blanca Traverse (CBT) is a 400km long-distance epic that navigates the sheer walls and glacial valleys of the world's highest tropical mountain range. Conceceived as a continuous high-route, it crosses over 20 passes above 4,400m, reaching a maximum altitude of 5,200m. This is not just a hike; it is a high-altitude odyssey that links famous sectors like Santa Cruz and Alpamayo with completely unknown, pristine glacial valleys. Trekkers move through a landscape of more than 700 glaciers and 300 emerald lakes, constantly shadowed by 6,000m giants like Huascarán and Artesonraju (the 'Paramount Pictures' mountain).
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.
Head-to-Head Metric Analysis
HikeMetrics Hazard Scale — Explanation
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.
