Illampu Circuit vs Salkantay Trek: Intensity Score Comparison
Both routes share a similar overall intensity (84 vs 89). Depending on personal strengths, the challenge relies more on Salkantay Trek's technicality versus the physical output of the other.

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.
The wild road to Machu Picchu. Voted one of the top 25 treks in the world by National Geographic, the Salkantay Trek (approx. 74km / 46 miles) is the premier alternative to the classic Inca Trail. It is a physically more demanding route that avoids the stone steps and restricted permits of the Inca Trail, instead focusing on high-altitude glacial landscapes and diverse ecological zones. You traverse the high Salkantay Pass (4,630m) under the shadow of the massive 'Apu' Salkantay glacier before descending into tropical cloud forests and coffee plantations.
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.
