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.
A journey through fire and forest. The Puyehue Traverse is a stunning multi-day route in Puyehue National Park, part of the Northern Patagonian Andes. The trek typically focuses on the ascent of the 2,240m Volcán Puyehue, transitioning from the Valdivian temperate rainforest—rich in ancient coihue trees and wildlife—to the stark, surreal scoria fields of the volcano's upper slopes. The highlight is reaching the massive, 2.5km-wide crater, which offers views over the Cordón Caulle fissure (site of a major 2011 eruption). The trek is unique for its geothermal activity, with natural hot springs (termas) providing a perfect post-climb recovery in the wild.
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.
