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.
Set within Chile's spectacular Vicente Perez Rosales National Park, the Paso Desolación (Desolation Pass) trek showcases the incredible, destructive power of the perfectly-conical Osorno volcano. The classic route runs point-to-point between La Picada and Petrohué; many hikers arrange transport at one end. The day hike traverses barren volcanic ash fields and lava flows, offering a stark contrast to the nearby lush, verdant forests. Along the route, hikers are treated to mesmerizing panoramic views stretching across the emerald-green waters of Lake Todos los Santos and the jagged peaks of Mount Tronador in the distance.
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.
